It is carried out by tap-changing on the HV side of the transformer. The number of turns on the winding is increased or decreased by a number of turns to make the secoondary voltage take the right value.
Tap-changing is done on the HV side because each turn is a smaller percentage of the voltage, which permits finer adjustment.

Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
What voltage is used for control circuits?
voltage
What is a 132 kv substation?
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 AnswerIn 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.
What should be the minimum recommended value of power factor of a substation?
A substation is not a load but is a place where switching and voltage-level changing takes place. Accordingly, you cannot apply a 'power factor' to a substation.
What is an injection substation?
An injection substation is a substation where a higher voltage is stepped down to a lower voltage,especially for transmission in a densely populated area.The transformer involved is often in the MVA range,so that the output can serve a wide area,or large consumers. In Nigeria,the common injection stations are: 15MVA or 7.5MVA 33/11kv injection substations.

Why the capacitive voltage transformer and voltage transformer both are used in a substation?
three phases

What is a mini-substation?
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
Why used transformer in subststion?
The substation is there to convert a high voltage to a lower voltage for electricity supply. Transformers are needed to do this.
What is mean of EHV substation?
Extra High Voltage substation. It generally 132 kv or higher
Why substation is called so?
The noun substation has one meaning - subsidiary station.It is a location where electricity is transformed or stepped down to lower voltage for distribution on intermediate voltage trunks.
What is function of CVT in Substation?
Capacitive voltage transformer (CVT) which is having special properties & used for protection & metering purpose.

What is green field substation?
In my line of work that is an Electrical High Voltage substation that is brand new. It is being built from a green field into an energized fully functional substation yard. There is no existing substation or remodeling of an existing one being done.
What should be the minimum recommended value of power factor of a substation?
A substation is not a load but is a place where switching and voltage-level changing takes place. Accordingly, you cannot apply a 'power factor' to a substation.
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.
