CT/PT Analyzer with Multi-ratio CT Testing

Model: CTP-120PA

The CT/PT Analyzer CTP-120PA is the revolutionary testing system for various CTs and PTs according to IEC and IEEE/ANSI standard. The Analyzer can automatically complete the test within seconds by one click of the patented multifunctional rotary mouse. It allows to test the knee-point voltage up to 40kV CTs and PTs on-site in power grids or in manufacturers' production facilities or test labs.

CT/PT Analyzer CTP-120PA is capable of testing multi-ratio CTs automatically without the need for rewiring, up to 6 connections for the secondary side of CTs.
