The acronym MEP became an integral word of a building project in Middle East Gulf region during year 2000. In the inception stage of MEP, there were involvement of only two engineering branches, Mechanical and Electrical, now it included electronics, instrumentation and communication. In some occasions, Mechatronics also partake in the project for smooth completion of the whole MEP works. Companies that carry out MEP works also known as Electro-Mechanical company which has multi-faceted technicians and engineers for effective design, coordination and execution of the works.
Electrical Earthing or Grounding System for buildings to be carried out all in accordance with the international standards in conjunction with the local authority requirements and recommendations. Earthing standards and methods are highly depending on the nature of the utilities and equipment installed / used at the premises. Simple earthing system we provide to the domestic connections while complex systems are being used in the power stations and industries.
Comply with the General Conditions, Supplementary Conditions and the requirements in various Sections of the Electrical Specification. In addition read and conform to all Electrical Sections of these specifications. The installation shall comprise air networks connected to roof and down conductors and finally terminated in earth electrodes, via structural re-bars and suitable test points in accordance with the details included on the attached drawings or in the Specification Section.
Clean earth grounding or low noise earth shall be provided as required, to ensure that the level of induced or conducted interference from external sources, including the facility power grounding system, does not produce incidence of malfunction of the equipment, which is unacceptable for the operating system. The electronics systems must be protected by providing a network path having low impedance for interconnecting its equipment.
Proper routing, zoning and shielding of the cables / earth wires are important and must serve the purpose of preventing sources of electrical disturbances from the operation of electrical equipment.
Component parts of earthing system are to include the following:
- Earth electrode (rods, tapes etc.)
- Main earthing terminals or bars
- Earthing conductors
- Protective conductors
- Equipotential bonding conductors
- Electrically independent earth electrodes for special systems (clean earth)
- Accessories and termination fittings, bonding, welding kits and other materials
