Overview

The CT volt ampere characteristic tester supports the detection of CT and PT. It meets the requirements of regulations such as GB 20840.3-2013 and GB 20840.2-2014. Without the need for external auxiliary equipment, all testing items can be completed on a single machine. One test can simultaneously complete excitation and transformation ratio polarity tests, and can test transformer bushing CT
