Some thought about development target of testing for relay protection equipment

With the fast development of computer technology,communication technology and information technology,the relay protection equipments have involved the protection,monitoring,control and communication functions as an integrative body,meanwhile,the new requirements of time synchronization and system security also come to be the extra contents of relay protection testing.To evaluate the quality of relay protection equipments more reasonably and precisely,and ensure the reliability of their application in power system,the supplement and revision of the testing content and the improvement of testing methods are needed on the basis of the existing relay protection type test.This paper discusses the target of relay protection testing according to the new characteristic of relay protection technology,it is hoped that readers working on the relay protection could gain some inspiration from this paper.
