What does 220 kV substation mean?
220kV substation equipment. This is accomplished by suitable apparatus called Substation. For example, generation voltage (11KV or 6.6KV) at the power station is stepped up to high voltage (say 220KV or 132KV) for transmission of electric power. The assembly of apparatus (e.g. transformer etc.)
How many types of outdoor substation are there?
The outdoor substations are mainly classified into two types, namely pole-mounted substation and foundation-mounted substations.
What is the meaning of 33 11 kV?
Thus, when a substation is of rating 66/11 kV, means substation has been designed to receive 80 MVA on 66 kV and it will distribute the received power on 11 kV. Again, substation of rating 33/11kV means, the substation has been designed to receive 5 MVA of power at 33 kV and it will distribute the same on 11 kV.
What are the advantages of underground substations?
Underground substations Underground substations help to bring high voltage electricity directly into the city center. The stations are environmentally friendly, almost unnoticeable, and have none of the planning problems encountered by surface-built solutions.
What is an electrical substation?
An electrical substation is an assembly of electrical devices that are installed to control and protect the transmission and distribution power system. The substation has different types of transformer and several switching, controlling, and protecting types of substation equipments.
What is a step-up substation?
The step-up substation helps to increase or step up generating voltage level (from 11 kV up to 220 kV). It is constructed for a powerhouse or power station. From the step-up substation, 220 kV voltage is received to the primary grid substation. This voltage is transmitted over a three-phase three-wire of the overhead system.
What is urban transformer substation?
The concept enables transformer substations to be integrated into any urban environment – underneath other buildings or building complexes such as shopping malls or in multi-storey car parks, beneath parks, sport stadiums and public squares as well as intersections or roundabouts. Gas-insulated, high-voltage switchgear (GIS)
