Automatic System of Monitoring and Diagnostics of Sparking in Contact

Abstract

Abstract. Most common occurrence of a short circuit is a consequence of a combined impact of various ignition sources -electrical sparking or monotonic alteration of resistance in contact joints -on the low-voltage network. An automatic system of monitoring and diagnostics of electrical wiring in case of an electrical sparking or monotonic alteration of the electrical contact resistance was developed. We suggest two ways of applying the elaborated system: the stationary and the mobile one. The system has two ways of applying: the stationary and the mobile one. It estimates permanently the level of fire safety of the power supply system and promptly form a signal for the abnormal electrical wiring power cut and a signal of its level of fire risk. In addition, the introduced system can serve as a subsystem for providing a controlled level of fire safety in the "Smart house" or "Smart Grid" systems.
