Multi-Ratio CT Analyzer

Model: CTP-120PA

The Multi-Ratio CT Analyzer CTP-120PA is all-in-one testing system for protection and metering CTs according to IEEE and IEC standards.

It allows all types of single and multi-ratio current transformers to be tested on-site in power system grids. Manufacturer of CTs, transformers or GIS use the CT Analyzer in their production facilities and test or development labs.

The Multi-Ratio CT Analyzer CTP-120PA also is capable of testing PTs(Potential Transformers, Voltage Transformers).
