The EPC (Electrical Phenomena Cluster) is SmartSenseCom’s core grid monitoring system for revenue-grade power flow measurements and relay protection in high and medium voltage networks. Each EPC system measures current, voltage, and conductor temperature with extremely high accuracy and at speeds well within one cycle on both AC and DC systems. The EPC has none of the inherent safety issues associated with typical CT’s and PT’s. The optical sensors measure fields without being electrically coupled to the primary circuit, they do not require ground connections, they have no polarity, and there is no risk of an open secondary. These systems also do not require any oil or SF6 for insulation.

Advantages Intensity Modulated Optical Measurements offer numerous advantages as compared to typical CT’s and PT’s § Exceeds .15 Class metering grade accuracy at all levels of

voltage and current – <0.1% ratio error from 0V – 4x Vn – <0.1% ratio error from 0.5% In – 20x In – <.053° phase error – Full wave form reproduction through entire operating

range § Highly reliable and stable with no temperature or EMI

sensitivity § Explosion proof design § 100% remote calibration § Secondaries and related safety concerns are eliminated § Maintenance free. No oil or gas required. The integration of current and voltage measurements in one field device provides additional benefits in terms of § Cost of the equipment § Space required § Packaging dimensions § Time for erection/commissioning § Cables for interconnection § Foundations and structures This combination of stable optical measurements and physical optimization creates a high performance instrument that delivers significantly more accurate, relay and meter ready information within a 50/60 Hz cycle or DC environment. All delivered at a cost that is less than any CT/PT instrument in its class.

EPC Optical Power Monitoring System

Description The EPC system consists of one to three field devices depending on system configuration, the Smart Controller, and fiber optic cable. The EPC system is equally effective in high voltage AC and DC systems and medium voltage AC systems. Technical features § Suitable for both metering and protection § Relay signal available in less than 50 µsec § Current and voltage measurements to the 64th harmonic § Exceeds 30 year life § Completely passive in the switch yard. All electronics

remotely located in the control hut. § Wide area communications ready. Ideal for use with

synchrophasors and other network management systems

Smart Controller

SSC 8-channel Smart Controller (chassis-mount or stand-alone)

Advantages & Features SSC’s Smart Controller consolidates electro-optics, analog-to-digital conversion, data acquisition and initial analytic processing into a single unit. The 8-channel card can be chassis-mounted for high-channel count applications. The Smart Controller is common to all SSC optical measurement systems, regardless of application, and provides a number of unique advantages: § Extremely fast – Provides processed digital output of

basic information in ≤ 50 microseconds and full phasor measurement in ≤ 85 microseconds, enabling sub-cycle control

§ Wide-area synchronous measurement – Uses both external (e.g., GPS) and internal network clocks to maintain synchronous measurement, similar to the timing architectures used in telecommunications networks

§ High sampling rate – Simultaneous 50 ksps base rate up to 2.3 Msps per channel

§ 130 dB signal above noise in processed signal – Up to 40 dB more than most commercial systems, vital to achieving speed, accuracy and dynamic range of optical sensor system

§ Onboard processing – Reduces data transmission requirements, drives alarming and generates command signals for automated control

§ Communications agnostic – Digital output compatible with most communications system architectures

§ Secure – Meets U.S. Department of Defense cybersecurity specifications to include FIPS 140-2 compliance and Common Criteria EAL2 certification

§ System management – Utilizes syslog standards for access control and system monitoring and SNMP.V3 for alarms and sensor diagnostics

§ Very low system noise – Designed to minimize electronic and optical noise, maintaining a low, flat noise floor across the entire measurement range

§ Low power performance – A little more than 2W per channel including sensor and electronics
