Air Blast Circuit Breaker is those kind of circuit breaker which operates in air at pressure of 20-30 kg/cm2. It is also good choice to avoid the risk of oil fire, in case of oil circuit breaker. The aim of all kind of circuit breaker is to prevent the re-establishment of arc after current zero by creating … Read more
Definition A generating station which utilizes the potential energy of water at a high level for the generation of electrical energy is known as a hydro-electric power station. Hydro-electric power stations are generally located in hilly areas where dams can be built conveniently and large water reservoirs can be obtained. In a hydro-electric power station, … Read more
A generating station in which nuclear energy is converted into electrical energy is known as a nuclear power station. In a nuclear power station, heavy elements such as Uranium (U235) or Thorium (Th232) are subjected to nuclear fission. in a special apparatus known as a reactor. The heat energy thus released is utilized in raising … Read more
A generating station in which diesel engine is used as the prime mover for the generation of electrical energy is known as diesel power plant or diesel power station. In a diesel power plant, a diesel engine is used as the prime mover. The diesel burns inside the engine and the products of this combustion … Read more

Thermal Power Station A thermal power station is a power plant in which the prime mover is steam driven. The operation of a thermal power station is such that the water is heated first, and turns into steam. This steam is used for rotating a steam turbine which drives an electrical generator. After passing through … Read more
Power quality refers to maintaining the near sinusoidal waveform of power distribution bus voltages and currents at rated magnitude and frequency. Power quality describes the extent of variation of the voltage, current, harmonics, and frequency of the power system. The poor power quality effects industrial competitiveness drastically and thereby impedes our efforts to turn into … Read more
A ground fault circuit interrupter (GFCI) is a device that cuts off an electric power supply when it detects the ground fault in the system and hence prevents the system from severe damage. The GFCI monitors the current flowing into different phases and neutral. It turns off the power supply by sending a tripping signal … Read more
When we talked about conventional thermal power plants the efficiency is in between 37 to 40%. In thermal plants, the fuel is burnt and the heat generated is used to convert water into steam. This steam is used to used to rotate turbine of an alternator. This is how steam energy is converted into mechanical … Read more
Due to the frequent increase in electricity tariff charged by the electric utility, poor reliability of electric supply, forced outages, long power cuts, etc., a large number of industries have switched over to their own generating station (plant) within their own campus. This method of generation is called Captive Power Generation and such plants are … Read more
