The reactive power compensation device may be disturbed during operation and needs to be tested after a period of use. Especially for self-healing parallel capacitors, which are severely affected by external factors, regular testing is necessary to ensure their stable operation. Today, Baijian will briefly introduce two methods for detecting self-healing parallel capacitors. External observation method 1. If observed from the outside of the parallel capacitor during operation, expansion will occur when the internal insulation medium or electrode is damaged to the shell. Therefore, we need to stop working in a timely manner and replace the capacitor with a new one. If any phenomena such as fuel injection or leakage of internal insulation medium are found in the capacitor, immediately stop the operation of the capacitor and replace it with a new one. 3. The capacitor will not produce any noise during operation. If there is any noise, it can only indicate that the internal fault of the capacitor has occurred. It should be stopped and replaced. Self healing parallel capacitors. jpg insulation megger test. The insulation megger test method is to use an instrument to test parallel capacitors. First, discharge all the electricity in the capacitor, disconnect all connections, and select a megohmmeter. The voltage should be the same as the working voltage of the parallel capacitor. When conducting the test, wear insulated gloves at a speed of 120r/min, and then use a testing pen to approach the parallel capacitor's tested conductor for measurement. After passing through the megger generator for about 1 minute, measure. 1. The megohmmeter starts from scratch and continues to increase, and contains a crisp spark sound indicating good quality and reliable operation. 2. The megohmmeter reading but no spark indicates that the wire connecting the electrode plate and terminal has been disconnected and needs to be replaced. 3. If the megohmmeter remains at zero, it indicates that the capacitor has been damaged and cannot be used.
