ENIP-2 PMU

ENIP-2 synchronized phasor measurement unit (PMU) devices calculate the vectors of currents and voltages of the fundamental harmonic. The signal processing algorithms comply with IEEE C37.118.1 and are configured for class P (Protection) or M (Measurement).

For correct operation, the internal clock of the PMU must be synchronized with a single time source — from an external (ENCS-2 via RS-485 IRIG-A/B) or an integrated receiver using signals from global navigation systems GLONASS/GPS or from the facility's local network using the IEEE 1588v2 PTP protocol.

Measurements are displayed on a color touchscreen display in tabular form, on a vector diagram, or as an oscilloscope.

There are two types of PMU available for order: with transformer connection to measuring circuits and with digital inputs according to IEC 61850-9-2.
