Overview

Reactive power compensation capacitor is an important equipment to satisfy the reactive power balance of the power system. In recent years, the problem of reactive power has received general attention from the electrical industry, and a large number of reactive power compensation devices have been put into operation in the distribution network. Power supply requires real-time balance of active and reactive power in the system. Therefore, the reactive power compensation device should meet the requirements of automatic tracking and real-time compensation, which inevitably requires frequent switching and switching of reactive power compensation capacitor banks. The switching operation of the capacitor bank will produce overcurrent and overvoltage shocks, which will cause damage to the capacitor. In order to ensure the reliability of the equipment, early detection of capacitor defects and avoid the expansion of faults, regular inspections are required. In the field, capacitors are all connected in groups in parallel. The traditional method is to remove the capacitor bus and then measure with an old-fashioned capacitor meter. Since the capacitor bank is composed of dozens to hundreds of small capacitors, it is necessary to disconnect the wires to measure the capacitance. The amount is large, and frequent removal of the wires will cause the screws to slip or not tighten, leaving a safety hazard, and it is also easy to cause secondary damage to the capacitor. Therefore, it is very desirable to have a test instrument that can measure the capacitance of each small capacitor without removing the wires, reduce the burden on maintenance personnel, improve the efficiency of maintenance work, and improve the safety of the distribution network operation.
