Ross Engineering’s Hipot Control Unit features Variable Voltage Control
with safety return to zero. It provides adjustable current overload
trip, a 4½ digit 0-50kV, 0-60kV or 0-100kV RMS digital voltmeter for
easy viewing and a 0-20mA 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.
Total 50kV system weight is 76 lbs for epoxy potted transformer
portability. Total 60kV and 100kV system weight is approximately 850
lbs. Shipping crate adds approximately 100 lbs. The 800 lbs Hipot
Transformer is oil filled. Total shipping weight is approximately 950
lbs.
The secondary of the transformer is provided with a control winding
which permits monitoring of high voltage output up to 50kV, 60kV or
100kV depending on model.
The basic HV Transformer rating is 20mA. Maximum continuous Hipot output
current is limited by the control unit to approximately 10mA with
current limiting resistors and overload sensing of 0.7 to 10mA. A
special control unit is required if higher AC output current is desired
for high capacitance loads to 20mA or more and for HV Vacuum
Interrupters or other devices.
