Provide the ground connection for connecting the neutrals of stat connected transformer winding to earth neutral earthing.Ī protective earth pe connection ensures that all exposed conductive surfaces are at the same electrical potential as the surface of the earth to avoid the risk of electrical shock if a person touches a device.Ī protective earth pe connection ensures that all exposed conductive surfaces are at the same electrical potential as the surface of the earth to avoid the risk of electrical shock if a person touches a device in which an insulation fault has occurred. The earthing system sometimes simply called earthing is the total set of measures used to connect an electrically conductive part to earth.Ĭonventional earthing the conventional system of earthing calls for digging of a large pit into which a gi pipe or a copper plate is positioned in the middle layers of charcoal and salt.Įarthing system a protective earth pe connection ensures that all exposed conductive surfaces are at the same electrical potential as the surface of the earth to.Įnsure safety to personnel in substations against electrical shocks.Įarthing system earthing for system protection uo un at least two main reasons amount many others areat least two main reasons amount many others are.ġ drainage of excessive high surge volatge especially the common mode disturbancesmode disturbances 2 preventing prolong high voltage of any phase become un against. Introduction in electricity supply systems an earthing system defines the electrical potential of the conductors relative to that of the earths conductive surface.
The choice of earthing system has implications for the safety and electromagnetic compatibility of the power supply. Lightning protection is an essential system for any construction and it is thus necessary to understand the design and usage of this system. In the earthing system put the earth electrode in vertical position underground as shown in the above fig.Īpplication note deals with the design of the ground electrode system while section 651 gives practical guidance on the design and calculation of ground electrodes. The functions of grounding systems or earth mat in include.
It requires maintenance and pouring of water at regular interval. Furse provides world leading earthing lightning and electronic systems protection from our own designed and manufactured products through to risk assessment and systems design advice.
