How does electricity flow through a substation?

Between the generating station and the consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages.

How does a Generator Substation work?

This substation uses large transformers to convert or "step up" the generator's voltage to extremely high voltages for long-distance transmission on the transmission grid. Typical voltages for long distance transmission are in the range of 155,000 to 765,000 volts. The higher the voltage, the less energy is lost due to resistance [source: UCSUSA].

What voltage does a distribution substation operate at?

Go back to contents ↑ Distribution substations typically operate at 11KV/0.4KV voltage levels and deliver electric energy directly to industrial and residential consumers. Note that distribution voltage level may vary in countries worldwide. Distribution feeders transport power from the distribution substations to the end consumers’ premises.

What is a high voltage substation?

High Voltage Substations (HV Substations) (11–66 kV) High voltage substations, operating within the range of 11 kV to 66 kV, play a crucial role in the electrical power system. They act as intermediaries, converting high-voltage electricity from transmission lines into lower voltages that are suitable for distribution to consumers and businesses.

How many volts does an underground substation have?

Due to their complex designs, underground substations can accommodate various components such as transformers, switchgear, and protective equipment. These substations typically operate at voltage levels ranging from 34,500/19,920 volts to around 4,160/2,400 volts, depending on the area’s power requirements.

What are the different types of substations?

Substations can be generally divided into three major types (according to voltage levels): Transmission substations integrate transmission lines into a network with multiple parallel interconnections, so that power can flow freely over long distances from any generator to any consumer. This transmission grid is often called the bulk power system.
