METHOD FOR TESTING AN OBJECT CONTAINING CRITICAL ELEMENTS FOR CURRENT PROTECTION AND SIMULATORS OF CRITICAL ELEMENTS Russian patent published in 2023 - IPC G01D21/00 F42B35/00 G01R31/00 

FIELD: current protection; electromagnetic fields.

SUBSTANCE: invention relates to testing an object containing critical elements for protection from the action of currents emerging from electromagnetic impact on the object (electromagnetic fields and lightning currents, static electricity, radio transmitters, high-voltage power lines, etc.). The method of testing an object containing critical elements for immunity from currents emerging from electromagnetic impact on the object consists in electromagnetic impact with specified parameters on an object in which a fire-explosive substance simulator and a bridge-type electric igniter simulator are installed. Each of the simulators includes a sensor of increased sensitivity to the action of the current, characterized by a sensitivity factor K, determined by the formula K=W_CE/W_A≥1, where W_CE is the level of insensitivity of the critical element to the action of a typical current pulse, at which it is guaranteed not to operate; W_A - the level of sensitivity of the sensor to the action of a typical current pulse, at which it is guaranteed to operate. The fact that the object is protected from the action of the current is established if after electromagnetic influence none of the sensors will work. The simulator of a fire-explosive substance and the bridge-type electric igniter simulator contain sensors in the form of a resistor with leads and electrodes placed in an inert medium within the overall dimensions and electrical characteristics of the corresponding critical element.

EFFECT: ensuring the adequacy and improving the safety of tests.
