 VAN-TRM-403 Three Phase 40A Winding Resistance Meter with AutoDemagnetization

The TRM-403 is a three phase transformer winding resistance meter that allow
the user to connect all test cables to the transformer bushings. The unit will
then measure the transformer resistance value for each of the phases without
the need to disconnect and reconnect cables for each phase. The TRM-403 can
provide a fast and stable reading of very large transformers by utilizing a
60Vdc power supply. It is capable of outputting a selectable test current from
1A to 40A. Since the TRM-403 can accurately measure resistance from 1
micro-ohm to 500 Ohms, it can be used as a micro-ohm meter to measure EHV
circuit breaker contact resistance, or for any low resistance measuring
application.

RESISTANCE READING RANGE 1 micro-ohm to 500 Ohms
ACCURACY 1-19,999 micro-ohms: +/-0.5% reading, +/-1 count
20-999 milliohms: =/-1% reading, +/-1 count
1-2000 Ohms: +/-1.5% reading, +/-1 count
TEST CURRENT 1-40A in 1A increments
TEST VOLTAGE 60 Vdc charging, 18V DC max during measurement
INPUT CHANNELS 4 input channels for measuring resistance
