Power Reading Verification

Step 1:
Use the same voltage connections as in the previous test, polarity voltage jumpered to C13, 14,
and 15, neutral tied to C16. Use the same current connection as in Steps 3 and 4 of Current
Circuit Verification, CT Circuit 1; that is, polarity current in D1 out D8 with D2 and D3, D4 and
D5, D6 and D7 jumpered together. Note: For protection systems equipped with two sets of CTs,
be sure that CT1 is selected for the Bus CT Selection setting found on the System Parameters,
Sensing Transformers screen in BESTCOMSPlus.
Power readings in this procedure are based on a 5 amp BE1-11g; for
1 amp values, divide by 5.
Step 2:
Apply 100 volts at angle 0 degrees and 5 amps to the BE1-11g. Verify the accuracy of the
power reading by using the Metering Explorer in BESTCOMSPlus to open the Analog Metering,
Power screen. Power should be 1.5 kW ±1.0% and reactive should read near 0 vars. The
Metering > Analog Metering > Power/Watts > Vars screen of the front-panel display can also be
monitored to verify power and reactive readings. The apparent power should be 1.5 kVA ±1.0%
at unity power factor. The Metering > Analog Metering > Power > VA/PF screen of the front-
panel display can also be monitored to verify apparent power.
Step 3:
Reverse the current polarity and apply the same values as in Step 2. Note that the power
reading is –1.5 kW, which indicates "power in" to the zone being protected.
Step 4:
Return the current polarity back to Step 1 position. Apply 100 volts at angle 0 degrees and
5 amps at angle –90 degrees (I lags E by 90°) to the BE1-11g, and verify reactive power
accuracy by using the Metering Explorer in BESTCOMSPlus to open the Analog Metering,
Power screen. Power should be nearly 0 kW, and reactive should read 1.5 kvar ±1.0%. The
Metering > Analog Metering > Power screen of the front-panel display can also be monitored to
verify power and reactive values. Note power factor reads near 0 with a negative sign indicating
a lagging power factor angle.
Step 5:
Reverse the current polarity and apply the same values as in Step 4. Note that the reactive
power reading is –1.5 kvar, which indicates reactive power in to the device being protected.
Also note that the power factor angle is a positive value near zero. A positive power factor angle
indicates leading power factor.
Step 6:
Repeat Steps 2 and 4 for current values of 10 and 20 amps. Corresponding power reading
should be 3 kW/kvar and 6 kW/kvar ±1.0%.

Auxiliary Voltage Input Verification - VX and VX 3
