TOWER GROUNDING PART 1: GENERAL 1.1 SUMMARY

A. This specification covers general requirements for grounding and bonding towers. B. An external grounding electrode system for a communications tower is required to disperse

lightning energy to earth before it is able to enter the associated communications structure (or enclosure). Although it is impossible to prevent all lightning energy from entering the communications structure, the majority of the lightning energy can be controlled and diverted to earth. Antenna masts and metal support structures shall be grounded.

C. For towers installed at high lightning prone geographical areas or sites normally occupied (such as 911 dispatch centers), radial grounding conductors should be employed to improve equalization of the grounding electrode system. This is recommended even if the grounding electrode system resistance requirement is met without the use of radial grounding conductors.

D. Some antenna structures, such as water storage tanks, may require special grounding and bonding techniques due to the possibility of corrosion and should be designed by a licensed engineer.

END OF SECTION 33 79 83.13

GROUND PLATE INSTALLATION


SECTION 33 79 83.20 SUPPLEMENTAL GROUNDING ELECTRODES


A. At sites where poor soil conductivity, limited space, or adverse terrain exists, an acceptable grounding-electrode-system resistance cannot be achieved using standard ground rods. Commercially available alternative grounding methods should be considered. There are several alternative grounding products available, and these can be used in conjunction with or as an alternative to standard ground rods. 1. Electrolytic ground rods should be considered for use in grounding electrode systems covered

by concrete or pavement, such as parking lots. By allowing moisture to enter, the design of the electrolytic ground rod improves the resistance of the grounding electrode system. (See also Section 33 79 83.20a – Electrolytic Ground Rods)

2. Grounding Plate Electrodes should only be used if soil conditions prohibit the use of standard ground rods, or if specifically engineered into the grounding electrode system.

3. Concrete-Encased Electrodes (also known as Ufer electrodes, named after Herbert G. Ufer, or foundation earth electrodes) are not required, they should be used in new construction as a method of supplementing the grounding (earthing) electrode system. Concrete-encased electrodes enhance the effectiveness of the grounding electrode system in two ways: the concrete absorbs and retains moisture from the surrounding soil, and the concrete provides a much larger surface area in direct contact with the surrounding soil.

4. Radial Grounding Conductors should be employed to improve equalization of the grounding electrode prone geographical areas, sites normally occupied (such as 911 dispatch centers), sites with high soil resistivity, or when bedrock prohibits the driving of ground rods. Radial grounding conductors are conductors installed horizontally in the ground and radiating away from the tower and building.

A. Electrolytic rods are covered in more detail in Section 33 79 83.33 and NFPA 70-2014, Article 250.52 (A) (5) Rod and Pipe Electrodes.

2.3 GROUND PLATE ELECTRODES

A. Ground plate electrodes shall be as follows: 1. Ground plates must be listed (UL 467 or equivalent). 2. Ground plates shall be constructed of copper or copper-clad steel. 3. Ground plates shall expose not less than two square feet of surface to exterior soil. 4. Ground plates of copper or copper-clad steel shall have a minimum thickness of 0.06 inches. 5. Ground plates of bare or conductively coated iron or steel plates shall be at least 0.25 inches in

thickness. 6. Ground plates shall be free of paint or other nonconductive coatings.

2.4 CONCRETE ENCASED ELECTRODES

A. An electrode encased by at least 2 inches of concrete, located horizontally near the bottom or vertically, and within that portion of a concrete foundation or footing that is in direct contact with the earth.

B. Concrete-encased electrodes shall be at least 20 feet of one or more bare or zinc galvanized or other electrically conductive coated steel reinforcing bars or rods of not less than 0.5 inches in diameter, or consisting of at least 20 feet of bare copper conductor not smaller than 4 AWG.

C. Reinforcing bars shall be permitted to be bonded together by the usual steel tie wires or other effective means. Where multiple concrete-encased electrodes are present at a building or structure, it shall be permissible to bond only one into the grounding electrode system.

2.5 RADIAL GROUNDING CONDUCTORS

A. For high lightning prone geographical areas, sites normally occupied (such as 911 dispatch centers), sites with high soil resistivity, or when bedrock prohibits the driving of ground rods, radial (counterpoise) grounding conductors should be employed to improve equalization of the grounding electrode system, and to help meet the site's grounding electrode system resistance requirements. Radial grounding conductors are conductors installed horizontally in the ground and radiating away from the tower and building.

