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…

Every once in a while, a surge in electric current occurs and threatens to destroy valuable items. The electricity surge might last from a few seconds to days, depending on its causes. Also, the surge can range from a few millivolts to kilovolts. Both time and range of surges are essential considerations when considering what…

Urban areas and densely-populated towns in the US are often powered via gas-insulated substations, but what are they and what are they used for? Let’s take a look. What Are Gas-Insulated Substations? Gas-insulated substations (GIS) are high-voltage substations that contain major conducting structures within a sealed environment. Gas-insulated substations also contain an insulating medium, which…

As a concept and as a sustainable solution, energy storage has been around for decades. Countries like the United States have seen rapid growth in clean energy generation, with much of the increase influenced by legislative initiatives that reward renewable portfolios with financial incentives. On both federal and state levels, a growing number of business…

The demand for electricity is on the rise across multiple industries and locations around the globe. A grid is a network that interconnects between production, transmission, and consumption of electricity and plays a crucial role in the distribution of power to consumers. The conventional methods of storing and producing electricity have operated on the basis…

In order to power buildings, generators, and substations, electricity needs to be transmitted from one location to another. These electrical power transmissions have to move a considerable amount of electricity around from a source, such as a power plant, to a substation where it can be harnessed, transformed, and pushed through to consumers and other…

The production, transmission, consumption, and storage of electricity are changing, with increased demand and supply of renewable energy from multiple sources. The grid of the future must adapt to cope and sustain electricity transmission. Emerging technologies are shaping and disrupting the reliance on the current energy grids. Adaptable Grids Are the Future Grids of the…

An arrestor, also known as a surge arrestor, is an electronic device that regulates the voltage on equipment by redirecting large flows of current through an alternate circuit to the earth. By channeling huge surges of power to the ground, arrestors are able to protect electronic equipment and electrical systems that are not designed to…

Advanced Metering Infrastructure (AMI) is driving innovation in the modern grid in a number of ways. An AMI is a two-way system for communicating and collecting detailed information for utilities such as electricity. AMIs allow for real-time, automated readings that let customers and professional utility providers get a better picture of usage and peak times.…
