Yuan Rong · Dianli zidonghua shebei · 2000
The principle of current differential protection based on sampled values is investigated.The relation between this protection and the conventional current differential protections is discussed.The protection has particularity on its inconstant trip boundary.The inconstant area of the trip boundary is quantitatively educed.The appropriate trip speed of the protection is illuminated.