B. In typical soil resistivity conditions of 10,000 ohm-cm, the addition of five radial conductors 25 feet in length may reduce the tower grounding electrode system resistance by a factor of two or three. More importantly, adding radial conductors divides lightning strike current into segments that allow for more effective dissipation of energy into the earth, and away from the equipment building.

C. Low resistance in radial (counterpoise) grounding configurations is desirable, but not critical. Low resistance in the dissipating path of strike currents into the earth is of secondary importance when compared to the primary objective of controlling voltage gradients and voltage differences between structures and equipment close to the tower. 1. The conductors shall be constructed of #2 AWG or coarser, bare, solid, tinned or un-tinned,

copper. 2. When soil conditions allow, the effectiveness of the radial grounding conductor may be

increased by including a ground rod every 16 ft., or twice the length of the ground rods installed.

2.6 GROUNDING ELECTRODE ENCASEMENT MATERIALS

A. Grounding electrode encasement material may be used as needed to improve the grounding electrode system resistance and/or to protect the grounding electrode system components from corrosive soil. Grounding electrode encasement material is generally used with electrolytic ground rods, but may also be used on grounding conductors, standard ground rods, and ground plates as a way to improve the resistance to earth of a grounding electrode system.


1. Per MIL-HDBK-419A, the suggested grounding electrode encasement (backfill) material is a mixture of 75 percent gypsum, 20 percent bentonite clay, and 5 percent sodium sulfate. The gypsum, which is calcium sulfate, absorbs and retains moisture and adds reactivity and conductivity to the mixture. Since it contracts very little when moisture is lost, it will not pull away from the ground rod or surrounding earth. The bentonite ensures good contact between the ground rod and earth by its expansion, while the sodium sulfate prevents polarization of the ground rod by removing the gases formed by current entering the earth through the ground rod. This mixture is readily available from cathodic protection distributors as standard galvanic anode backfill. The backfill mixture should be covered with 305 mm (12 in.) of excavated soil.

2. Grounding electrode encasement material shall be packaged for the purpose of grounding electrode encasement.

3. Grounding electrode encasement material shall be environmentally safe and approved by the environmental authority having jurisdiction.

4. Grounding electrode encasement material shall not have a corrosive effect on the grounding electrode system components.

5. The use of charcoal or petroleum based coke breeze is not recommended as it may result in rapid corrosion of copper electrodes and copper conductors. Charcoal and petroleum based coke typically contains high levels of sulfur, which in the presence of moisture will accelerate corrosion. Coke breeze derived from coal in coke ovens is generally considered acceptable; all the corrosives and volatiles have been cooked off at extremely high temperatures.

PART 3: EXECUTION 3.1 INSTALLATION

A. ELECTROLYTIC GROUND ROD INSTALLATION (See Section 33 79 83.33 – Electrolytic Ground Rods)

B. GROUND PLATE ELECTRODE INSTALLATION 1. Ground plates should only be used if soil conditions prohibit the use of standard ground rods, or

if specifically engineered into the grounding electrode system. 2. Ground plates shall be buried not less than 30 inches below the surface of the earth. If soil

conditions do not allow the ground plate to be buried at this depth, follow the instructions for Shallow Topsoil Environments, Section 4.11.6 of Motorola R56.

3. Where practical, a ground plate shall be embedded below permanent moisture level. 4. Ground plates should be installed vertically to allow for minimum excavation and better contact

with the soil when backfilling. 5. A “grounding electrode encasement material” should be used to backfill around the ground plate

to help assure effective contact with the earth. C. CONCRETE ENCASED ELECTRODE INSTALLATION

1. Concrete-encased electrodes shall be encased by at least two (2) inches of concrete, located within and near the bottom of a concrete foundation or footing that is in direct contact with the earth.

2. Concrete-encased electrodes shall be bonded to any other grounding electrode system at the site.

D. RADIAL GROUNDING CONDUCTOR INSTALLATION 1. The conductors shall radiate away from the building and tower. 2. The conductors shall be installed at the tower or tower ground ring whenever possible. If the

conductors cannot be installed at the tower, installation at the building is acceptable, but should be installed near the RF transmission line entry point.

