ETCR9300 Low Voltage Current Transformation Ratio Tester
ETCR9300 Low Voltage Current Transformation Ratio Tester
. Introduction
ETCR9300 Low Voltage Current Transformation Ratio Tester can widely applied in 380V/220V electric power system, for conveniently and fast online measurement of current transformer in measurement devices, and measurement of current and leakage current in 380V/220V electric power system. Without power cut, it can also accurately measure the current transformation ratio, ratio difference, angle difference, phase, polar. Provide operators with a safe, accurate and convenient tester. Its application will bring remarkable economic and social benefits in power supply management for electric power enterprise.
