Description
technical field [0001] The invention relates to the technical field of parallel capacitance and inductance testing, in particular to a capacitance device. Background technique [0002] In order to reduce the reactive power loss in the power system, the method of connecting capacitor banks in parallel is usually used to improve the power factor. In practical application, the accident rate of the capacitor compensation device is relatively high, which is determined by the characteristics of the working state of the capacitor device. Therefore, it is very important to regularly inspect the capacitor device, find capacitor defects early, and avoid fault expansion. [0003] In the field, capacitors are all connected in groups and in parallel, so it is necessary to remove the lead wires before measuring with a general capacitance meter, the workload is heavy, and it is easy to cause wiring errors; at the same time, this kind of detection side capacitance device requires a 220V po...
