Fully automated 3-phase transformer testing measurements of ratio, winding resistance and the tap changer became a reality with the CP SB1. As an accessory to the CPC 100, testing of power transformers over all taps and phases is fully automated. Time-consuming rewiring in between measurements can be avoided.

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.

Operation: Front of CPC 100 or PTM software

Operating temperature range: 0 °C … +35 °C Nominal temperature range: 18 °C … +28 °C Storage temperature range: -30 °C … +60 °C

Measurements: Dimensions: 240 mm (W) x 220 mm (D) x 90 mm ( H )

Weight: 25 kg with accessories


Key Features

  • Multiplexes the CPC 100 outputs to all phases of a power transformer and vice versa
