10. Measurements and testing commissioning of high-voltage transformers(CT, VT)
Type of test
- Measuring ratio transformation of current transformers (CTs)
- Measurement of the ratio transformation of the TPs’ BUSHING TCs
- Checking of the polarity of the secondary CTs
- Measurement of the resistance of the secondary windings CTs
- Measurement of the resistance of the secondary circuits CTs
- Measurement of the secondary load CTs
- Measurement of the magnetization curve of CTs and angled point
- Measurement of the ratio transformation of CT Rogowski
- Insulation measurement of the CTs
- Measurement of the ratio transformation voltage-transformers (VTS )
- Check the polarity of the secondary of VTs
- Measurement of the resistance of the secondary windings VTs
- Measurement of the resistance of the secondary circuits VTs
- Measurement of the secondary charge of VTs
- Insulation measurement of the VTs
