Brief explanation

Coil products (such as transformers, motors, etc.) due to winding materials, magnetic materials, skeleton, processing and other factors, the coil layer, turn to turn and pin insulation performance will be reduced. TH2882A-3 pulse coil tester is a new generation of coil products insulation performance testing instrument developed by high-speed sampling technology, which can provide test solutions for most coil products. The sampling waveform of the standard coil is stored in the instrument, and the measured waveform is compared with the standard waveform in the test. According to the set criteria (area, area difference, phase difference, corona, etc.), the coil is judged to be good or bad. The impulse coil tester needs to test its electrical performance as far as possible without damaging the measured parts. The first condition is to apply the lower energy to the measured parts in a short instant to judge the quality of the coil. When measuring the standard coil when measuring the same pulse through the discharge of the capacitor is applied to the measured coil due to stray capacitance and inductance value of Q, there will be a response to a voltage corresponding to the discharge pulse waveform attenuation, the attenuation of some characteristics of the waveform of the differences between the coils and layer detection between the short circuit and the number of laps and magnetic materials, if applying a high voltage pulse, according to the corona or interlayer discharge to judge the poor insulation.
