Algorithms for an Automatic System of Electrical Wiring Monitoring and Diagnos tics
Abstract
Purpose: Studying the sources of electrical wiring insulation ignition in emergency as a scientific basis for improving the fire safety of objects associated with human activity. Results: Most often, short circuit is caused by a combined impact of various ignition sources upon a low-voltage electrical network. Experiments show that when internal electrical wiring is laid out badly, it will suffer from electrical sparking or from monotonous change of the transition resistance. A power contact connection can overheat, exceeding the upper limit of the operational temperature of the isolation and causing its ignition. Average experimental curves were analysed for heating and cooling of power contact connections with given load power values. This helped to build adequate logics for an automated system of monitoring/diagnostics of electrical wiring with sparks or monotonous change of the contact transition resistance. Such a system will allow you to evaluate the quality of wiring and the wear of wires, cables and power contact connections before the wiring is put into operation, providing an acceptable level of its fire safety. Practical relevance: The developed automated system of electrical wiring monitoring/diagnostics will allow you to continuously assess the fire safety of a power supply system, promptly generating an emergency signal to disable the wiring and a fire hazard level signal. The proposed system can also act as a subsystem to ensure the necessary level of fire safety in Smart house or Smart Grid systems.Published
