An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipment's conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.
For building electrical grounding systems or earthing systems, there is a low resistance conductor bonding the metalwork and this is connected to a groundbed. The electrodes for electrical grounding are often called ground rods and are often made from steel with a copper clad surface – typically 1 to 2 m long and 20 millimetres (0.79 in) in ...

Paradise Cables is the leading [ peacock prose ] manufacturer of all types of wires, cables and conductors in Bangladesh.
This is called "system grounding" and most electrical systems are required to be grounded. The U.S. NEC and the UK's BS 7671 list systems that are required to be grounded. According to the NEC, the purpose of connecting an electrical system to the physical ground (earth) is to limit the voltage imposed by lightning events and contact with ...
The primary reason for the use of isolated grounds (IG) is to provide a noise-free ground return, separate from the equipment grounding (EG) return. The EG circuit includes all of the metal conduit, outlet boxes, and metal enclosures that contain the wiring and must be grounded to provide a safe return path in case of fault currents.
Bangladesh completed a second-test victory against Pakistan on the last afternoon Tuesday and achieved an historic sweep of the series. Needing 143 more runs on the final day with 10 wickets in ...
On 27 October 1963, the company was turned into a public limited company. After the Independence of Bangladesh, the company was nationalised by the government of Bangladesh in 1972 through the Bangladesh Industrial Enterprises (Nationalization) order. It is under the Bangladesh Chemical Industries Corporation of the Ministry of Industries. The ...
