For analysing fault of a power system which become increasingly complex, the basic function of fault recorder for a power system are described here. Emphasis is placed upon microcomputerization of equipment as primary feature and its development,powerful fault analysis, real-time angle measurement and power-angle monitoring,precise fault ranging,network-formed of system, etc; and also upon the feasible scheme of implementation. Software development is based on Windows and hardware,on modularization. Thus it is characterized by friendly system interface, very good real-time operation, easy to extend, high reliability, and simple and convenient maintenance. By the establishment of global positioning system and the widely application of computer and microwave fiber-optical communication to power system, the fault recorder will develop into a multifunctional fault recording and monitoring system.