3. When radial conductors are used, a minimum of three to five conductors should be used. 4. The conductors shall be installed equally spaced from one another, as much as practical. 5. The conductors shall be bonded directly to the tower and tower ground ring. If it is not practical

to bond all conductors to the tower, the tower shall have additional grounding conductors bonding it to the tower ground ring; #2/0 AWG or coarser conductor is recommended in this case.

6. The conductors shall be buried at least 18 inches below ground. When topsoil conditions allow, it is recommended to bury the conductors to a depth of at least 30 inches which is especially important in areas where the frost line may reach 18 inches.


7. The minimum length of each conductor shall be 25 feet. If the desired resistance to earth is not achieved at 25 feet, the radial conductor may be extended to help obtain the desired resistance. The maximum effective length for a single radial conductor is generally considered to be approximately 80 feet. Adding additional conductors is generally more effective than extending the length of a single conductor.

8. When multiple radial conductors are used, the conductors should be of different lengths to help prevent resonant “ringing” of the tower from a lightning strike.

E. GROUNDING ELECTRODE ENCASEMENT INSTALLATION 1. Grounding electrode encasement material shall be used in accordance with the manufacturers'

instructions. 2. Concrete-encased electrodes shall be encased by at least 2 inches of concrete, located within

and near the bottom of a concrete foundation or footing that is in direct contact with the earth. 3. Concrete-encased electrodes shall be at least 20 feet of bare copper conductor not smaller

than #4 AWG or at least 20 feet of one or more bare or zinc galvanized or other conductive coated steel reinforcing bars or rods at least 0.5 inches in diameter.

4. Concrete-encased electrodes shall be bonded to any other grounding electrode system at the site.



SECTION 33 79 83.33 ELECTROLYTIC GROUND RODS


A. Electrolytic ground rods are generally constructed of 2.125-inch diameter hollow copper pipe. This copper pipe is filled with a mixture of non-hazardous natural earth salts. Holes at various locations on the pipe allow moisture to be hygroscopically extracted from the air into the salt within the pipe, therefore forming conductive electrolytes. These electrolytes then leach out of the pipe into the soil, improving soil conductivity.

B. Electrolytic ground rods should be considered at radio sites where the following conditions exist: 1. Preliminary testing reveals poor soil conductivity (high resistivity). 2. Limited space is available for compliant installation of a shelter or tower ground ring. 3. An acceptable grounding electrode system resistance cannot be achieved using standard

ground rods. 4. Grounding electrode systems are covered by concrete or pavement, such as parking lots.

C. Electrolytic ground rods may provide significant improvement over standard ground rods of the same length and may last several years longer than standard ground rods. The resistance to earth of electrolytic ground rods is generally more stable in environments with variations in temperature and moisture.

2. The chemical charge within the rod electrode shall be a substance that does not cause the electrode to corrode at a faster rate than an electrode constructed of trade size 3/4 rigid ferrous metal conduit.


3. A chemical charge of 60 percent sodium chloride and 40 percent calcium chloride may be used if the total weight of the charge is less than 11 lbs.

2.2 GROUNDING ELECTRODE ENCASEMENT MATERIAL

A. Grounding electrode encasement material may be used as needed to improve the grounding electrode system resistance and/or to protect the grounding electrode system components from corrosive soil. Grounding electrode encasement material is generally used with electrolytic ground rods, but may also be used on grounding conductors, standard ground rods, and ground plates as a way to improve the resistance to earth of a grounding electrode system. 1. Per MIL-HDBK-419A, the suggested grounding electrode encasement (backfill) material is a

mixture of 75 percent gypsum, 20 percent bentonite clay, and 5 percent sodium sulfate. a. The gypsum, which is calcium sulfate, absorbs and retains moisture and adds reactivity

and conductivity to the mixture. Since it contracts very little when moisture is lost, it will not pull away from the ground rod or surrounding earth.

b. The bentonite ensures good contact between the ground rod and earth by its expansion, while the sodium sulfate prevents polarization of the ground rod by removing the gases formed by current entering the earth through the ground rod.

c. This mixture is readily available from cathodic protection distributors as standard galvanic anode backfill.

2. Grounding electrode encasement material shall be packaged for the purpose of grounding electrode encasement.

3. Grounding electrode encasement material shall be environmentally safe and approved by the environmental authority having jurisdiction.

4. Grounding electrode encasement material shall not have a corrosive effect on the grounding electrode system components.

