The selection of insulant for any power system required its characterization in addition to its testing; the effi cient and longevalspan of the insulant is vital even under extreme conditions. This paper characterizes the Polymer-based solid insulant viaPartial Discharge (PD) measurement using artifi cially created stress condition with the CIGRE-II based electrode systemover the polymer-based insulation sheets having simulated cavities of diff erent confi guration. Assessment of insulation usingPD features provides pre-breakdown situation and provide capability to comprehend the mechanism of insulant’s debilitation.
The digital PD system is modern diagnosis toolkit (MPD 540) based on IEC 60270 with the competency of fi lteringinternal PD signals from external Interference and Discharges implement for collecting data. The evaluated PD voltages forartifi cially created voids vary in number and size in each polymer based dielectric sample to realize PD model. The controlledsized cavities signifi cantly infl uenced the PD inception and extinction voltage with variable size and a diff erent number ofcavities extant in dielectric samples. The possibility of PD process continuum or extinction after each discharge event ininsulation predicted using Weibull probability distribution for each distinct size cavity. The cylindrical cavity’s diameteralong the direction of the electric fi eld signifi cantly deteriorates the reliable operation of insulation as compared to its depth.
