Substation main components include the following:
1. The power transformer which is the heart of the Substation. It is the Power transformer that steps up (in the case of a step up Substation for transmission) or steps down (in the case of step down Substation for distribution) the voltage e.g. 132/33kV (step down), 33/132kV (step up).
2. The Auxiliary transformer (which is fed from the output of the Power Transformer). This transformer powers the substation accessories and auxiliary equipments such as controls, lighting, Substation control room etc)
3. Disconnecting switch or Isolators
4. Earthing switch for grounding the main line in case there is need for maintenance work
5. Control relays and Protective relays for short circuit, over voltages etc
6. Instrument Transformers e.g. voltage transformers, current transformers that will take current from the main high voltage line in case of an over current on the line and produce a current that the protective relays can operate with.
7. Supervisory Control and Data Acquisition (SCADA) systems for line monitoring and control
8. DC power supply system in the form of batteries for supplying DC loads such as emergency lightings, relays, rectifiers, chargers etc.
9. Lightning arrestors
10. Surge arrestors
11. Switchgears for the high and low voltage levels, AC/DC panels
12. Circuit breakers for the high and low voltage levels

What is a mini-substation?
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
What is tertiary bus in substation?
Many substation transformers have three windings - the primary, secondary, and tertiary. The tertiary bus is the bus connected to the tertiary of the transformer. this is often used as station power for the substation, since the tertiary is very often a distribution level voltage (2 - 15kV).
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.
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.
Function of dc battery at substation?
Batteries are essential components in a substation. They provide the (tripping) current by which protective relays can trip high-voltage circuit breakers in the event of a fault. This means that the circuit breakers can trip even if the substation itself has lost its ancillary AC power supply.
What is the function of Batteries in the substation?
a very helpful functionAnswerBatteries are essential components in a substation. They provide the (tripping) current by which protective relays can trip high-voltage circuit breakers in the event of a fault. This means that the circuit breakers can trip even if the substation itself has lost its ancillary AC power supply.

What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
What are the different types of relays used in substation?
kinds of electrical relays
When was Jefferson Substation created?
Jefferson Substation was created in 1909.
When was Neuhof Substation created?
Neuhof Substation was created in 1985.
What type of gas is used in a gas insulated substation?
sulphur hexa-fluouride
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 are the five electronic components used to build circuits?
I Know 4 of them: source, load, wire(s), and switch
What is tertiary bus in substation?
Many substation transformers have three windings - the primary, secondary, and tertiary. The tertiary bus is the bus connected to the tertiary of the transformer. this is often used as station power for the substation, since the tertiary is very often a distribution level voltage (2 - 15kV).
Why the capacitive voltage transformer and voltage transformer both are used in a substation?
three phases
