4.6 Disabling the H Voltage Checking Feature
The EZCT-2000C's H Voltage input can only handle voltage up to 100 Vac. When a saturation
test is being performed, the unit monitors the H voltage and stops the saturation test if a
voltage above 100 Vac is detected. In certain noisy substation environments, the unit may pick
up a noise spike which may be interpreted as high voltage input to the H terminal, causing the
unit to stop the saturation test. For such cases, it may be necessary to disable the H Voltage
monitoring feature so that a saturation test can be properly completed. Follow the steps below
to disable the H Voltage checking features:
WARNING
If this feature is disabled and an actual over-voltage situation exists (voltage over
100 Vac), it will NOT be detected by the EZCT-2000C and can cause damage to the
unit. This feature should be disabled only after confirming that an actual over-
voltage situation does not exist.
