| Abstract: | To solve hidden troubles existed in the single phase grounding of small current grounding systems,a compensation technology of tracing the arc suppression coil automatically is introduced including its principle,properties and features. Adopting a device of the technology will be good for acting best compensation automatically,decreasing remainder currents in fault points,restraining effectively damages of the overvoltage arc lighting,preventing some faults such as the phase to phase short circuit caused by the single phase grounding,the explosion of cables,etc. |
