CP SB1

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

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

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 analyzed 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

Applications

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