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

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.

omicron CP SB1

The CP SB1 is an accessory for the CPC 100 and simplifies measurement of three-phase power transformers
Time saving: Rewiring no longer necessary
Safety: one-time connection of cables
Minimization of measurement errors: Fully automated testing
