Product introduction

Differ from the traditional structure, specially for measuring high and low voltage secondary circuit of a current, variable ratio, relative to other, polarity, leakage current and well-designed. Using the latest CT technology and mask figures integration technology. By a dedicated high voltage detector, low current clamp, the host, high voltage insulation rod, monitoring software and other components, and its wireless transmission of test data can penetrate obstacles to multi-storey buildings, linear transmission distance up to 30 meters. If you do not use insulated rod, but also can be used as high-precision voltage clamp meter, leakage current meter can accurately measure 0.00mA ~ 1000A current or leakage current.

Also called name

CT ratio polarity line detector, high voltage transformer ratio tester, high voltage CT ratio tester, high voltage CT ratio tester, high voltage transformer ratio tester, live measurement of high voltage CT ratio tester, high CT ratio tester

The Characteristics of the products

1. we are the first company who take voltage measuring method in use, small in volume, light in weight, portable, meet the needs for field tests.
