Mobile tank grounding device MGV

MGV is a mobile earthing control system designed for installation directly on road tankers, which are used to transport flammable and explosive substances, i.e.: liquid fuels, including liquefied gases, solvents, alcohols, fermentable materials with methane release. Its task is to reduce the risk of explosion that may occur as a result the jump of an electrostatic spark. This solution therefore increases the security of the process and allows to fulfil the obligations arising from the relevant regulations of the Minister of Economy. System components electronic earthing controller – designed for use in explosion hazard zones, spiral cable (with hytrel casing) or reel with cable, robust stainless steel clamp with sharp teeth made of tungsten carbide. The MGV system verifies the earthing in three steps before issuing permission to start loading/unloading the road tanker: checks that the fixed connection between the MGV system and the tank structure is correct (this solution ensures that the system is connected to a tank component that effectively receives electrostatic charges from the whole structure and indicates an error when the connection is broken), checks that the clamp is connected to a earth point that allows the charges to be effectively discharged to the ground (it happens that there is no access to the cooper near the place where the reloading is carried out. In such cases it is possible to connect the clamp to another metal component which is buried in the ground – e.g. a lightning conductor or a steel pole. The system will check whether their resistance is less than 10 Ω, and thus whether they are capable of effectively discharging charges to the ground),
