Presently 3-ø AC system is very popular and being used worldwide for power generation, power transmission, distribution and for electric motors.Three phase system has the following advantages as compare to single phase system: Power to weight ratio of 3-øalternatoris high as compared to 1-ø alternator. That means for generation for same amount ofElectric Power, the size of 3-ø alternator is small as compare to 1-ø alternator. Hence, the overall cost of alternator is reduced for generation of sam

What is a Power System?An electric power system is defined as a network of electrical components used to supply, transfer, and consume electric power. The supply is done through some form of generation (e.g. a power plant), the transfer is done through a transmission (via a transmission line) and distribution system, and the consumption can be through residential applications such as powering the lights or air conditioning in your home, or via industrial applications such as the operation of lar

The connection of several generating stations in a network of particular transmission voltage level is commonly known as electrical grid system. By interconnecting different power generating stations we can solve various difficulties arise in power system. The structure, or “network topology” of a grid can vary depending on the the load and generation characteristics, constraints of budget and the requirements for system reliability. The physical layout is often forced by the geology and land av

A vacuum pump is a device that removes gas molecules from a sealed chamber or container, creating a partial or complete vacuum. Vacuum pumps are widely used in various industries and research fields, such as aerospace, electronics, metallurgy, chemistry, medicine, and biotechnology. Vacuum pumps can also be used for applications such as vacuum packaging, vacuum forming, vacuum coating, vacuum drying, and vacuum filtration.In this article, we will explain what vacuum pumps are, how they work, wha

Steam power plants are still the backbone of the total power generation in the Asia pacific. Thus even a small improvement in the form of increasing the efficiency has a tremendous effect on the fuel-saving and also a reduction in emission of greenhouse gases.Thus one should not miss out on any opportunity to find out the ways and means to increase the efficiency of the steam power cycle.The idea behind any improvement or modification is to increase the thermal efficiency of the power plant. Thu

Rankine Cycle with Closed Feed Water HeatersRankine cycle with closed feed water heaters are having its benefits and is most commonly used in all modern power plants. Closed feed water heater employs indirect mode of heat transfer, i.e extracted steam or bleed steam from the turbine transfers its heat indirectly to feed water in shell and tube heat exchanger. Since the steam and water are not mixing directly, so both steam and water circuits are at different pressures. Close feed water heater in

What is the Rankine Cycle?The Rankine Cycle is a mechanical cycle commonly used in power plants to convert the pressure energy of steam into mechanical energy through steam turbines. The Rankine Cycle’s major components include a rotating steam turbine, a boiler pump, a stationary condenser, and a boiler.A boiler is used to heat the water for steam at the required pressure and temperature as per the turbine’s requirement for power generation.The turbine exhaust is directed to the radial or axial

Carnot CycleThe Carnot cycle is a thermodynamic cycle that is known for the best possible efficiency. Carnot cycle changes the energy available in the form of heat to produce useful reversible-adiabatic (isotropic) and other processes.Carnot engine efficiency is one minus the ratio of the temperature of the hot thermal reservoir to the temperature of the cold reservoir. The Carnot cycle is known for setting the highest efficiency benchmark that any cycle or engine can achieve.Work is done by the

The objective is to develop the basics understanding of the following concepts: Internal Energy and First Law of Thermodynamics The cyclic and arbitrary process of a system Reversibility and Irreversibility Entropy and Enthalpy Second Law of ThermodynamicsInternal Energy and First Law of ThermodynamicsWhen the energy of a molecule within a system is associated with the property of the system, then it is termed as Internal Energy(u).Energy neither be created nor be destroyed and based on this pri

The fundamentals of engineering thermodynamics play an important role in moving towards a better world, through improvement in performance of the plant, equipment, and their overall design.Factors that are critical in assessing the performance of the equipment are items like the output of the final product, consumption of input raw material, production cost, and assessment of the effect on environmental. Engineers today are using the concept of thermodynamics to examine and reinvent things which
