Summary of instrument
Reactive power compensation capacitor is an important equipment to satisfy reactive power balance in power system. In recent years, the problem of reactive power has been paid more and more attention by the electric industry. Power supply requires real-time balance between active power and reactive power. Therefore, 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. And capacitor are group in parallel on the spot, the traditional method is to remove the bus-bar capacitance, and then use the old capacitance meter measuring, because the capacitor group is composed of tens to hundreds of small capacitors, take out stitches to measure the capacitance of a lot of work, take out stitches and often makes the sliding teeth or not to tighten the screw and leave a safe hidden trouble, also can cause secondary damage capacitance. Therefore, it is very expected that a test instrument can measure the capacitance of each small capacitor without removing wires, reduce the burden of maintenance personnel, improve the efficiency of maintenance work, and improve the safety of distribution network operation.
Three-phase inductance capacitance tester can not remove the state, the measurement of the single phase or various combinations of group parallel capacitor connection type three-phase capacitor, at the same time also can measure all kinds of reactor inductance, the instrument can also measure the condition of power frequency current, the instrument connection is convenient, simple operation, reduce the maintenance staff work, It greatly improves the test efficiency and provides security for the normal operation of power grid.