5. The use of charcoal or petroleum based coke breeze is not recommended as it may result in rapid corrosion of copper electrodes and copper conductors. Charcoal and petroleum based coke typically contains high levels of sulfur, which in the presence of moisture will accelerate corrosion. Coke breeze derived from coal in coke ovens is generally considered acceptable; all the corrosives and volatiles have been cooked off at extremely high temperatures.

PART 3: EXECUTION 3.1 ELECTROLYTIC GROUND ROD INSTALLATION

A. Electrolytic rods shall be installed per the specific manufacturers’ recommendations based on the following minimum requirements. 1. Vertical electrolytic ground rods must be inserted into a pre-drilled hole and encased in a

grounding electrode encasement material. 2. L-shaped electrolytic ground rods (horizontal portion) shall be installed in a trench at least 30

inches deep and encased in a grounding electrode encasement material. 3. L-shaped electrolytic ground rods (horizontal portion) shall be installed perpendicular to the

building or shelter. B. If practicable, electrolytic ground rods shall be embedded below permanent moisture level. C. Unless prohibited by local environmental authorities, condensation from the site's HVAC system

may be routed to the electrolytic ground rod area to keep the soil moist, improving conductivity. D. Grounding electrode encasement material shall be installed per manufacturer’s instructions. The

backfill mixture should be covered with 12 inches of excavated soil.


SECTION 33 79 83.53 GROUNDING ELECTRODE SYSTEM RESISTANCE


A. Procedures in this section shall not be performed by untrained or unqualified personnel, nor are any procedures herein intended to replace proper training. It is required that personnel attempting to measure the resistance of a grounding electrode system receive prior formal training on the subject and on its associated safety hazards. All applicable laws, rules and codes regulating the work on electrical systems shall be complied with at all times.

B. This section provides procedures for performing resistance testing of the site grounding electrode system. The resistance of a grounding electrode system shall be measured after its installation and before it is bonded to the power company neutral wire or any other utility, such as the telephone ground or metallic pipes.

C. Although grounding electrode system resistance is important and should be met whenever possible, it alone does not determine the suitability of the grounding electrode system to properly dissipate and control lightning energy. The resistance of the grounding electrode system is only a general measure of merit. Proper design and installation of the grounding electrode system, installation of ground rings, ground rods, radial grounding conductors, and the bonding of systems and equipment, is as important as the resistance to earth.

D. Motorola R56 – Appendix D – Grounding (Earthing) Electrode System Testing/Verification PART 2: PRODUCTS 2.1 TESTING METHODS

A. Testing can be performed using one of the following three methods described in this chapter: 1. Fall-of-Potential Testing

a. This method is the most widely accepted. However, performing the test may require access to areas that may be beyond the site property lines. When testing grounding electrode system consisting of a multi-bonded/multi-grounding electrode system, the distance required for testing is directly related to the effective diagonal distance of the buried grounding electrode system.


2. Clamp-on ohmmeter a. This method should be used when access to necessary space needed for the fall-of-

potential test is not available. However, the clamp-on ohmmeter test can only be performed after the AC utilities have been connected to the site and various feed conductors are accessible.

3. Combined Soil Resistivity Testing with Clamp-on Ohmmeter Testing a. This method should only be used in special cases where fall-of-potential testing or clamp-

on ohmmeter testing cannot directly provide a suitable evaluation. The data obtained from soil resistivity testing and clamp-on ohmmeter testing is then used by an engineering firm specializing in grounding electrode system design to make determinations regarding the grounding electrode system.

2.2 PREREQUISITES FOR TESTING

A. The following conditions must be met in order to perform grounding electrode system testing: 1. Fall-of-Potential testing is possible only if the following conditions can be met:

a. Sufficient land area must be available to perform a fall-of-potential test. The reference probe may likely need to be inserted into soil that is beyond the site fence or property line. Testing using a clamp-on ohmmeter may be an option in these cases.

b. The grounding electrode system must be able to be isolated from the power company grounded conductor (may be a neutral wire) and other utility grounds.

