CT PT Volt-ampere Characteristics Tester , Multifunctional CT PT Testing
I. Product Description:
With the increase requirement of relay protection, the test and check of v-c characteristic carve and the 10% error carve of instrument transformer have became more and more attracting by power system. Based on the absorbing of customers’ suggestion, Fanke has developed a new FKFA voltage-current characteristic comprehensive tester. It adopts high-speed SCM control and inset voltage-up machine, it can test CT voltage-current characteristic, 10% error curve, transformation ratio and polarity on spot. With a special voltage-up transformer, it can do a current-voltage characteristic test for CT/PT within the voltage of 500kV and the current of 1A.
