The Functions of Substations inthe Distribution of Electricity

What is a Substation?Have you ever seen a

substation? In electricity, a

substation is an electrical

facility that houses someequipment and machinery to

regulate and distribute

electricity to consumers.

What is a Substation?As you should know,

electricity is not delivered

straight from the power

stations to the consumers.

It is a subsidiary station of

an electrical system which

uses voltage.

What is a Substation?Most substations are located

outdoors, normally enclosed by

wire fenced and with danger

and no trespassing sings towarn the public to keep away to

avoid high voltage electrical risks.

What is a Substation?In some residential and high

density areas, substations

may be housed inside

building to reduce noise

pollution from the humming

of large transformers.

What is a Substation?Some can even be found at top of buildings.

Substations are managed and operated by certain

level 1 ASP electricians, engineers and operators

who are all substation installation professionals.

The Functions of Substations

Substations are like trains

stations or airports where

people get on and off ships and

airplanes respectively whentravelling to far places. With this

analogy, we can learn how a

substation works.

The Functions of Substations

At substations where the

voltage is transformed from

high to low and vice versa.

Substation engineers use step-up transformers to increase the

voltage to high values.

substations also perform the following functions

Protection of the transmission and distribution systems

Regulate the transmission and distribution of energy

Ensure steady and stable flow of electricity to the consumers

Maintain system frequency within the targeted limits

substations also perform the following functions

Maintain adequate line capacity to secure power supply

Transmit data for control, protection and network monitoring

Control voltage

Limit power surges Determine energy transfer


11/16



A substation has

certain equipment and

machinery to help in

the transmission anddistribution of energy.

Some Important Components of a Substation

Lightning arresters

It protects the facility from voltage

surge. It also protects the powerpoles/towers, circuit breakers and

transformers from damage by

electrical storms.

These equipment

measures, regulate andswitch electrical

transmission within the

facility.

Switches and breakers


14/16




They are the largest single

component in a substation.These large, box-shaped

structures are connected to

multiple wires.

Transformers


15/16




They are an array ofswitches and they direct

power out of the facility.

Distribution bus

Substations are vitals

systems which help provide

our need for electricity. A

high voltage risk area, they

need to be serviced by

competent level 1 ASP

electricians, engineers and.
