An electric power system or electric grid is known as alarge network of power generating plants which connected to the consumer loads. As, it is well known that “Energy cannot be created nor be destroyed but can only be converted from one form of energy to anotherform of energy”. Electrical energy is a form of.
The place where electric power produced by the parallel connected three phase alternators/generators is called Generating Station(i.e. power plant).
The electric supply (in 132kV, 220 kV, 500kV or greater) is transmitted to load center by three phase three wire (3 Phase – 3 Wires also known as.
At a sub station, the level of secondary transmission voltage (132kV, 66 or 33 kV) reduced to 11kV by step down transforms. Generally, electric supply is provided to those heavy load.
Area far from the city (outskirts) which have connected with receiving stations by lines is called secondary transmission. At receiving station, the level of voltage reduced by step-down Transformers up to 132kV, 66 or 33 kV, and.The electric grid of India, also known as the National Grid, is a high-voltage electricity transmission network that connects power stations and major substations across the country. It ensures that electricity generated anywhere in India can be used to satisfy demand elsewhere.
