132kV substation is part of transmission and distribution of power in which the transmission voltage is 132kV. The substation is for stepping down or stepping up of the voltages to the required voltage. the substation also serves as a place where the transmission lines can be isolated, controlled and monitored. The substation consists of different equipment that is used to regulate, monitor and distribute the required power.
Another Answer
In the UK, 132 kV voltages are considered to be the lowest transmission voltages. Other transmission voltages are 275 kV and 400 kV. A '132-kV substation' is normally one in which this voltage is stepped down to a primary distribution voltage, usually 33 kV but, sometimes, 66 kV. As the previous answer points out, substations contain Transformers, switchgear, busbars, and protection equipment.

How much min BDV of oil in transformer is required when charged it first time in 11kv 66kv and 132 kv of transformer?
The minimum Breakdown Voltage (BDV) of transformer oil required typically varies based on the voltage level of the transformer. For 11 kV transformers, a minimum BDV of around 30 kV is usually acceptable. For 66 kV transformers, a BDV of approximately 50 kV is often required, while for 132 kV transformers, it should be at least 60 kV or higher. Ensuring adequate BDV is crucial for the insulation performance and reliability of the transformer.
Why 198kV lighting arrester used in 220kV substation?
A 198 kV lightning arrester is used in a 220 kV substation to provide overvoltage protection by limiting the voltage surges caused by lightning strikes or switching events. The arrester's voltage rating is selected to ensure it operates effectively within the system's voltage levels while providing a safety margin to prevent damage to equipment. This choice balances the need for protection and the operational characteristics of the substation, ensuring reliability and safety in the high-voltage environment.
Why Indian power system in multiples of 11kv?
Multiples of 11 kV are used in many countries. The idea is to deliver a round number of volts so you add on 10% to allow for line losses. So 10 kV becomes 11 kV. In practice lines are operated without a 10% voltage drop now because it represents an unacceptable waste of energy, but we have stuck with 11 kV etc. Common supply voltages used for area distribution are 6.6 kV, 11 kV, 33 kV, 66 kV and 132 kV.
Why the generation voltage is 11kv not 10kv?
Alternator output voltages are typically restricted to around 25 kV to limit their physical size and the centrifugal forces to which they are subjected. In the UK, this voltage is then typically raised to 400 kV for transmission.The voltages to which you are referring to are typical of the voltages used in the UK's high-voltage distribution system. 'Grid' substations typically transform transmission voltages of 132 kV down to 33 kV (or, less commonly, 66 kV), and 'primary' substations then transform distribution voltages of 33 kV down to 11 kV.
What are the distribution voltages rated at between 400kV to 240V in Great Britain?
In Great Britain, the distribution voltages are typically standardized at several levels, with the highest being 400 kV for transmission. The common distribution voltages below this level include 132 kV, 66 kV, and 33 kV for primary distribution, followed by secondary distribution voltages of 11 kV, 6.6 kV, and finally down to 400 V for three-phase supply and 230 V for single-phase supply used in residential settings. These voltages are part of the UK's electrical system to ensure efficient transmission and distribution of electricity.
What is the capacity of power transformer for 132kva substation?
A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.

What is grid substation?
this type of substation are considered important because any sort of disturbance in these substation may lead to the failure of grid.this type of substation are used to transmit huge amount of power from one point to other point in the gridAnswerA substation is a location where electricity transmission/distribution voltage-levels are changed and switching is carried out, as opposed to a power station, where electricity is generated. A substation, therefore, is a yard/building in which there are transformers, switchgear, busbar systems, and protection systems.A grid substation is part of the electricity grid system -i.e. part of the transmission system. In the UK, this involves voltage levels of 400 kV, 275 kV, and 132 kV.

Why only 11kv is used in power systems transmission line?
It isn't. In the UK, transmission and distribution voltages are 400 kV, 275 kV, 132 kV, 66 kV, 33kV, and 11 kV.
What is the difference between the single line diagram of a 33 kV substation and a 66 kV substation and if possible then please provide the S.L.D. of both substations?
basically there will not be any difference between them. the capacity of equipment will be more such as the CB rating will be more basically there will not be any difference between them. the capacity of equipment will be more such as the CB rating will be more
Why do you represent the voltages ranges in terms of 11kilo Volt in power system?
It used to be a convention to add 10% to allow for transmission losses, so the voltages were always described as 11 kV, 33 kV, 66 kV and 132 kV. Later standards in the UK grid are 275 kV, which is a multiple of 11, and 400 kV which is not.
Is there a induce voltage on the human being in the 220 kilovolts substation?
yes,, because, the diaelectric strength of air is 35 kv/cm, above it, air start conducting. at 220 kv current wil start flowing through human body.
