    Lightning arrester is a most important protective device of distribution substation to protect valuable equipment as well as working personnel. It arrests and discharges over voltage to earth during lightning strokes. These are installed between line and earth near equipment.It is the current which the fuse element can normally carry with over heating or melting.

    PPEs Required to Enter a Substation · Hard hats (with full/partial brims as necessary) · Safety glasses with side shields · Face masks/shields.Earthing leads are the link, which provides connection between the earth conductors and the earth electrode.

    Inside you find the brains of the station Protective relays that constantly monitor lines and equipment, keeping track of many voltages, currents, temperatures.In this system, only one additional breaker will be needed, thus its cost in comparison to single bus bar system will not be much.
