Abstract With the microcomputer protection device widely using, the anti-jamming performance, the operating characteristics and principle of the grid are carried out fully by the secondary equipment manufacturer of microcomputer protection device, to ensure the reliability of the protection device itself. Standards and regulations to become the reliable operation of the power system operating units important factor, TA secondary circuit has become one of the important reasons for correct action rate impact of microcomputer protection. TA secondary circuit defects will generally be reflected in the protection devices, any alarm protection devices are important prompt, if not promptly eliminate defects that may affect the reliability of the protective equipment, and to expand the scope of the accident.