2. Clamp-on ohmmeter testing is possible only if the following conditions can be met: a. The site must be supplied with commercial power. Sites supplied only by a generator or

other non-commercial power may not be suitable for clamp-on ohmmeter testing. b. A neutral wire must be present as part of the power company service. c. A neutral wire must be part of an extensive power company grounding system. In systems

such as 3-phase delta service, the neutral wire may not be part of the extensive power company grounding system.

d. The grounding electrode system must be connected to the power company grounded conductor (may be a neutral wire).

e. For sites using a multi-bonded/multi-grounding electrode system (commonly used at communications sites), a point on the neutral wire before its first bond to the site must be available for using the clamp-on ohmmeter.

f. For a single grounding electrode system, the grounding electrode conductor must be accessible to the clamp-on ohmmeter at a point between the grounding electrode and any other connection (such as the telephone company ground or a metallic pipe).

3. Combined soil resistivity/clamp-on ohmmeter testing is possible only if the following conditions can be met: a. The system must be such that gathering of individual grounding electrode system

component values with a clamp-on-ohmmeter can be available for use by an engineering firm.

b. A soil resistivity profile for the site has been performed and is available for use by an engineering firm.

B. If these conditions cannot be met, an added supplemental grounding electrode system can be installed. This supplemental grounding electrode system can be installed and tested prior to its connection to the existing system. This supplemental system should be installed in such a manner as to allow an easy disconnect point for future testing.

PART 3: EXECUTION 3.1 GROUNDING SYSTEM RESISTANCE TESTING

A. All grounding systems shall be tested using an AEMC or equivalent clamp-on ground resistance tester.

3.2 TYPE-A SITES- LIGHT DUTY Type-A site types typically include Outdoor Cabinets and Fiberglass Shelter with Radom. If the site is considered critical to public safety, Type B Site parameters must be considered. A. Type-A sites typically have the following characteristics:

1. No tower associated with the site. 2. Non-critical installation. 3. Not part of a larger system infrastructure. 4. Single control station. 5. RF alarm/reporting site. 6. Small telemetry cabinet utilizing an existing utility pole to support the antenna. 7. Single voting receiver site. 8. May be located in a commercial office or residence.

B. The minimum grounding system requirement for Type-A Land Mobile Radio sites with an outdoor cabinet or fiberglass shelter with Radom will include a shelter ground ring, external ground bus bar and bonding connections to all external metallic ancillary devices.

C. The grounding system shall achieve a resistance to earth of 25 Ohms or less with a design goal of 10 Ohms. 1. Lessor shall install supplemental grounding as required to achieve the 10-Ohm grounding

resistance goal. D. Lessor shall test the grounding system in the presence of the Design Engineer or Government

approved third party inspector to prove results. E. Lessor shall provide written test results to the Government. F. Lessor shall provide electronic images of the test results to the Government.

3.3 TYPE-“B SITES - STANDARD DUTY

A. Type-B sites shall have a grounding electrode system resistance design goal as low as practical and not over 10 ohms; Motorola recommends a design goal of 5 ohms or less. If the design goal of 10 ohms (or recommended 5 ohms) cannot be achieved with the minimum accepted grounding electrode system, reasonable efforts shall be made to achieve the design goal using supplemental grounding techniques.

B. Type-B sites typically have the following characteristics: 1. A tower is associated with the site. 2. 911 dispatch center. 3. Communications dispatch center. 4. Base station and/or repeater site. 5. Telecommunication repeater equipment is installed, such as cellular, PCS, or wide-area

repeater site. 6. Large installation or multiple systems, such as telephone or electronic switches, LANs/WANs,

D. The grounding system shall achieve a resistance to earth of 10 Ohms or less with a design goal of 5 Ohms. 1. Lessor shall install supplemental grounding as required to achieve the 5-Ohm grounding

resistance goal. E. Lessor shall test the grounding system in the presence of the Design Engineer or Government

approved third party inspector to prove results. F. Lessor shall provide written test results to the Government. G. Lessor shall provide electronic images of the test results to the Government.

C. Motorola R56 – Chapter 4 – External Grounding 1. Section 4.10.5 – Grounding Electrode Systems Covered by Concrete or Asphalt 2. Section 4.11– Special Grounding Situations


A. An effective, low-resistance grounding system for any limited space or high soil resistance communications site can typically be achieved by using products specified in the listed references.

PART 3: EXECUTION 3.1 GENERAL

A. Site conditions such as limited area and high (poor) soil resistivity can sometimes require special consideration for effective grounding. Some methods for achieving an effective grounding electrode system in some common applications are described below in this section. Consultation with an engineering firm may be required in some situations.

