Omicron CP-SB1 3-Phase Switchbox

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.

The CP SB1 is a transformer switch box designated for automatically measuring
the ratio and winding resistance, and testing the tap changer of three-phase
power transformers. It is an accessory to the CPC 100. Automatic control of the
On-Load Tap Changer (OLTC) is included. Testing of power transformers over
all taps and all phases is fully automated. Therefore, no rewiring is required.

The CP SB1 is controlled from the CPC 100 via its serial interface. The results are
recorded in the CPC 100 with the ratio and tap changer test cards, and can be
analyzed with the computer tool set (CPC 100 Excel File Loader).
