Air insulated substation design part 2

Air insulated substation design part 2

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.

In part 2 of this course we will look at some additional features of this type of substation.

The main with focus will be on transformers, we will learn all of the fundamental principles behind them including their rating, construction & design and them see how we design a substation to incorporate these critical equipments.

In substations it is essential that all circuit breakers, isolators and other switchgear each has a unique number to avoid confusion and ensure that the substation is operated safely. We will learn how a numbering system can be developed from first principles and how it can applied to various substation configurations.

Interlocking is used inside substations to ensure that primary plant can only be operated in a safe sequence, which ensures that grounded equipment is never energised from the live system and within its design parameters. We will look at the two main forms of interlocking, namely mechanical & electrical, and see how they can be applied to various common substation configurations.

Ring main units are used throughout the electrical network and we look at how these critical equipments are used and operated to improve the security of the electrical network.

By the end of the course you will have a better appreciation of all of these key substation systems.
