CT/PT TESTING
Current & Voltage Transformers are integral part of Power System as they provide Inputs for Metering & Protection devices. Testing Services are conducted using highly advance State of Art CT/PT analyzer with accuracy of 0.1% for all types of CT/PT ( ie Protection of Metering Class) . After Test automatic software generated reports with time stamping are submitted .
Tests for Current Transformer:
- Excitation curve and parameters test
- Turns ratio test
- Ratio and phase error test
- Polarity mark check
- Winding resistance measurement
- Secondary loop burden measurement
- Error line curve test for protection CT
- Transient CT parameters test
- CT nameplate guess
- Saturation hysteresis loop curve measurement
Tests for Voltage Transformer:
- Turns ratio and phase angle error test
- Polarity test
- Secondary burden test
- Winding resistance test
