Leakage current of metal oxide lightening arrester with PSCAD simulation
Chao Ma · Information technology newsletter · 2013
With the development of the times,metal oxide lightning arrester(hereinafter referred to as the MOA) in the excellent technical performance,reliability and stability gradually replaced other types of lightning arrester,become you to be bestowed favor on newly.And it gradually become the upgrading of the power system protection equipment.MOA has no discharge gap,and one of the core components of zinc oxide resistance for a long time in voltage operation,in which each series resistance MOA leakage current flows continuously,and leakage current and thermal stability and resistance by MOA of aging degree of the decision.So the operation of the monitoring MOA leakage current,judging correctly its influence is very necessary.In order to simulate the dynamic current process,the paper finds out some reliable model.For example: IEEE,Pinceti-G ianettoni and Fernadez-Diaz passed the PSCAD review.And through the PSCAD simulation for it provides the more shortcut,intuitive data.
