EMI and Lightning Protection for Control

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.

TOVS is a multifunctional electrical safety active defense device that combines lightning overvoltage suppression, ground potential counterattack overvoltage suppression, operation overvoltage suppression, resonance overvoltage suppression, voltage temporary rise regulation, and load interference suppression.
TOVS power interference suppression device is installed at the load to be protected and can be fixed on the wall or installed inside the distribution cabinet. Ready to install and use, without affecting the normal operation of monitoring systems such as lightning and electrical fires.
TOVS power interference suppression device is easy to debug. After the device is connected, use a multimeter to measure whether the incoming power supply is normal. After power on, the device will automatically enter the operating state, and the current indicator of the device will display the output current. When overvoltage occurs, the device actively suppresses and protects without any operation.

GDIS is suitable for key sensitive control equipment (such as DCS and PLC) in continuous production processes, effectively defending against high-frequency interference from the ground grid, suppressing secondary equipment interference caused by ground potential counterattacks, ground overvoltage, etc., and reducing misoperation and measurement errors of comprehensive automation control systems and precision instruments.

The suppression effect of GDIS is minimally affected by the impedance of the grounding grid and has little relationship with the grounding connection resistance. It mainly achieves the ultimate goal of suppressing interference through the defense and energy absorption of the ground grid interference suppressor GDIS itself.

GDIS has higher reliability and shorter action time, which can effectively isolate high-frequency lightning currents, reduce the risk of control system interference, prevent unplanned shutdowns caused by local power outages, and prevent serious disasters such as fires and explosions caused by secondary accidents.
