Product Introduction With the development of China's electric power industry the capacitor compensation device has been unprecedentedly developed but with it the capacitor accident rate has risen sharply and there have been serious group injury accidents. In order to prevent the occurrence of parallel capacitor accidents and ensure the safe and reliable operation of the power grid State Grid Corporation has formulated the "Measures for Preventing High Voltage Shunt Capacitor Accidents". It is clearly stated that "the measurement of the capacitance of a single capacitor of a capacitor bank should be carried out on a regular basis. It is recommended to use a measurement method that does not remove the connecting wire to avoid the failure of the casing to leak due to the force of the casing caused by the disassembly and assembly of the connecting wire".
