Data Sheet
Vanguard TRM-403
  • Performs three phase testing 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
Data Sheet
Vanguard TSB
  • The TSB, or Trip Saver Box, is best suited for those situations where a bucket truck is required to connect test cables to transformer bushings for performing Winding resistance and transformer ratio tests
  • The TSB is compatible with all Vanguard 3-phase TTR instruments and TRM-203/403 winding resistance meters.
