Ross Engineering’s Hipot Control Unit features Variable Voltage Control
with safety return to zero. It provides adjustable current overload
trip, a 4½ digit digital voltmeter for easy viewing and a AC digital
milliammeter. Its simplified design is excellent for testing and
accurately calibrating high voltage instrumentation or measuring AC
insulation leakage current, and testing breakdown or withstand voltage
for any type of device where AC Hipot testing is appropriate within its
current limit.
Total 50kV system weight is 76 lbs for epoxy potted transformer
portability. Total 60kV and 100kV system weight is approximately 170 lbs
to 850 lbs. Shipping crate adds approximately 100 lbs. The larger Hipot
Transformers are oil filled. Total shipping weight is approximately 300
lbs to 950 lbs.
The secondary of the transformer is provided with a control winding or
voltage divider which permits monitoring of high voltage output up to
50kV, 60kV or 100kV even to 130kV RMS short time depending on model.
The basic HV Transformer rating is 5 to 25mA continuous, higher short
time. Maximum continuous Hipot output current is limited by the control
unit with current limiting resistors and adjustible overload sensing. A
special control unit is required if higher AC output current is desired
for high capacitance loads and for HV Vacuum Interrupters or other HV
Vacuum devices.
