| Abstract: | Type WXH-25 microprocessor - based complete line protection fol single - terminal POweT source system or double-terminal power source system is introduced. The protection uses fault component to identify internal fault in a single terminal power source system,and thus solves the reliable trip problem in mace of using permissible signal. its main protection can response different faults and has higher security and reliability. The features of backup protection is also introduced. Addition to conventional recloserlug method,the recloser of the protection has an optional mode of blocking reclosure against single--phase permanent fault. |
