technology. It performs Resistance, DC High Potential and
Surge tests along with incorporating a supply monitor to

control and display module provides the user with
comprehensive testing results.
The Resistance Test verifies the existence of dead shorts
within the turn-to-turn coils, shows any imbalances between
phases due to turn count differences, along with locating
poor wire connections or contacts.
The DC high potential (HiPot) test is also done with the
D30R. Test voltage is set by the output control from 500
volts up to 30,000 volts. Current is displayed and an
overcurrent trip circuit monitors the test. If current exceeds
the trip level, the test is automatically halted. In its most
sensitive setting, the protective circuit will operate as low as
10 microamps.
The “Key Element” of the Surge test circuit is a grounded
grid hydrogen thyratron tube. The tube conducts very high
peak current (rated up to 20,000 amps). Such high
instantaneous currents are needed to fully test the very low
impedance windings of large motors or form wound coils.
This current is only produced for a few microseconds by the
discharge of a 0.1 microfarad capacitor.
Voltage rise time is 100-200 nanoseconds (0.1 - 0.2
