SATEC presents a new model of the PM174/5 Advanced Power Quality Analyzers, designed to interface with ABB’s KEVA/KECA/KEVCY medium voltage sensors.
These unique sensors feature built-in potential transformer and current transducer combined, integrated into a RJ45 3VAC output, originally designated for interfacing digital protection relays.
SATEC’s concept utilizes this interface to piggyback on these existing sensors and their output for highly accurate power metering. By standard, readings provided by protection equipment do not come near the PM174/5’s accuracy and do not provide a power quality profile of the network.
Adopting this concept also saves considerably on the need for erecting extra expensive metering cubicles, with all involved equipment (MV CT and PT).
