Research on Instantaneous Grounding Positioning Technology for DC Systems Based on Wireless Communication
The latest insulation monitoring devices for DC systems on the market are capable of detecting millisecond level instantaneous grounding faults in DC systems and selecting feeder branches during instantaneous grounding.However,due to the sporadic and non persistent nature of transient grounding faults in DC systems,portable grounding locators cannot be used to locate the fault point.This article designs a DC system instantaneous grounding positioning system based on wireless communication to locate instantaneous grounding fault points.
