Air Insulated Electrical Substation Design
substations are the most common type of substation that you will find on the
electrical network, due to their cost effectiveness and simplicity.
This course will
give you an appreciation of how to design this type of substation and introduce you to all of the equipment’s that you will find in a typical air insulated substation
Air Insulated Substation Design
Air insulated substations are the most common type of substation that you will find on the electrical network, due to their cost effectiveness and simplicity..
This course will give you an appreciation of how to design this type of substation
Air insulated substations contain various types of equipment to provide a fully functioning system.
This includes conductors and clamps to connect the equipment's together, circuit breakers to switch the power on and off and transformers to change the system voltage.
By the end of this section you will know all about the main equipment's they use and their purpose inside the substation.
Inside the air insulated substation we need to interconnect all of the equipment's together in a safe and cost efficient manner.
To do this we use conductors & busbars to carry the electrical energy between the equipment's, connectors & clamps to join the conductors together and insulators to prevent the electricity leaking out to the grounded structures
By the end of this section you will understand the different types of equipment's that we use inside the air insulated substation to carry the electrical energy safely through the substation.
Insulators are used widely inside air insulated substations to keep personnel safe and prevent the electrical energy leaking out.
By the end of this section you will know all about the different type of insulators we use inside air insulated substation and learn about what the creepage distance is how it affects the design of the equipment's inside the substation
The network designer has numerous options on how to connect the incomers, busbars and feeders together to create a fully functioning substation
This section introduces some of the main configurations that we use to connect these elements together.
By the end of this section you should know the main network configurations that we use and understand the benefits and disadvantages of each
Circuit breakers used on air insulated substations come in all shapes and sizes and in this part 1 of this two part section we will introduce the principles behind dead tank circuit breakers.
By the end of this section you will understand the basic features of a dead tank circuit breakers and how the circuit breaker contacts break the electrical arc under both normal and fault conditions.
In part 2 of this section on circuit breakers we will take a further look into the design of high voltage circuit breakers with a particular emphasis on live tank circuit breakers.
By the end of this section you will understand all about the insulating mediums that we use inside the contact chamber, how live tank circuit breakers operate and what additional features we need on extra high voltage circuit breakers.
Metalclad switchgear is one of the most popular types of air insulated switchgear that we use on the distribution network.
In this section we will look at all of the important aspects of this type of switchgear and how it is designed to operate safely under all conditions.
By the end of this section you will know all about vacuum contact bottles, circuit breaker trucks and the enclosures that house them.
Circuit breakers are used in the network to switch the electrical energy on and off.
Sometimes we also need to insert some physical barriers into the network so that we know that the electrticity cannot flow into some parts of the network, to do this we use electrical isolators.
By the end of this section you will know why we use isolators inside air insulted substations and appreciate all of the different types of isolators that you will come across.
Safety is the main priority for all electrical utilities and protecting personnel from the dangers of electricity, whilst they are working inside the substation is essential
To do this we use grounding equipment's to make sure that when equipment is being installed, modified or maintained the electrical energy is rendered harmless.
By the end of this section you will understand why we need to ground the equipment's and look at the equipment's that we can use to do this in a safe and controlled way.
Air insulated substations use air as an insulating medium, and therefore need to be designed carefully so that the electrical energy that passes through them is controlled and kept safe.
To do these we space the equipment out using electrical clearances.
By the end of this section you will understand what the main electrical clearance parameters are, and how they are used to design the substation.
