3 Stages of Power Supply
The electricity supply system is divided into three major parts: generation, transmission and distribution. Generation means ‘production’ of electricity at various types of power plants. Transmission means carrying the electricity produced at power plants over long distances at high voltages to locations near the point of actual use. Distribution involves actual delivery of power to the end users. (Distribution stage image source: https://bengaluru.citizenmatters.in/bengaluru-bescom-power-cut-transformers-poorly-maintained-metering-cstep-study-46438 ) Traditionally, electricity generation has been based on the effects of magnetism. When a conductor is exposed to a varying magnetic field, a voltage develops across it which depends on the rate of variation of the magnetic field. This is stated by the Lenz’ Law and Faraday’s Law. Several different types of power plants use this principle. Coal-fired thermal power plants burn coal to generate high-temperat...
