Description

Descriptions

PCT200Ai is the CT/PT test set can finish various tests of different transformers. Compared with PCT200i, its accuracy is higher. This CT analyzer can test the 0.2s class CT. Only this CT analyzer - the high-accuracy transformer tester has passed the tests held by Wuhan High Voltage Research Institute. The max permissible error of ratio measurement is ±0.05% and max phase measurement is ±2min.
