Adopted technology of ARM chip controlling output and toroidal transformer with high-capacity and equipped with LCD display meter, the HZDL-N2 Primary Current Injection Tester could simultaneously display primary current, secondary current and turn ratio. 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.
