Partial Discharge Test System RSJFD-251 120 dB Gain Dynamic Range

Detection method based on RSJFD system is a current pulse method is widely used in the world, its basic principle diagram: a partial discharge test, test voltage change △ U Cx generated at both ends of the instantaneous, through the coupling capacitor Ck coupled to the detecting impedance Zm, circuit generates pulse current of I, the pulse voltage and current I by detecting the impedance of Zm sampling, amplifying and display processing, parameters can be measured partial discharge load discharge quantity. Pulse current method mainly uses the low frequency part of the partial discharge signals in the spectrum, can avoid the wireless interference.

System for the pulse peak indicating form test system, with computer program control filter, amplifier, sampling, storage and display function. Can test the real load discharge quantity and discharge repetition rate of N, Q, average discharge current of I,, square rate of D, can be used for various patterns: q-n, q-φ, q- φ -t
