An on-line monitoring and multi-layer fault diagnosis system of electrical equipment based on geographic information system

Automated mapping/facilities management/geographic information system (AM/FM/GIS), which provides a powerful way to process graphic and non-graphic information, can construct a spatial database system with topological structure and analysis function by combining diversified information in power system with geographic position-related graphic information. Based on the AM/FM/GIS and on-line monitoring system, an integrated system is put forward which can implement state monitoring, multi-layer fault diagnosis and assess the faults. By using this integrated system, latent fault and defect can be eliminated, loss due to power cut is reduced and the reliability of running power system is improved. Application indicates it is economical, pragmatic and has excellent performance.
