A next-generation analytical testing machine that adopts high-speed sampling technology to measure the insulation performance of coil products.
During the examination, the standard waveform stored in this device is compared with the current measurement waveform. It provides PASS or FAIL comparison results based on area, differential area, corona discharge, differential phase, etc. The TH2882A series, equipped with powerful features, accurate testing methods, flexible operation, and various interfaces, can provide testing solutions for most coil winding products. Coil products (such as transformers and motors) may experience insulation failures between coil layers, circles, and leads due to factors such as coil wire materials, magnetic materials, structure, and manufacturing techniques. The impulse winding tester of the TH2882A series adopts high-speed sampling technology and is a new generation of analytical testing equipment for measuring the insulation performance of coil products.
