OPERATIONAL VERIFICATION PROCEDURE
14. Move short from 36 kV output to 130 kV output and ground. Set Measurement Divider Switch to 36 kV /
180 mA. Repeat step 13. Unit should trip off at approximately 4.6 mA.
NOTE: Do not attempt to check 110% level of current trip under shorted output conditions. Rated output
currents are only available through a capacitive load of sufficient value. Shorted current values should never
exceed 50% of rated currents for the High Voltage Tap being used. If desired to test at 110% of current rating,
the 36kV/180mA tap must be connected to a High Voltage Capacitor of approximately 15 to 20 nanofarads
rated at 36 kVAC or higher.
15. Turn Off Main Power Circuit Breaker on Controls.
END OF OPERATIONAL VERIFICATION TEST!
