For fully automated 3-phase transformer testing
Switch Box CP SB1: Automated – Safe – Comfortable
The transformer switch box CP SB1 is an accessory to the CPC 100. Testing of power transformers over all taps and all phases is fully automated. Results are recorded in the CPC 100 with the ratio and tap changer test cards, and can be analyzed with the PC tool set.
Features & Benefits
The CP SB1
- Saves time by reducing wiring work to a minimum and quickly discharging the transformer
- Removes the need for rewiring
- Increases safety by reducing the risk of accidents
- Minimizes the likelihood of measurement errors – the CP SB1 allows performing the ratio and winding resistance tests automatically by simply choosing the correct vector group
- Users are able to verify the vector group of the transformer with the ratio measurement
- Measurements for special applications are possible in manual operation mode (e.g., for auto-transformer tests)
Applications
- Transformer ratio measuring support
- Winding resistance measuring support
- Verification support for correct operation of the tap changer
- Multiplexing of the high voltage output and the 6 A DC output of the CPC 100 to all three phases of a power transformer
- Multiplexing of measured voltages from the transformer to the V1 AC input / V DC input of the CPC 100
- Operation of the tap changer, so that measurements can be performed over all taps and all three phases without the need for direct user interaction
- Automated fast discharge process of the transformer in-between phase switches and after measurements
