Reactive power compensation capacitor is an important equipment to satisfy reactive power balance in power system. A large number of reactive power compensation devices are put into the distribution network to balance the active power and reactive power in real time. Reactive power compensation device should meet the requirements of automatic tracking and real-time compensation, so it is inevitable to frequently cast and cut reactive power compensation capacitor banks. The switching and switching operation of the capacitor bank will produce overcurrent and overvoltage impact, causing damage to the capacitor. In order to ensure the reliability of the equipment, it is necessary to detect the capacitor defects early and avoid the expansion of the fault regularly. Capacitance inductance tester is specially used for measuring capacitors and reactors of reactive power compensation system. The instrument adopts advanced measuring principle and four-terminal measuring technology to measure group shunt capacitors and various reactors.
