Title :
Interference of EFT on monitoring system of coal mine electric power safety
Abstract :
The electromagnetic environment of the substations in mine suffers serious contamination. There are a lot of electromagnetic interferences in mine. The Electrical Fast Transient/burst (EFT) is a fast uprising, short-time, low-energy and repetitive pulse high group, which lias significant influence on monitoring system of mine safety. The concept of EFT is introduced in this paper. The hazards of EFT interference on monitoring system of mine safety are analyzed. Meantime, the hazard´ s countermeasures of EFT interference on monitoring system of mine safety are analyzed. For design of monitoring system of mine safety, the countermeasures of EFT interference are very effective.
