Abstract
With the development of high speed railways, there are higher requirements to insure the reliability of the traction power supply system. In this paper, a novel insulation on-line monitoring and fault diagnosis system based on the embedded Linux operation system is introduced. The system can continuously monitor the insulation state of the power instruments, such as traction transformers, arresters, circuit breakers, and insulators. Different monitoring techniques were applied in the system. The embedded Linux operation system with TCP/IP protocol makes the field monitoring devices possess the powerful data processing and networking functions. The monitoring system builds a good basis for traction substation insulation on-line monitoring and diagnosis.