3.2 SITES WITH LIMITED SPACE FOR THE GROUNDING ELECTRODE SYSTEM

A. Some sites, such as locations in metropolitan areas or areas close to adjacent buildings or property lines, have very little space available for installing a grounding electrode system. One solution for achieving an acceptable grounding electrode system that meets the resistance requirements defined in the references may be to install a grounding electrode grid system using all available space on the property.

B. A grounding electrode grid system consists of grounding electrodes, typically rods, installed in a grid pattern. The grounding electrodes are all equally spaced and connected together underground with a grounding conductor. Requirements for a grounding electrode grid system are as follows: 1. Whenever possible, the grounding conductors shall be buried at least 30 inches deep or below

the frost line, whichever is deeper.


2. Grounding conductors shall be bonded together wherever they intersect; this is typically completed at a ground rod or other grounding electrode.

3. Bonding of all components shall be made using exothermic welding or listed irreversible high-compression fittings.

C. Burying the grounding conductor in at least six inches of grounding electrode encasement material should also be considered as a method of improving the resistance to ground.

D. In shallow topsoil conditions, the above grounding electrode grid system can utilize ground plates instead of ground rods.

3.3 TOWERS WITH LIMITED SPACE FOR A GROUND RING

A. Towers installed close to a building may not have adequate space for a complete tower ground ring or for ground rods spaced properly to achieve the resistance requirements of the site. Depending on the available space, the tower can be grounded using multiple parallel rods and/or ground radials.

3.4 STONE MOUNTAIN TOPS

A. Some sites are located on mountaintops because of their RF propagation characteristics. In the instances where there is no, or very little, top soil at the site, special designs will be needed. Some options for an effectively grounded site are listed below. Reasonable attempts should be made to use as many options as possible and as needed to meet the ground resistance requirements of the site: 1. Consult with an engineering firm. 2. Installation of concrete-encased electrodes as part of new construction. 3. Installation of radial grounding conductors from the tower and building throughout the property.

Install the radial grounding conductors to a depth allowed by the soil, preferably 18 to 30 inches. Encasing the radial grounding conductors in a grounding electrode encasement material can further increase the effectiveness of the grounding electrode system.

4. Installation of ground rings around the building and tower, with the ground rings buried as deep as the soil will allow. The ground rings should be encased in a grounding electrode encasement material. A conductive concrete may be the best grounding electrode encasement material for use in shallow topsoil environments, since the conductive concrete would not require a covering of topsoil for protection.

5. Installation of horizontal ground rods or horizontal electrolytic ground rods along the length of the ground rings instead of vertical ground rods. The ground rods shall be installed perpendicular to the building and tower. Encasing the ground rings and horizontal ground rods in a grounding electrode encasement material can further increase the effectiveness of the grounding electrode system.

6. Installation of ground plates along the length of the ground rings instead of vertical ground rods. Encasing the ground rings and ground plates in a grounding electrode encasement material can further increase the effectiveness of the grounding electrode system.

7. Installation of down-conductors to a lower area where there is usable soil for the installation of vertical ground rods. The down-conductors would be more effective if buried below ground like a radial grounding conductor, wherever possible. The down-conductors shall be sized according to length. a. Down-conductors alone should not be relied on for an effective grounding electrode

system. Other listed methods and/or options listed in the references should also be used to help achieve an effective grounding electrode system.

b. Installation of copper strap radial grounding conductors on the surface of the rocks in all directions from the tower. The copper straps may be covered with top soil and/or ground enhancing material, such as conductive concrete. Each copper strap radial should be a different length to help prevent ringing of the tower during a lightning strike.

8. At sites, such as stone mountain tops, where it is difficult to achieve an effective grounding electrode system, the need for single-point grounding and transient voltage surge suppression (TVSS) on all input/outputs is of paramount importance.

9. The concept of drilling holes in solid rock to insert a ground rod surrounded by a grounding electrode encasement material is generally considered to be ineffective and should not be used without additional grounding electrode system components. Solid rock is no more


conductive in a hole than on the surface. Radial grounding conductors encased in a grounding electrode encasement material, such as conductive concrete, would be more effective and more economical.

