6.
Push the TEST button. The HT-20KVPac will either:
Ramp the voltage at the rate set by the Ramp Time Procedure, if the Ramp Control
switch is set to ON.
Immediately energize the high voltage output if the Ramp Control Switch is set to
DEFEAT.
7.
If the Shutdown Limit switch is set to ON, and if the leakage current of the circuit under
test exceeds the alarm value, the Excess Leakage indicator will light and the test will
terminate.
If the Shutdown Limit switch is set to DEFEAT, and the requirements of Table 4-3 are met,
the HT-20KVPac will continue to test. Voltage output may sag if the power required by the
circuit is beyond the capabilities of the HT-20KVPac.
8.
If the Timer Control switch is set to ON, the HT-20KVPac will conduct the high voltage
test for the amount of time set in the Test Duration procedure.
If the Timer Control switch is set to DEFEAT, the high voltage test will continue only
while the TEST button is pressed.
9.
If an insulation system breakdown is detected, and
The Shutdown Limit switch is ON, the Hipot Fail indicator will light, the buzzer will
sound, the voltage will be removed.
The Shutdown Limit switch is set to DEFEAT, and the requirements of Table 4-3 are
met, the Hipot Fail indicator will light, and the test will continue as long as the TEST
button is pressed.
10.
If no breakdown is detected, the high voltage will be removed at the end of the test, the
Hipot Pass indicator will light, and the RESET button will light.
11. Do not disconnect the leads from the equipment being tested until test has ended, and the
voltage meter indicates zero volts.
Test Results
Hipot Pass:
If the Hipot Pass light is lit, the equipment being tested passed all test parameters.
Red Indicator/Buzzer:
Any red indicator/buzzer test result means the equipment being tested
failed a test phase. If unanticipated test failures continue, and you suspect that the equipment
under test is built correctly, check the following items:
