6、stract : Dielectric materials are widely on used in various radiating environment . When they are radiated , not only the charge will cumulate inside and on the surface of the material , leading a pulse discharge phenomenon , but also a permanent change on physical and chemical structure of the mate

7、rial is happened. Therefore , before any kind of dielectric is used into spacecraft , the charge character and degradation of the raw material in space radiation environment must be researched. In this paper , a special mesh electrode system that can be used to measure space charge of the material i

Its application in a smeltery s 220kV substation can meet the harmonic suppression requirement well and the effect is obvious for both the high performances and low cost . China has few applications of high2capacity shunt hybrid active power filter till now , hence the given parameter design method and engineering experience are useful for applications and research of other active power filter.
