Huazheng Electric HZ-109S 1000A Primary Injection Test Set

I. Overview

Adopted technology of ARM chip controlling output and toroidal transformer with high-capacity and equipped with LCD display meter, the HZ-109S Primary Current Injection Tester could simultaneously display primary current, secondary current, turn ratio and the actuation time of stopwatch connection position (electric potential). The product possesses the characteristics of nice appearance, large output capacity, small size, light weight and so on with external aluminum alloy case and PC panel. It is mainly suited for CT turn ratio and contact resistance tests of power system and other occasions needed high current test.

Output Time Ratio

Output Time Ratio of High Current Tester
Rated Current	Time(s)
110%	10S
100%	60S
90%	90S
80%	120S
70%	240S
