For an individual generator that is rated above 1000 kW, and is to be used in the oil industry, it is usual practice to use a gas turbine as the driving machine (also called the prime mover). Below 1000 kW a diesel engine is normally preferred usually because it is an emergency generator running on diesel oil fuel.There are different types of gas turbine driven … [Read more...] about Types of Gas Turbine Engines

Video : How Does a Tesla Electric Car Work?
Electric cars are making big waves in the automobile world. These noise-free, pollution-free and high-performance vehicles are expected to make their I.C. engine counterparts obsolete by 2025. This video will unveil the hidden technologies behind the Tesla Model S, which recently became the world’s fastest accelerating car. We will see how electric cars have … [Read more...] about Video : How Does a Tesla Electric Car Work?
Voltage and Power Equations of DC Motor | Condition of Maximum Power
In this post, we will look at the voltage and power equation of a dc motor and the condition for maximum power in a dc motor. Voltage Equation of a DC Motor The voltage V applied across the motor armature has to overcome the back emf Eb and supply the armature ohmic drop IaRa . This is known as voltage equation of a motor. Back EMF and Its Significance in DC … [Read more...] about Voltage and Power Equations of DC Motor | Condition of Maximum Power
Core Type and Shell Type Transformers
Depending on the type of construction used, the transformers are classified into two categories. Core type Transformer Shell type Transformer Difference between Power Transformer and Distribution Transformer Core Type Transformer In core type construction, as shown in figure, the coils are wound around the two limbs of a rectangular magnetic core. Each limb carries one … [Read more...] about Core Type and Shell Type Transformers
Electric Potential, Potential Difference and EMF
In this article, you will study what are electric potential, the potential difference (pd) and electromotive force (emf) and the difference between them.Just as a body raised above the ground has gravitational potential energy, similarly, a charged body has electric potential energy. When a body is charged, work is done in charging the body. This work done is stored in the … [Read more...] about Electric Potential, Potential Difference and EMF
