METHOD FOR NON-DESTRUCTIVE TESTING OF FAULTS IN THE ELECTRICAL NETWORK Russian patent published in 2021 - IPC G08B17/06 G01R31/00 

FIELD: electrical engineering.

SUBSTANCE: method for non-destructive testing of faults in the electrical network includes the connection of an input board with two electrical installations, the current of each electrical installation is measured, the data obtained on the current value is transmitted to a microcontroller, the change in the thermal EMF is analyzed when each electrical installation is turned on and off, the resulting total voltage of the electrical network is reduced, filtered, isolating the thermal EMF, which is amplified and compared with the set voltage value adopted for the corresponding degree of fire hazard of the electrical network, a warning signal is generated about the occurrence of a fire hazard situation, depending on the magnitude of the set value of the signal received for the corresponding degree of fire hazard.

EFFECT: expansion of the arsenal of technical means.
