Partial discharge inception of interface voids versus mechanical surface pressure

Abstract: Interfaces between insulating solids are generally weak regions particularly if the electrical stress is applied parallel to the interface. This paper presents the results from theoretical and experimental examinations on the partial discharge inception 50 Hz stress of the interface from XLPE samples between two Rogowski profile electrodes. Based upon the measurement of surface roughness, a model was developed to predict the average size of air enclosed surface voids using the elastic contact theory. The effec… Show more

“…Hasheminezhad [11,[52][53][54][55][56] studied the interfacial breakdown strength of solid-solid interfaces between 2007 and 2011 within the scope of his Ph.D. work. During this time, he investigated the BDS and PD inception field strength of XLPE-XLPE interfaces under a homogeneous AC field by varying the contact pressure (p a ) and surface roughness.…”

“…Several studies in the literature considered the electrical behavior of the solid-solid interface [9], [10]. The effect of contact pressure and surface roughness on the breakdown strength of the interfaces has also been evaluated [2], [5]. The higher interfacial pressure and smoother surfaces lead to higher breakdown strength [1]- [5].…”
