12
New DLRO10HD – Applications
During electrical manufacturing processes• Testing switches, connectors and relays
–To ensure contact resistance is within specified values.
• Cable resistance
–Too low means too much copper in cable (higher costs), too high means not enough copper (cables’ current carrying capacity compromised)
• Motors
–To determine heat rise under load, measure winding resistance, check for short circuits or open circuits.
• Generators
–To determine heat rise under load, measure winding resistance, check for short circuits or open circuits.
13
New DLRO10HD – Applications
During electrical manufacturing processes• Fuses
–To ensure resistance is within specified values.
• Cable looms
–Checking bonding and interconnections when installing in equipment, racks etc.
• UPS / Car batteries
–Carrier to plate weld resistance, High resistance indicates poor weld quality that will restrict battery’s ability to carry current.
14
New DLRO10HD – Applications
Aircraft assembly and maintenance• Main frame electrical and mechanical bonds – to ensure a stable
“ground plan” to protect aircraft from static electricity and lightning strikes.
–Static wick bonding
–Antenna bonds
–Control linkage bonding
–Battery connection and interconnection
– Integrity of structure and exhaust system
–Metallic coating resistance
15
New DLRO10HD – Applications
Railway / Railroad Industry• Strap and wire bond between rail segments – maintaining
performance of control and telephone system. Minimising power loss on three rail systems. However sometime higher test currents are specified.
• Cable joints – power system efficiency.
• Earth / ground bonds – e.g. lightning protection on structures. Ground mats, ground conductor rings, metal cladding, metal ceilings, metal floors, hand rails, seats etc. to limit step and touch potential.
• Platform edge doors – Earth / ground bonding (mainly underground systems)
16
New DLRO10HD – Applications
Aluminium refineries• Graphite electrodes – to verify density
Ship building or any metal structures• Weld quality – measure at regular intervals along weld length
looking for uniformity.
• Installed equipment bonds – to steel structure / hull.
Raw material processing, e.g. cement plants• Power carrying elements – installation and maintenance
• Ground bonds - cement is corrosive
Automotive industry• Cable leads in robot spot welders work-harden through flexing
causing strands to break. Results in poor weld quality.
17
New DLRO10HD – Applications
Power Generation and Distribution• Bus bars – lap joint tests to maintain low resistance, and hence
maintaining efficiency and reducing likely hood of fire.• Cable joints – including overhead lines. High impedance joint
can explode.• Fuses – connections
Uninterruptible Power Supply (UPS)• Battery straps – quality of connections. Preventing potential of
fire and failure to operate• Carrier to plate weld resistance – High resistance indicates poor
weld quality that will restrict battery’s ability to carry current. Military vehicles – Trucks, tanks etc.
• Installed equipment such as radio equipment - ground bonding to vehicle chassis.
18
New DLRO10HD – Applications
Buildings – wiring, lightning protection bonds• Various bond, both for power distribution and earth grounding –
check for step and touch voltage safety in fault condition.
• Conduit continuity – metal conduit, detect corroded or loose threads etc.
Pipe lines• Cathodic protection – check connection etc. Tough environment
ideal for the DLRO10HD
Wind turbines• Lightning protection – wing tip to base, or component parts in
manufacture. Long test leads available for this application.
• Earth ground bonds – various