3.5 SAND, CORAL, OR LIMESTONE ENVIRONMENTS

A. Sites with very high soil resistivity, such as sites with sand, coral and limestone, may require special grounding techniques in order to achieve an effectively grounded site. Some options to help achieve an effectively grounded site are as follows: 1. Consult with an engineering firm. 2. Installation of concrete-encased electrodes as part of new construction. 3. In addition to the building and tower ground rings, installation of radial grounding conductors

with vertical ground rods throughout the available property. Encasing all components in a grounding electrode encasement material can further increase the effectiveness of the grounding electrode system.

4. Installation of electrolytic ground rod systems instead of standard ground rods. 5. In addition to the building and tower ground rings, installation of a grounding electrode grid

system throughout the site. 6. Using multiple large copper plates (10 to 20 square feet) buried to an optimal depth of five to

eight feet. The plates are placed vertically on edge and bonded to the grounding electrode system using exothermically welded #2 AWG solid, tinned, copper wire. Placing the plates on vertical edge allows the plates to be buried with a minimum of excavation and may make it possible to obtain more surface area contact with the soil when backfilling. The use of a number of well-placed ground plates in parallel is preferred to placing longer rows of ground plates. Encasing the ground plates in a grounding electrode encasement material can further increase the effectiveness of the grounding electrode system.

3.6 SHALLOW TOPSOIL ENVIRONMENTS

A. Some sites are located in areas where bedrock is near the surface or where the top soil is less than one foot deep. These areas require installation of specialized grounding electrode systems and may require the support of an engineering firm.

B. Requirements and recommendations for grounding electrode systems in areas with shallow topsoil are provided below. Reasonable attempts should be made to use as many options as possible and as needed to meet the ground resistance requirements of the site. 1. Consult with an engineering firm. 2. Installation of concrete-encased electrodes as part of new construction. 3. Installation of ground rings around the building and tower, with the ground rings buried as deep

as the soil will allow. The ground rings should be encased in a grounding electrode encasement material. A conductive concrete may be the best grounding electrode encasement material for use in shallow topsoil environments, since the conductive concrete would not require a covering of topsoil for protection.

4. Installation of ground plates along the length of the ground rings instead of vertical ground rods. The ground plates should be encased in a grounding electrode encasement material.

5. Installation of a grounding electrode grid system, using ground plates instead of vertical ground rods. The grounding conductors and ground plates shall be buried as deep as the soil will allow. The grounding conductors should be encased in a grounding electrode encasement material. A conductive concrete may be the best grounding electrode encasement material for use in shallow topsoil environments, since the conductive concrete would not require a covering of topsoil for protection.

6. Installation of electrolytic ground rod systems. 7. Installation of building radial grounding conductors in a trench extending away from the building

at each corner. The radial grounding conductors shall be buried as deep as the soil will allow. The radial grounding conductors shall bond to the building ground ring using exothermic welding or listed irreversible high-compression fittings. The radial grounding conductors should be encased in a grounding electrode encasement material. A conductive concrete may be the best grounding electrode encasement material for use in shallow topsoil environments, since the conductive concrete would not require a covering of topsoil for protection. Each radial grounding conductor may have ground plates installed every 6 to 16 feet along its length.


8. Installation of tower radial grounding conductors in a trench extending away from the tower and building. The radial grounding conductors shall be buried as deep as the soil will allow. The radial grounding conductors shall bond to the tower ground ring using exothermic welding or listed irreversible high-compression fittings. The radial grounding conductors should be encased in a grounding electrode encasement material. A conductive concrete may be the best grounding electrode encasement material for use in shallow topsoil environments, since the conductive concrete would not require a covering of topsoil for protection. Each radial grounding conductor may have ground plates installed every 6 to 16 feet along its length.

3.7 GROUNDING IN ARCTIC REGIONS

A. It may be difficult to achieve an effective low resistance grounding electrode system at sites located in arctic regions (or similar cold climates). In these cases, consultation with an engineering firm is recommended. The primary issue with achieving an effective grounding electrode system in arctic regions is making good contact with frozen high-resistivity soils. Where frozen high-resistivity soils are encountered, optimum grounding can only be accomplished by special attention to both surface and subsurface terrain. The resistivity of frozen soils can be 10 to 100 times greater than in the unfrozen state; therefore, seasonal changes in temperature and moisture greatly affect the resistance to earth of the grounding electrode system.

