Earthing (or grounding) is an essential part of any electrical installation. Within industrial and pharmaceutical plants with potentially explosive atmospheres earthing plays an essential role in maintaining the electrical and instrumentation systems in safe condition. The earthing system, although a single physical system, it carries out many different functions including automatic detection and...
This paper discusses the ground window design concept. It integrates the earthing systems of equipment having different earthing needs. It provides a mechanism for reducing transient effects on sensitive equipments. It is also said that it is the imaginary hole in the IGZ (isolated ground zone) through which all electrical conductors enter or leave.
This paper presents an overview of earthed and unearthed electrical systems. Type of earthing systems, advantages, disadvantages, and applications of different systems, use of RCDs are also presented
This presentation discusses Mark Dekenah's consultations for electrical installations. Power quality and its role where sensitive microprocessor loads are used is also discussed. Neutral-Earth potential and Earth noise were discussed. And what is a "BALUN" and when is it applicable to used.
This paper is based one presented at the IEE BETNET conference in Hong Kong in October 2005, which itself was based on a paper given to an ERA Technology Conference in June 1997. The principles, if not the practice, involved in earthing an electrical system are the same regardless of the potential at which it operates. Earthing introduces hazards but allows fault currents to flow, which can be used...
