Frequency Measurement; Recloser - GE SMOR-B GEK 105593C Instructions Manual

PHASE CURRENTS
• Inject the following current values into the relay:
I (Amp) Angle
Ia
Ib 165
Ic 285
(In is the nominal or rated current for the relay phase current inputs, 5 or 1 Amp)
• Check that the relay measures Ia, Ib, Ic with an accuracy of at least 5%.
• Repeat the test for 60 Hz.
GROUND CURRENTS
• Inject the following current values into the relay:
I (Amp) Angle
Iground
(In is the nominal or rated current for the relay ground current input, 5 or 1 Amp)
•
Check that the relay measures Iground with an accuracy of at least 5%.
•
Repeat the test for 60 Hz.
• Apply 110V at 50 Hz through the voltage input corresponding to phase B.
• Check that the frequency measured by the relay is inside the range of 49.97 and 50.03 Hz.
NOTE : Check that the inhibition voltage of the frequency units is lower than the applied voltage. If not, the
unit does not measure the frequency.
