Digital CT PT TESTER, For Industrial
CT/PT TESTER is mainly used for field testing of P class CT and PT. There is facilities to conduct excitation characteristic test , ratio test , polarity test. It can plot 5ï¼… and 10ï¼… error curves. There is a provision of secondary circuit check, withstand test of 50 Hz ac and secondary load test. The test menu and results are displayed on LCD . The tester is equipped with a mini printer to facilitate printing the result on the field. USB port is provided to save the data. The tester is very simple and easy to operate.
For testing CT following test functions are available.
- Transformation ratio test
- Polarity test
- 5% and 10% error curve
- Power frequency Ac withstand test
- Automatically calclate excitation knee point value
- Magnetizaiton curve
- Primary current injection.
