Parallel Operation of Transformer
Need for Parallel operation When load on the system is increased, it is easy to add more transformers to the system instead of replacing smaller transformer by larger ones. If the load on the system is decreased, one or two…
Transformers Tests
A number of tests are made on transformer to determine the voltage ratio, reactance of the windings, magnetizing current, core losses, copper losses, efficiency and temperature rise etc
Auto Transformer
An auto transformer has one winding only Part of this winding being common to both primary and secondary.
Tariff
The rate at which electricity is supplied to a consumer is known as tariff.
Gas Turbine Power Plant
In gas turbine power plant (GTPP) the fuel (Gas & Oil) is combusted in a combustion chamber in combination with the compressed air.
Diesel Power Plant
In these plants the chemical energy of fuel(petrol) is converted into mechanical energy with combustion in the cylinder of a diesel engine
Hydro Electric Power Plants: Harnessing the Power of Water
In hydro electric power station the water under pressured is directed to the hydraulic turbine. The water under pressured is obtained from a natural water fall in the pressure is produced from storage of water in a reservoir.
Nuclear Power Plant
Basically nuclear power plant is a thermal power station but a nuclear power station the heat required for converting water into steam is obtained by fission and not from combustion of fuel.
Thermal or Steam power plant
Thermal Or Steam Power Plants are those power plants that run on steam. In thermal power station fuel is burn and the is used to convert water into steam
Full-wave Controlled Center-tap Rectifiers
To build a controlled rectifier or a phase-controlled rectifier,the diodes in the rectifier circuits are replaced by SCR. These circuits produce variable DC o/p
Mobile Radio Propagation
The mobile radio channel places fundamental limitations on the performance of wireless communication systems.
Ni-Cd battery charger circuit
This circuit can be primarily used for charging 12V Ni-Cd battery packs. Any way 6V and 9V battery packs can be also charged
