【Introduction】
The ST-1K combines high and low inductance test technology applications, with 1,000 VDC waveform voltage and 200 MHz high-speed sampling rate, which can provide 0.1μH~1mH wide range inductance product testing to meet most power inductor testing needs. It has area and comparison, area difference comparison, corona discharge amount, corona discharge number, inductance value percentage error comparison, corona waveform detection, breakdown voltage analysis function and other judgment methods, which can effectively detect poor coil self-insulation.
The production inspection of winding components includes electrical characteristics and electrical safety withstand voltage testing, and poor coil self-insulation is usually the root cause of interlayer short circuit and pin short circuit in the coil in the use environment. The cause of its formation may be caused by poor initial design, poor molding process, or deterioration of insulation materials. Therefore, the ST-1K is the necessary instrument for the winding components.
