KDZD automatic capacitance and inductance tester is specially developed for the problems existing in the field measurement of capacitor capacitance value in substation. It focuses on solving the following problems:

(1) On-site measurement of capacitors needs to remove the connection line, which is not only a large workload but also easy to damage the capacitor.
(2) The capacitor meter output voltage is low, resulting in low fault detection rate. The instrument has the characteristics of small measurement workload, fast and simple, stable performance, accurate measurement and high fault detection rate.
(3) Measure the inductance of the reactor.
