High and Low Voltage Transmission
An electrical substation is a part of the electric energy conversion and distribution system. Substations are designed for all voltages for the purpose of converting voltage from high to low and in reverse.
Underground Cabling System
All around the globe, high-voltage and extra-high-voltage transmission make almost exclusive use of overhead lines. But the implementation of underground cabling system for power applications has more advantages over the overhead lines since the voltage drops are smaller and there are fewer chances of developing faults.
Switchyards is the inter-connector between power generation and transmission. It operates at a single voltage level and is placed outside the power station, delivering generated power to the nearest grid.
AC and DC Transmission Towers
Ever since the earliest examples of long-distance electric power transmission, overhead transmission lines have been the preferred method for transporting large amounts of electric power. Depending upon the requirements of the transmission system, AC and DC transmission towers are built to support the high-voltage conductors of elevated power lines.
