Low Voltage CT Turn Transformation Ratio Tester Leakage Current Test Transformer

Note: Battery not Included During The Shipping !!!

Introduction:

• Low-voltage CT ratio tester can be widely used in 380/220-volt power system, which can easily and quickly realize online on-site testing of current transformers in metering devices and determination of current and leakage current values in 380/220-volt power system, realizing accurate testing of current transformer ratio, angle difference, phase difference and polarity in actual operation without power outage. 
• The tester is composed of mainframe, primary flexible current clamp and secondary current clamp. The diameter of the flexible current clamp is 8mm, which is especially suitable for narrow space and dense lineup of testing places.
