GIMS for Ground Distributed Lightning&Interference For MV and LV Appliatoin

GIMS can be applied to the entire distribution network system, especially suitable for distribution rooms, control rooms, and even single equipment. The device has three main functions: firstly, by continuously monitoring various parameters such as grounding resistance, grounding current, and grounding potential of the grounding network online, it is convenient for users to timely grasp the real-time status and deterioration process of the grounding network; The second is to effectively defend against high-frequency interference in the ground grid, suppress secondary equipment interference caused by ground potential counterattacks, ground overvoltage, etc., and reduce the misoperation and measurement errors of comprehensive automation control systems and precision instruments; Thirdly, it can effectively isolate high-frequency lightning currents, prevent lightning currents from invading the protective grounding network from the lightning protection grounding network, and significantly reduce the damage and impact of ground potential counterattacks and arc faults on equipment caused by lightning hazards.

GIMS consists of a monitoring unit, a measuring unit, a ground interference suppression unit, and a ground potential counterattack suppression unit. Realize real-time online monitoring of the ground grid status, effectively suppress ground grid interference and ground potential counterattack, and achieve intelligent, data-driven, unmanned, and self-healing capabilities of the ground grid.
