Audited Supplier GDVA-405 Portable Current Transformer Tester CT PT Test Set
CTs and PTs are used to measure and transform electrical currents and voltages in power systems to levels suitable for measurement and protection purposes. It is crucial to ensure the accuracy and reliability of these transformers to maintain the overall integrity of the power system.
A transformer CT/PT tester is designed to perform various tests to assess the performance of CTs and PTs.
Tests for Current Transformer: Tests for Potential Transformer:
1. Excitation curve and parameters test 1. Turns ratio test
2. Turns ratio test 2. Ratio error and phase angle error test
3. Ratio and phase error test 3. Polarity test
4. Polarity mark check 4. Secondary burden test
5. Winding resistance measurement 5. Winding resistance test
6. Secondary loop burden measurement
7. Error line curve test for protection CT
8. Transient CT parameters test
9. CT nameplate guess
10. Saturation hysteresis loop curve measurement
