GF106T ct testing using mutual inductor
It is mainly used for field testing of P class CT and PT. The test items mainly include excitation characteristic, transformation ratio, polarity, degauss, 5% and 10% error curves, secondary circuit check, withstand test of power frequency alternating current and secondary load. Adopting LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data, with simple and convenient operation.

Functions
1. Steady and transient state characteristic tests of various types of CT/PT.
2. The use of advanced power technology, the test knee point reaches up to 10kV.
3. No external other auxiliary equipment, stand-alone to complete all test items.
4. CT test, easy to test, all the tests are using the same wire connection except the load test.
5. It carries with it thermal printer, so it can print test results on site.
6. Parameters such as knee point current and voltage.
7. Parameters such as 10% error curve, 5% error curve.
8. The device can store 3000 groups of test data which would not be lost if the device loses its power.
9. The data can be displayed and analyzed after the test, or transferred to PC through USB disk and produce a Word file report.
10. Portability: weight <12Kg.
