AN9691H/9692H (F) Impulse Winding Voltage Tester is a digital tester. It saves surging wave form collected from standard coils and compares the wave form of standard coils with the coils being tested. This tester can judge parameters of corona value, area, area difference and phase difference, etc., which is able to efficiently and precisely test short-circuit between layers, short-circuit between phases, tiny short-circuit, defective insulation, core iron loss and so on.
