Feature：

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 40kV.

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 ?le report.

10.Portability: weight <12Kg
