Product Description

High-low Voltage Current Transformer Ratio Tester is a new electricity inspection device for high voltage metering users. It is able to test metering device current transformer’s ratio and polarity with voltage of *5KV or less under the condition of not shut down the electricity and not changing the wirings. So that it is able to effectively avoid high voltage metering users changing the high-low voltage current transformer or changing the current transformer nameplate as well as changing the polarity of second wire with the purpose of using electricity illegally.

 Main features

1.   Able to test ratio, polarity and phase of high-low voltage current transformer with voltage of *5KV or less;

2.   Able to test the current frequency of high-low voltage wire with voltage of *5KV or less;

3.   Large capacity lithium battery can work for *0 hours continuously;

4.   Long U type clamp mouth makes the width of the tested thing ups to *5mm;

5.   Extendable and shrinkable insulated bar, easy to take.

6.   Closed clamp-on design makes the accuracy higher than opening design, which greatly improves the accuracy.
