METHOD OF DETERMINATION OF REMAINING LIFE OF ELECTRIC WIRING Russian patent published in 2015 - IPC G01R31/02 

FIELD: electricity.

SUBSTANCE: transient resistance of contacts and conductors, total resistance of insulation of the circuit phase - zero, phase - phase, phase - protective conductor without shutdown of power supply, total resistance of insulation of the circuit phase - protective conductor without shutdown of power supply and triggering of the protective shutdown device, total resistance of the line and the circuit, resistance of the grounding devices, the expected short circuit current, differential current of earth leakage, coefficient of absorption and coefficient of polarization. The measured parameters are used for formation of hardware influencing factors in a fuzzy logic system. The distinct hardware influencing factors are normalized for bringing to the same range of their variation. The range of variation of remaining life of electrical wiring in the fuzzy logic system in such a way that at the end of the script conc.m in view of the rounding function round the dependence between the remaining life of electrical wiring, current value of the remaining life of electrical wiring and values of remaining life of the electrical wiring at the worst and best values of hardware influencing factors in view of the maximum service life of electric wiring is established.

EFFECT: improving accuracy of determination of remaining life of electric wiring.
