ENIP-2, manual, ENIP.411187.002. Rev. 11.2020
18
ENIP-2 is not certificated as energy meter, nevertheless, its accuracy class is 0.2S (energy
measurement error for 0.01I
rated
is 0.35%, and for I
rated
–
0.001%).
3.2.2
ENIP-2 (PMU) supports phasor measurement as defined by IEEE C37.118. Data rate up to
100 frames per second.
