6.7VERIFICATION OF MEASUREMENT
Set the relay as follows
NOTE:
ALL ANGLES INDICATED ARE LAGGING ANGLES
ALL VALUES OBTAINED IN THIS TEST MUST BE THE ONES CORRESPONDING TO THE PHASOR ONES
6.7.1 VOLTAGES
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 plus 0,1% of full scale (275V).
6.7.2 PHASE CURRENTS
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).
