Electrical Power Transmission might be just the transportation of Power from its point of generation to the points of distribution, but the art of making that process seamlessly efficient and smooth is where our expertise lies.

At PRISM, when we take upon ourselves the movement of power through the grid lines, we are not only transporting just POWER. We are transporting Quality and Reliability.

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines which facilitate this movement are known as a transmission network. The combined transmission and distribution network is known as the “power grid” or the “National Grid”.

Most transmission lines are high-voltage, three-phase alternating current (AC). High-voltage direct-current (HVDC) technology is used for greater efficiency over very long distances (typically hundreds of miles). HVDC technology is also used in submarine power cables (typically longer than 30 miles (50 km)), and in the interchange of power between grids that are not mutually synchronized.
Typically, Electric Power is transmitted using Overhead as well as Underground Cables. Electricity is transmitted at high voltages (115 kV or above) to reduce the energy loss which occurs in long-distance transmission. Power is usually transmitted through overhead power lines. Underground power transmission has a significantly higher installation cost and greater operational limitations, but reduced maintenance costs. Underground transmission is sometimes used in urban areas or environmentally sensitive locations.
