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