TH2882A-3 Impulse Winding Tester 40 MSPS Sampling 4 Waveform Comparison

Due to the influence of coil wire material, magnetic material, framework and manufacture technics etc., coil products (such as transformers, motors, etc.) may have defects of low insulation between coil layers, circles and leads. 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. The impulse winding tester tests the electrical characteristics of coil winding without damaging the DUT. The prerequisite conditions for quality of a coil can be detected at just a glance. The detection is carried out when the same electric impulse by capacitor discharge is applied to the standard and the DUT. The voltage decay waveform is generated in response to the impulse, related to the Q-factor and inductance of the coil. In this sense, the tester can detect turn & layer short, the differences in the number of turns and the material of the core. If high impulse voltage is applied, the poor insulation will appear as a corona or layer discharge.
