In order to reduce the reactive power loss, the power system usually uses a parallel capacitor bank method to improve the power factor. In practical applications, the accident compensation 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 check the capacitor device regularly and find capacitor defects early to avoid the expansion of the fault.
In the field, the capacitors are connected in parallel in groups, so the general capacitance meter needs to be removed after the lead wires are removed, the workload is large, and the wiring errors are easily caused. To this end, the newly developed capacitor and inductance tester of our company measures a single capacitor of a group of parallel capacitors without disconnecting the wire, and can also measure the inductance and current; the wiring is convenient, the operation is simple, and the workload of the maintenance personnel is reduced. The test efficiency of the site is greatly improved, and the safety guarantee for the normal operation of the power grid is provided.
