FIELD: electricity.
SUBSTANCE: safety system for use with a plurality of circuit protection devices connected to the distributing gear comprises the first sensor for detecting a body locating within the first zone associated with the threshold distance from the distributing gear, the second sensor for detecting a body within the second zone associated with the second threshold distance from the distributing gear; and a controller connected to the first and second sensors. The controller is configured to selectively activate a plurality of circuit protection devices. The controller is configured to selectively activate a plurality of circuit protection devices and activate the first circuit protection device in response to detecting, by the noted first sensor, body within the first zone, and activate the second circuit protection device in response to detecting, by the noted second sensor, within the second zone.
EFFECT: increased reliability of protection from arc discharges.
