ENMV-3

ENMV-3 measures direct voltage and current in generator excitation circuits at power plants, and integrates into WAMS supplementing phasor measurement data.

An external ENCS time sync module synchronizes the internal clock of ENMV-3 via IRIG-A. ENMV-3 uses IEEE C37.118.2 communication protocol for measurement data transmission. Available communications are two Ethernet 100Base-TX.
