Site Selection of a Grid Substation The site selection of a Grid Substation is the first and most important activity. This needs meticulous planning, foresight, skillful observation, and handling so that the selected site is technically, environmentally, economically, and socially optimal and is the best suited to the …
Electrical Faults are abnormalities of electrical parameters, either voltage or current, or both in a stable power system. Electrical faults are generally caused by equipment failure, human error, and environmental conditions. Electrical faults can cause significant economic damage and have the potential to cause fire hazards risking human …
Bus bar The bus bar is a common conductor/group of conductors where all incoming and outgoing feeders connect. It collects the incoming electrical power and distributes it to the outgoing circuits. We can say it works on Kirchhoff’s current law. The bus bar is used at all voltage-level …
A GIS or gas-insulated switchgear substation is a compact, metal-enclosed structure that houses high-voltage switchgear, busbars, and other electrical equipment. Unlike conventional Air Insulated Switchgear (AIS) Substations, which use open-air configurations, GIS substations utilize sulfur hexafluoride (SF6) gas as an insulating medium within metal-enclosed units. This design not …
Air insulated Switchgear or AIS Substation is a type of substation where all electrical switchgear and other high-voltage equipment’s insulation to earth and between phase conductors are mainly provided by air at atmospheric pressure and where some live parts are not enclosed. Working Principle The basic working principle of …
Substations are part of an electrical power system which plays a very important role in the generation, transmission, and distribution of electricity. It serves as an intermediary point between the source and load distribution networks. The main functions of substations include voltage transformation, switching, and protection of the …
