Coil products (such as transformers, motors, etc.) due to the winding materials, magnetic materials, skeleton, processing technology and other factors will produce a coil between the layers, turns and pins, such as insulation performance degradation.TH2882A series of impulse coil testers is a new generation of coil products using high-speed sampling technology to develop insulation test instruments, can provide test solutions for most coil products. The TH2882A stores the sampled waveforms of standard coils in the instrument, compares the measured waveforms with the standard waveforms during testing, and determines the advantages and disadvantages of the coils under test according to the set criteria (area, area difference, phase difference, corona, etc.).The TH2882AS is mainly used for testing all kinds of three-phase, three-wire or three-phase, four-wire motors with three sets of coils, and the test waveforms can be compared with the standard waveforms inside the instrument, and the test waveforms can be compared with the standard waveforms inside the instrument, and the test waveforms can also be compared with the standard waveforms without standard waveforms. The test waveforms can be compared with the internal standard waveforms of the instrument, and the consistency can also be compared among different coils without the need of standard waveforms.