B. Seasonal freezing accounts for an increase in grounding electrode system resistance. If frozen soil has a high resistivity, then providing larger electrodes reduces the resistance to earth. In arctic areas that generally have very shallow surface thaw layers, horizontal rods or conductors may be easier to install than driven rods and provide an equivalent resistance to earth. Whether to install multiple electrodes, or a single deep-driven rod, or horizontal conductors is usually dependent on soil conditions at the site and the economics of installation.

C. An option for an effective grounding electrode system may be to install electrolytic ground rods that are encased in a grounding electrode encasement material.

3.8 GROUNDING ELECTRODE SYSTEMS COVERED BY CONCRETE OR ASPHALT

A. When installing a grounding electrode system, every attempt should be made to ensure that the surface area above the grounding electrode system is not covered with concrete or asphalt. Areas covered with concrete or asphalt will dry out over time, therefore increasing the resistance to earth of the grounding electrode system. Some alternatives to covering the area with concrete and asphalt are listed below: 1. Cover the area with gravel. 2. Landscape the area. 3. Use electrolytic ground rods when the area must be covered with concrete or asphalt.



SECTION 33 79 84 INTERNAL GROUNDING AND BONDING CONDUCTORS

PART 1: GENERAL

1.1 SUMMARY

A. Proper bonding and grounding of equipment is essential for personnel safety and system reliability. Because of the increase in circuit density and the advent of lower-voltage integrated circuit devices, communications systems equipment is now more vulnerable than ever to damage resulting from lightning activity and power line anomalies. Inadequate or improper equipment bonding and grounding can permit a difference of ground potential to exist between system components, which may result in injury to personnel, system failure, and equipment damage.

B. An internal grounding system shall have low electrical impedance, with conductors large enough to withstand high fault currents. The lower the grounding system impedance, the more effectively the grounding electrode system can dissipate high-energy impulses into the earth.

C. This specification covers general requirements for grounding and bonding conductor types, sizes and bonding methods for electrical equipment, radio facility equipment and ancillary devices.

D. All components of the internal grounding system and all equipment and ancillary support apparatus shall be effectively bonded together by using the requirements and connection methods described within this Section.

PART 3: EXECUTION

3.1 GENERAL INSTALLATION OF INTERNAL GROUNDING AND BONDING CONDUCTORS

A. All grounding conductors shall be installed and routed so that personal safety is not compromised and that all equipment is serviceable. The following requirements shall apply:

1. Length: conductors shall be no longer than required to achieve their purpose and shall be installed and routed in a professional and skillful manner.

b. Conductors shall be routed toward the MGB, SSGB, or RGB. Connections to bus conductors shall always be made with the tap conductors routed toward the MGB, SSGB, or RGB.

c. At points where conductors must pass through a hole in a metallic surface and the hole is slightly larger than the conductor, the conductor shall be bonded to the metallic surface through which it passes. If the hole or opening is much larger than the conductor and is intended to accommodate several conductors, the conductor is not required to be bonded.

d. Ground bus conductors may be routed within cable trays, on the outside of cable trays where suitable support is provided, or along equipment platforms.

e. Equipment grounding conductors shall be installed along the rack rail or other suitable support medium leading to the cable tray system or ground bus conductor.

Grounding conductors may come in contact with other cable groups if they cross at a 90-degree angle and the crossing angle can be maintained. An exception may be when conductors are grouped together to enter or exit a cabinet or enclosure. Grouping only at this point is acceptable, provided the conductors are suitably separated on either side of the opening.

2. To minimize potential inductive effects when routing a grounding conductor through ferrous material, the conductor shall be separated from the ferrous material by a distance of at least two inches where achievable, or the grounding conductor shall be effectively bonded to the ferrous material.

3.2 INSTALLATION OF INTERNAL PERIMETER GROUND BUS CONDUCTORS

The series or daisy chain method refers to any method of connection whereby the conductors are connected from one chassis, equipment frame or rack connection point to a second chassis, equipment frame or rack connection point and on to a third connection point, creating a series arrangement whereby the removal of the second connection point interrupts the ground path from the first chassis, equipment frame or rack.

7. When bonding two conductors together, or bonding a conductor to a lug, connections shall not depend solely on solder although properly crimped connections may be soldered.

8. Mechanical lugs and clamps (such as set screw lug or clamp) shall not be used on solid conductors.

9. Conductors shall not extend through or beyond the clamp, fitting, or lug unless the device is designed and listed to permit this conductor extension.
