In an electrical installation, an earthing system or grounding system connects specific parts of that installation with the Earth's conductive surface for safety and functional purposes. The point of reference is the Earth's conductive surface. The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. . Regulations for earthing systems vary ...
Sofamel Earthing Single Earthing Leads are single phase earthing equipment. Sofamel Earthing Single Earthing Leads have the MPU/B or MPU/H clamp which allows the earthing connection of the lines for repair operations.
Home-Made Grounding Device ... Earthing shoes can be purchased from various companies. But be advised that they only work on dirt or grass. Concrete is a poor conductor, especially if sealed or painted. Concrete is usually poured over a plastic moisture barrier.
Unitest can supply portable earth systems to your requirements for sub station or overhead with copper or alum cables and ratings to 45kA with standard ratings 10/16/25kA per 0.5sec. Distance between phases & downlead length to your needs.
The Sofamel PATL-MPLB Earthing and short-circuit kit is designed for work on medium voltage overhead lines. The equipment offers protection against an accidental commissioning or voltage return during maintenance and repair operations.
In electricity supply systems, an earthing (grounding) system defines the electrical potential of the conductors relative to that of the Earth's conductive surface. The choice of earthing system has implications for the safety and electromagnetic compatibility of the power supply.
Portable Earthing equipment for high voltage electricity networks provides safe and reliable earth clamping where connections are to be made to dirty or heavily oxidised copper or aluminium busbars or stubs : this includes portable earthing systems for 33kV, 66kV, 132kV, 275kV and 400kV.

Portable Earthing Equipment are safety equipment designed for discharging & grounding of dead equipment. The system is designed for high fault levels so that even if during shut downs, when technicians are on the job, by mistake if the supply is switched ON, the Portable Earthing Equipment saves human life as well as equipment under maintenance.
earth's surface; a conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of the earth. Ground Connection—An electrical connection of the welding machine frame to the earth for safety. Grounded—Connected to earth or to
Equipment earthing is a connection done through a metal link between the body of any electrical appliance, or neutral point, as the case may be, to the deeper ground soil. The metal link is normally of MS flat, CI flat, GI wire which should be penetrated to the ground earth grid.
Portable Earthing of High Voltage Conductors Revision No: 2 Page 8 of 31 Where the fault rating of the location exceeds that of the equipment, multiple sets may be used to increase the rating of the earthing system:

Maintenance Free Chemical Earthing A well-designed Earthing system is essential for any electrical installation to avoid dangers associated with fault currents. Good Earthing protects both equipment and people against dangerous step & touch voltage.
This equipment is for providing temporary earth bonds between overhead catenary or contact conductors and earthed rail sections or recognised earthing points. The equipment has been specially enhanced in order to address the potentially fatal procedure of removing the equipment in the incorrect order from service.
Figure 1 – Portable generator set neutral earthing system. If the generator set supplies class II devices, the exposed conductive parts are not linked but the provision of one or more RCDs remains mandatory for supplementary protection against direct contact, in particular on the flexible connecting cable.
8 Photovoltaic System Grounding Earth Connection The metallic device used to make contact with the earth is the grounding electrode. The conductor that connects the central grounding point (where the equipment grounding system is connected to the grounded circuit conductor on grounded systems) and a
frame of a portable generator need not be grounded (connected to earth) and that the frame may serve as the ground (in place of the earth): • The generator supplies only equipment mounted on the generator and/or cord-
The TN-S system (5 wires) is obligatory for circuits with cross-sectional areas less than 10 mm 2 for portable equipment. The protective conductor and the neutral conductor are separate. On underground cable systems where lead-sheathed cables exist, the protective conductor is generally the lead sheath.
Maintain and operate portable generators in accordance with the manufacturer's use and safety instructions. Never attach a portable generator directly to the electrical system of a structure (home, office or trailer) unless the generator has a properly installed open-transition transfer switch.
