      TRM-403

      Transformer Resistance Meter


      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.

      • Perform three phase test on a transformer without the need to switch cables
      • Can provide individual Delta winding resistance values
      • Can provide individual Wye (with no neutral) winding resistance values
      • Demagnetize transformer after test
      • Selectable test current from 1A to 40A
      • Computer control via RS-232C, USB, or Bluetooth interface
      • Built-in 2.5" wide thermal printer
