current measurements can also be verified on the Metering > Analog Metering > Current >
Current Circuit 2 > Secondary Current screen of the front-panel display.
Step 3: To verify IA2, IB2, IC2, and IG2, connect the four current inputs in series by connecting suitably
sized jumper wires between terminals F2 and F3, F4 and F5, and F6 and F7. Then connect an
ac current source to terminals F1 and F8.
Step 4: Apply the appropriate current values in Table 102 to the BE1-11t. Verify current measuring
accuracy on the Analog Metering, Current, CT Circuit 2, Secondary Current screen inside the
Metering Explorer of BESTCOMSPlus. IA2, IB2, IC2, and IG2 current measurements can also
be verified on the Metering > Analog Metering > Current > Current Circuit 2 > Secondary
Current screen of the front-panel display.
Step 5: Leave current circuit connected and de-energized. These test connections will be used later
when verifying power readings.
Three-Phase Voltage Circuit Verification
Step 1: Connect an ac voltage source at nominal frequency between BE1-11t Terminals C13 (A-phase)
and C16 (Neutral terminal). Apply 100 volts and verify voltage-measuring accuracy by using the
Metering Explorer in BESTCOMSPlus to open the Analog Metering, Secondary Voltage screen.
Readings should be: VA = 100 volts
±0.5%, VAB = 100 volts ±0.5%, VCA = 100 volts ±0.5%,
3V0 = 100 volts
±0.75%, V1 = 33.4 volts ±0.75% (applied divided by 3), and V2 = 33.4 volts
±0.75% (applied divided by 3). The Metering > Analog Metering > Voltage > Secondary Voltage
screen of the front-panel display can also be monitored to verify voltage measurements.
Step 2: Connect an ac voltage source at nominal frequency between BE1-11t Terminals C14 (B-phase)
and C16 (Neutral Terminal). Apply 100 volts and verify voltage-measuring accuracy by using
the Metering Explorer in BESTCOMSPlus to open the Analog Metering, Voltage, Secondary
Voltage screen. Readings should be: VB = 100 volts
±0.5%, VAB = 100 volts ±0.5%, VBC = 100
volts
±0.5%, 3V0 = 100 volts ±0.75%, V1 = 33.4 volts ±0.75% (applied divided by 3), and V2 =
33.4 volts
±0.75% (applied divided by 3). The Metering > Analog Metering > Voltage >
Secondary Voltage screen of the front-panel display can also be monitored to verify voltage
measurements.
Step 3: Connect an ac voltage source at nominal frequency between BE1-11t Terminals C15 (C-phase)
and C16 (Neutral Terminal). Apply 100 volts and verify voltage-measuring accuracy by using
the Metering Explorer in BESTCOMSPlus to open the Analog Metering, Voltage, Secondary
Voltage screen. Readings should be: VC = 100 volts
±0.5%, VBC = 100 volts ±0.5%, VCA = 100
volts
±0.5%, 3V0 = 100 volts ±0.75%, V1 = 33.4 volts ±0.75% (applied divided by 3), and V2 =
33.4 volts
±0.75% (applied divided by 3). The Metering > Analog Metering > Voltage >
Secondary Voltage screen of the front-panel display can also be monitored to verify voltage
measurements.
Step 4: Connect BE1-11t Terminals C13 (A-phase), C14 (B-phase), and C15 (C-phase) together.
Connect an ac voltage source at nominal frequency to the three jumpered terminals and the
Neutral Terminal (C16).
Step 5: Apply the voltage values listed in Table 103 and verify voltage-measuring accuracy by using the
Metering Explorer in BESTCOMSPlus to open the Analog Metering, Voltage, Secondary
Voltage screen. The Metering > Analog Metering > Voltage > Secondary Voltage screen of the
front-panel display can also be monitored to verify voltage measurements.
