Substations are the unsung heroes of the electricity grid. Electric substations are facilities that transform electricity into various forms for safe and effective transportation or distribution. But what exactly is a substation, and what does each type do? Below, we take a look at the different types of substations and the classification of substations. Transmission Substations Transmission substations either…

Circuit breakers are a form of electrical switching device that is implemented to regulate and protect electrical systems that are operated manually or automatically. These devices can be used to interrupt the current flow of electricity and prevent damage brought about by a short circuit or overcurrent. There are a few different types of circuit…

Substation maintenance is the process by which ancillary equipment, switchgear, and buildings in a substation undergo planned inspection periodically, with any necessary repairs being done. These regular preventative checks ensure that substation is kept in the best possible working order at all times. Read on to see why it’s critical to ensure that a substation,…

Power stations and systems make use of ‘transformers’ to get the job done; these components carry electrical energy between different circuits, changing the level of alternating current (AC). This makes them vital for the transmission of AC power across the world, with a variety of designs for various specialized applications across the board. One such…

An electrical substation has similar functions to the central station as it generates, transmits and distributes electrical power. As a result, it is also known as a secondary station. Its fundamental role is to change the voltage from low to high and vice versa. Over the years, safety measures have been established that go a…

Insulation plays an important role in a substation. If you’re curious about what an insulator is and want to know more about how it works, what materials make the best insulators, and more, read on. What Is an Insulator? An insulator in electricity is a material in which the electron cannot move freely. Their internal…

A substation needs to have a number of electrical equipment if it is to successfully transfer electrical power from the point at which it’s generated to the consumers. This equipment is assembled together in order to create a complete and functional substation. If you would like to know what this equipment is, read on to…

Current electrical power consumption is increasing quickly, and power-producing substations have the task of meeting this demand. A power substation refers to an electrical system with a high voltage capacity whose purpose may be for running equipment such as generators and electrical circuits, among others. The primary objective is to provide continuous energy or power…

Power transmission is the large-scale transportation of electrical energy from a generation source, such as a power plant. A transmission network is a collection of interconnecting wires that allow this movement to occur. This contrasts with the local cables that connect high-voltage substations to consumers, which is an act of power distribution. Towers supporting high-voltage…

A power transformer is an electrical device that converts alternating power from one voltage to another. Because there are no rotating or moving components a transformer is usually modeled as a stationary device. In the majority of cases, power transformers are used to “step down” voltage from a higher level to a lower level to…
