CE Approved Transformer CT PT Testing Equipment CT PT Tester
Testing Items:
1. Turns ratio testing: Measuring the turns ratio of current transformers (CT) and potential transformers (PT), which is the ratio between the input signal and the output signal.
2. Phase angle testing: Measuring the phase difference between the input signal and the output signal to assess the phase accuracy of CTs and PTs.
3. Vector error testing: Evaluating the difference between the output and theoretical output of CTs and PTs to determine their vector error.
4. Frequency response testing: Checking the response characteristics of CTs and PTs at different frequencies to ensure accuracy and stability across different frequency ranges.
5. Load characteristic testing: Testing the output performance of CTs and PTs under different load conditions to verify their load adaptability and stability.
6. Insulation resistance testing: Evaluating the insulation performance of CTs and PTs, including measurement and assessment of insulation resistance.
7. Zero-sequence current testing: Measuring the response of CTs to zero-sequence currents to assess their capability to detect zero-sequence faults.
8. Withstand voltage testing: Conducting high-voltage withstand tests to verify the insulation strength and tolerance of CTs and PTs.
