| Abstract: | Differential relays are widely used in power system，escially in busbar protection.Some main differential relays which are used in busbar protection at present include current differential relay,ratio check differential relay,strong current check differential relay and complex percentage differential relay etc. Their principles and characteristics are analyzed and compared in this paper. |
