NOTE:
ALL ANGLES INDICATED ARE LAGGING ANGLES
ALL VALUES OBTAINED IN THIS TEST MUST BE THE ONES CORRESPONDING TO THE PHASOR ONES
Apply the following voltage and frequency values to the relay:
Verify that the relay measures the values with an error of ±1 % of the applied value from 10V to 208V.
Apply the following current and frequency values to the relay:
Verify that the relay measures the values with an error lower than ±0.5% of the test value or ± 10 mA, whichever is greater,
for phases and ground.
Verify that the relay measures the values with an error lower than ±1.5% of the test value or ± 1 mA, whichever is greater,
for sensitive ground (SG).
