CMC CT-Check
Functional CT Checks with the CMC 500
Functional CT Checks with the CMC 500
CMC CT-Check extends the versatile CMC 500 with automated basic checks of current transformers (CTs). It supports commissioning and maintenance tasks.
You perform the following commissioning-relevant checks:
- Voltage-based ratio
- Polarity check
- Winding resistance (temperature corrected)
- Knee-point voltage (Up to 2.5kV and according to IEC 61869-2)
- Operating burden
After testing, the CT is automatically demagnetized. This helps you quickly detect polarity, ratio, core connection, burden, or remanence issues.
Reduce CT-Related Commissioning Risks
Detect CT, burden and wiring related issues during commissioning that frequently arise from:
- Incorrect core connection
- Polarity inversion
- Undocumented burden changes
- Residual magnetization
Integrated within CMC 500, it helps increase reliability of the protection system.
- One test set for comprehensive relay and functional CT tests
- Minimal rewiring with guided steps
- Generate a one-page report
