Star Delta Stater The star delta starter is widely used for the starting of a 3 phase induction motor. In star delta starting,the motor is first connected in star connections and after achieving the specified speed the motor is connected in delta connection. The small rating induction motor are often started on direct online… Continue reading How to make a star delta connection? What is star delta starter?
Working Principle of DC Generator We can see that within the half the revolution current always flows along ABLMCD, i.e., brush no 1 up-to-date with segment a. within the following half revolution, within the figure, the direction of the induced current within the coil is reversed. But at the identical time the position of the… Continue reading DC Generator | Working principle and Application
What is Contactor? The contactor is an electrically controlled switching device. It is used for electrical switching. The basic operation of this is often almost like a relay, but the sole difference is that contractors can carry large current compared to relay up to 12500A. They cannot provide short or overload protection but can break… Continue reading Types and Construction of Contractor
Battery Battery is the primary source of any gadgets such as electronics, wireless, smartphone, laptop, clock or remote etc. Are you able to imagine things without these energy sources? We wouldn’t be able to build any wireless device and need to believe wired power source only, even electric cars and space missions wouldn’t be possible… Continue reading Battery | Types of Batteries
Electric Motor The electric motor may be a device which converts electricity to energy . There are mainly three types of electric motor. DC Motor Induction Motor Synchronous Motor All of those motors add more or less same principle. The main function of electric motor depends on the magnetic flux with current. To understand this… Continue reading Electric Motor | working of DC Motor
What is cogeneration? Cogeneration may be a very efficient technology to get electricity and warmth . It is also called Combined Heat and Power (CHP) as cogeneration produces heat and electricity simultaneously. Cogeneration supplies currently 11% of electricity and 15% of warmth in Europe. Using a fuel to simultaneously generate heat and electricity with one… Continue reading What Is Cogeneration | What is CHP Plant
How do fossil fuel power plants work? A fossil fuel power station works similarly to a standard thermal station, except it burns gas rather than fossil fuels, like coal, to come up with electricity. What are power plants, and the way do they work? A power plant (also referred to as an influence station, generating… Continue reading What is Fossil fuel? How do fossil fuel power plants impact the environment?
Tidal Power Generation Tide or wave is periodic rise and fall of water level of the ocean. Tides occur because of the attraction of sea water by the moon. Tides contain great amount of mechanical energy which is employed for power generation. When the water is above the mean water level, it’s called flood tide.… Continue reading Working Principle of Tidal Power Plant
