Abstract :
AN IMPROVED network relaying system utilizing a conventional single-phase relaying element and plunger type overcurrent elements excited by symmetrical phase sequence components to represent completely power flow conditions and control protector operation on a 3-phase 4-wire secondary network system is described in this paper. The general features of relay design and operating experience are outlined in the companion paper “A Sequence Relay for Network Protectors.”
