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.
