STB8882A Series Impulse Winding Tester

Overview Specifications Ordering Resources

STB8882A series impulse winding tester, adopting highspeed sampling technique, is a new generation analysis test instrument for insulation performance of coil products.

When testing, STB8882A compares the standard waveform stored in the instrument with current measuring waveform. STB8882A 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, STB8882A can provide test solution for most coil winding products.

** Standard Lead Time: within 4 weeks **
