CP SB1

Switch box for fully automatic testing of three-phase power transformers

Simplified and safer testing

The CP SB1 is an accessory for the CPC 100 and simplifies measurement of three-phase power transformers.

The switchbox CP SB1 reduces wiring work at power transformers. Thereby, the time needed for testing can be reduced and, at the same time, safety can be significantly increased.

The transformer ratio and winding resistance are automatically measured in all three phases (in sequence) in all tap changer positions. The measurement results are recorded by the CPC 100 and can be analysed with the accompanying software package.

Key features

  • Time saving: Rewiring no longer necessary
  • Safety: one-time connection of cables
  • Minimization of measurement errors: Fully automated testing
  •  

  • For every tap changer position the transformer ratio and winding resistance can be measured
  •
