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".

Automatic capacitance and inductance tester is designed for the problems in the measurement of high voltage shunt capacitor banks in substation sites and refers to GB3983.2-1989 "High Voltage Shunt Capacitors" DL/T840-2003 "Technical Conditions for Use of High Voltage Shunt Capacitors" and JB5346 -1998 "Series reactor" and other national standards and specially developed mainly to measure the high voltage shunt capacitor bank and reactor of reactive power compensation device.

Automatic capacitance and inductance tester adopts a new generation of high-speed hybrid microprocessor which is highly integrated synchronously collects the voltage signal and current signal of the test object and automatically calculates the capacitance value inductance value and reactive power value. On-site measurement of capacitors eliminates the need to remove the connecting lines simplifying the test process effectively improving work efficiency and avoiding damage to power equipment. After the test the capacity of each phase capacitor and other parameters are automatically calculated and it is easy to discriminate the quality change of the capacitor and the connection conductor failure between devices. At the same time the automatic capacitance and inductance tester also features data storage and USB communication eliminating the need to copy data on-site and ensuring complete measurement data.
