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.
