FIELD: electricity.
SUBSTANCE: group of inventions relates to systems for detecting lightning strike. Invention discloses a method and a device for detecting a lightning strike with self-contained power supply. Current spike is delivered through a current return network that energizes a resonant circuit to produce an alternating electrical output. Said output is rectified by a rectifier into direct output that is then transferred to an integrator circuit. Integrator circuit slowly builds to and dissipates from a voltage threshold corresponding to an output transistor. When transistor is triggered by voltage threshold this trigger is communicated to a fault monitoring software that recognizes current spike.
EFFECT: technical result consists in improvement of accuracy and reliability of detecting lightning strike.
