Different Types of Substations

A substation is an electrical system with high-voltage capacity and can be used to control the apparatus, generators, electrical circuits, etc. The Substations are mainly used to convert AC (alternating current) to DC (direct current). Some types of substations are tiny in size with an inbuilt transformer as well as related switches. Other types of substations are very huge with different types of transformers , equipments, circuit breakers, and switches.

The different types of substations mainly include Step-up Type Substation, Step-down Transformer, Distribution, Underground Distribution, Switchyard, Customer Substation, and System Station.

Some of the substations are classified based on the nature of duties, service rendered, operating voltage, by importance and design.

• The nature of duties based substations are step-up, primary grid substation, step-down.
• The service rendered based substations are service rendered which includes a transformer, switching and converting substations.
• The operating voltage based substations are high voltage, extra high voltage, and ultra-high voltage substations.
• The importance based substations are grid and town substations.
• The design based substations are indoor, outdoor, foundation mounted and pole mounted substations.
