Earthing

The earthing material that is electrically conductive and a fault current will flow to 'earth' through the live conductor, provided. This is to prevent a potentially live conductor from rising above the safe level. All exposed metal parts of an electrical installation or electrical appliance must be earthed.

Types of Earthing
Supply & Installation of all type of earthing lke maintenance free tripot jell earthing, Plate earthing, Pipe earthing, Led Strip earthing for rocky areas.

The main objectives of the earthing are to:

1. Provide an alternative path for the fault current to flow so that it will not endanger the user
2. Ensure that all exposed conductive parts do not reach a dangerous potential
3. Maintain the voltage at any part of an electrical system at a known value so as to prevent over current or excessive voltage on the appliances or equipment.

The qualities of a good earthing system are:

1. Must be of low electrical resistance
2. Must be of good corrosion resistance
3. Must be able to dissipate high fault current repeatedly

Workshop
Few topics generate as much controversy and argument as that of Lightning and Surge Protection of electrical and electronic systems. Poor practices in Earthing and incorrect application and selection of Lightning and Surge protection devices can be the cause of continual and intermittent difficult-to-diagnose problems in a facility, often resulting in lost production and equipment failure. This workshop looks at these issues from a fresh yet practical perspective and enables you to reduce expensive down time on your plant and equipment to a minimum by correct application of these principles. This workshop is designed to demystify the subject of Lightning, Surge Protection and Earthing and presents the subject in a clear, straightforward manner. Installation, testing and inspection procedures for industrial and commercial power systems will be examined in detail. Essentially this course is broken down into the methods used to prevent lightning entering a facility such as dissipation arrays and those that divert surge energy away from sensitive equipment. Dissipation systems are discussed with associated earthing systems. Surge protection devices (surge arrestors) are dealt with by discussing the unique properties of the different devices to enable the delegate to select the correct device suited to the application required. Earthing and surge protection for Telecommunications and IT systems are examined in detail. Finally, the impact of lightning is examined and simple techniques for minimizing its impact described.
