FIELD: defectoscopy.
SUBSTANCE: invention relates to the field of nondestructive testing and can be used to prevent a fire in the event of a malfunction in the electrical network. Device for non-destructive testing of malfunctions in the electric network contains an input board to which via an electrical network and a transient resistance an electrical installation is connected, to which a total current measuring unit is connected. Power supply unit is connected to the total current measuring unit, to the amplification unit, to the unit for the accumulated signal value comparing with a predetermined value and to the fire hazard signal generating unit. To the total current measuring unit the in the electrical network, a low-pass filter is wired up connected to the power supply and the amplification unit, which is connected to a unit for the accumulated signal value comparing with a preset value to which the fire hazard signal generation unit is connected. To the comparator unit a threshold controller is connected, which is connected to the power unit. Total current measurement unit is connected to the input board.
EFFECT: enabling non-destructive monitoring of a malfunction in the electrical network to prevent a fire.
