Partial Discharge Detection System with Computer
RSJFD system detection method is pulse current method which is currently most widely used in the world, the basic principle is following: when the test object generates one time partial discharge, there is the transient voltage change △U on both terminals of the test object ,then go to the detection impedance Zm via a coupling capacitance Ck, then there will be one pulse current I in the circuit. Sample the pulse voltage generated when this pulse current I passes the detection impedance Zm , amplified and displayed, finally, it can determine the actual loaded discharge, etc. of the partial discharge. The pulse current method mainly uses the lower frequency part of the partial discharge signal frequency spectrum, which can avoid wireless interference.
RSJFD system is a testing system in the form of pulse peak indication, it possesses functions such as computer program-controlled filtering, amplification, sampling, storage and display. It can test the actual loaded discharge q, discharge repetition rate n, average discharge current I, and quadratic rate D, it also can make different atlases: q-n, q-φ, q-φ-t, etc.
