TH2882A Series Impulse Winding Tester

Tonghui TH2882A series impulse winding tester, adopting high-speed sampling technique, is a new generation analysis test instrument for insulation performance of coil products.

When testing, TH2882A compares the standard waveform stored in the instrument with current measuring waveform. TH2882A gives the PASS or FAIL comparison result according to Area, Differential Area, Corona Discharge, Differential Phase etc. With strong function, precision test method, flexible operation and various interfaces, TH2882A can provide test solution for most coil winding products.
