7 Main Components of a Distribution Substation

A distribution substation is a voltage regulation point that delivers electric energy from transmission systems to residential and industrial consumers. Power is transported from the distribution substation via distribution feeders to the premises of the end consumer.

Distribution substations are comprised of several components, each serving a critical role in delivering power to homes and businesses. In order to keep these components functioning properly, proper protection should be installed. Keep reading to learn more about distribution substation components and how Critter Guard can help provide uninterrupted power.

Main Components of a Distribution Substation

A distribution substation is made up of the following components:

  1. Supply Line: A supply line, commonly known as a primary feeder, is used to connect a distribution substation to a sub-transmission system.
  2. Transformers: Transformers are used to step-down the supply line voltage to distribution level voltage. Three-phase transformers are generally used but the number can vary depending on the distribution substation design and the importance of the end consumer.
  3. Busbars: Busbars, also known as buses, are used for carrying large currents and distributing them to multiple circuits inside the switchgear.
  4. Switchgear: Switchgear is made up of primary switching, interrupting devices, as well as control and regulation equipment.
  5. Outcoming Feeders: Power from the substation to points of service is carried by outcoming feeders.
  6. Switching Apparatus: Fuse, switches, service protectors, and circuit breakers make up the switching apparatus. These are used to connect or disconnect the system power elements to or from other system elements.
  7. Surge Voltage Protection: Surge voltage protection is used to protect power systems from overvoltage.

How Critter Guard Can Help Protect Substations From Critter Damage

At Critter Guard, our Line Guard and Pole Guard products are made to protect powerlines and substations from critter interference. These products deter squirrels, birds, and other animals from accessing data communication lines, electric power lines, transformers, and substations, resulting in efficient power flow and less loss of life for wild animals.

Having steady and efficient power supply is a basic necessity for many. To learn more about our humane wildlife control products and how they can protect distribution substations from critter interference, contact us today!
