What are tariff and term involved?
Tariff In simplest terms, a tariff is a tax. It adds to the cost of imported goods and is one of several trade policies that a country can enact. A tariff is a tax on imports or exports. Money
What is reactive power?
Reactive power is a quantity that is normally only defined for alternating current (AC) electrical systems. This power goes up and down around some “average” value – this average value is called the “real” power and over
What are technical losses
Technical Losses Technical losses in power system are caused by the physical properties of the components of the power system. The most obvious example is the power dissipated in transmission lines and transformers due to internal electrical
What are losses in the transformer
Losses in transformer An ideal transformer has no energy losses i.e zero losses and 100% efficient. but in real (In practical) transformers, energy is dissipated in the windings, core, and surrounding structures. Larger transformers are generally more
What is dry type transformer
Dry type transformer as its name dry type means it does not require oil or any other liquid to cool the electrical core and coils. The purpose is served by normal air ventilation. In India, dry type
Amorphous transformers
The amorphous transformer is conventional transformer use the core of silicon steel laminations with an almost uniform crystalline structure i.e. CRGO. Amorphous transformers employ the core of amorphous steel which has lower hysteresis losses. Amorphous alloy: Metal
Advantages and disadvantages of an amorphous metal transformer
Advantages of amorphous metal in the transformer Less no-load losses: No load losses are 20 to 30% less as compared to a conventional silicon steel sheet transformer which keeps occurring for the lifetime despite transformer load. Easy
What are energy efficient motors
Energy efficient motors Energy efficient motors are motors in which improvements in the design are assimilated so as to increase the efficiency more than the standard motor. Design improvements in energy efficient motors mainly target reduction in
Electronic regulators
Energy conservation techniques in a fan, electronic regulators : Conventional fan regulators incorporated resistors in it for the speed control. Lesser amounts of current flows lesser amounts of current flow through fan and remaining passes through the
Classification of energy sources
Classification of energy sources can be as given below : Types of energy source Description Example Primary energy sources These are the sources which can be directly founds in nature or stored in nature and can be
