摘要：

Charge comparison is a new transmission line protection system. It is a form of current differential relaying. Charge comparison largely resolves the traditional problems of current differential relaying of transmission lines: protection is lost if channel fails, large channel capacity required and precise channel delay compensation required. This new technique is suitable for the protection of two - or three-terminal ac transmission lines, of all lengths and voltage levels, with or without series or shunt compensation, with three-pole or single-pole tripping.
