The CT and PT Tester is a revolutionary testing system for various CTs and PTs according to standards IEC61869-2 (IEC60044-1, 60044-6), IEC61869-3 (IEC60044-2), and IEEE/ANSI C57.13. The Analyzer can automatically complete tests within seconds with one click of the patented multifunctional rotary mouse. It allows testing of knee-point voltages up to 40kV on-site or in production facilities.
Weight: 9kg (19.84 lbs) - highly portable for field testing.
