An automatic analysis of the reflectograms collected during the partial discharge measurement – using a method referred to as time domain reflectometry (TDR) – allows the location of insulation irregularities.OverviewIn , partial discharge (PD) is a localized (DB) (which does not completely. .
PD usually begins within voids, cracks, or inclusions within a solid , at -dielectric interfaces within solid or liquid dielectrics, or in bubbles within liquid . Since PDs are limited to only a portion of t. .
With the partial discharge measurement, the dielectric condition of high voltage equipment can be evaluated, and in the insulation can be detected and located. Partial discharge measurement can localize the d. .
Once begun, PD causes progressive deterioration of insulating materials, ultimately leading to . The effects of PD within cables and equipment can be very serious, ultimately leadin. .
Utilizing UHF couplers and sensors, partial discharge signals are detected and carried to a master control unit where a filtering process is applied to reject interference. The amplitude and frequency of the UHF partial discharge. [pdf]
