China Voltage Transformer Tester Portable Voltage Transformer Tester Transformer Tester

CT/PT TESTERGF106 Portable PT Voltage transformer tester is mainly used for field testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. Adopt LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data, with simple and convenient operation.Features
Steady and transient state characteristic tests of various types of CT/PT
The use of advanced power technology, the test knee point reaches up to 40kV
No external other auxiliary equipment, stand-alone to complete all test items
CT test, easy to test, all the tests are using the same wire connection except the load test
It carries with thermal printer, so it can print test results on site
Parameters such as knee point current and voltage
Parameters such as 10% error curve, 5% error curve
The device can store 3000 groups of test data which would not be lost if the device is power off.
The data can be displayed and analyzed after the test, or transferred to PC through USB disk and produce a Word file report
