Substation Earthing

There are three reasons for which we use substation earthing. To earth the neutral point of the system. To earth, the overvoltages created due to lightning and switching impulses. From the safety point of view, …

Overhead Conductors

The wires through which electricity can flow are called electrical conductors. The conductors are mainly made of Copper and Aluminium. The conductors are mainly manufactured by hard-drawn processes. All the hard drawn process reduces the …

Electrical Insulators

The one and only work an insulator is to keep a live conductor electrically separated from the earth. The main material used for making is a solid insulator is either porcelain or glass. Although porcelain …

Electric Transmission Towers

For supporting extra-high-voltage or EHV overhead transmission lines, steel towers are used. These are also called lattice towers. Electric Transmission towers are constructed with GI (galvanized iron) angles of different sizes. The angles are assembled …

Overhead Line Supports

Types of Overhead Line Supports We can divide overhead line supports in two categories. They are poles and towers. The function of overhead line support is to keep the overhead conductors at a certain safe …
