Complete Variable Frequency Series Resonance Withstand Voltage Test Set Delivered | Demiks Power Supports Suzhou Jiadian Permanent Magnet Motor HV Motor Electrical Performance Test
Shanghai Demiks Power Technology Co., Ltd, a professional manufacturer of high voltage power test equipment, has recently supplied a complete set of variable frequency series resonance withstand voltage test system to Suzhou Jiadian Feiqiu Motor Co., Ltd. The test equipment is deployed for electrical performance inspection and stator winding AC hipot testing of large power permanent magnet high-voltage motors to guarantee insulation reliability before factory delivery.
For large & medium high voltage motor manufacturing, insulation performance of stator winding determines the long-term safe operation of motors. Every HV motor must undergo strict AC withstand voltage test before leaving factory to discover insulation defects, winding damage and inter-turn hidden faults. Conventional power frequency hipot testers feature heavy weight and limited power capacity, which cannot satisfy the testing requirement of large-capacity high voltage motors. Variable frequency series resonant test set has become the preferred AC hipot solution for large motor factories, with lightweight structure, standard output waveform and large test capacity.
Demiks on-site technical engineers carried out equipment installation, wiring commissioning and test operation training inside Suzhou Jiadian Feiqiu Motor workshop. The whole series resonance system consists of variable frequency power supply unit, high voltage reactors, capacitive voltage divider and compensation capacitors, compatible with AC withstand voltage test for various voltage grade permanent magnet motors. During testing, the system generates stable sinusoidal high voltage, collects real-time data including test voltage, current and resonant frequency. The touch screen displays test curve clearly with automatic protection function. It will cut off high voltage instantly once breakdown or flash-over occurs to protect operators and tested motors.
Suzhou Jiadian Feiqiu Motor specializes in R&D and manufacturing of high-power permanent magnet motors for heavy-duty industries including mining, metallurgy, chemical and energy sectors, with strict requirements for motor insulation inspection. With Demiks variable frequency series resonance test equipment, the factory can independently complete high voltage motor factory insulation hi-pot test in workshop, shorten quality inspection cycle, strictly control product quality and accelerate delivery schedule.
