The rotating machines function on the same principle of electromagnetic induction those are the motor and the generator. Even though the principle is the same their the output they deliver differs due to the operational difference. This difference in operation is important for the machines to be classified as either a motor or a generator. Similarly, the individual machines can also be classified as ac or dc typed depending on the input and output they … [Read more...]

AC Generator – Functions, Advantages & Purposes
An Electrical Generator is a machine that converts mechanical energy into electrical energy. This machine is further classified into two other kinds based on the power supply i,e ac and dc. The basic difference name a generator as an ac or dc is its input power supply. If the supply to the machine is single directional then it is Dc and it is vice-versa if it is alternating. The internal operation differs with this input supply. Let us discuss in detail … [Read more...]
DC Generator – Construction, Working & Applications
An electrical generator is a machine that converts mechanical energy into electrical energy. It works on the principle of electromagnetic energy conversion. When a mechanical domain is given to the machine it develops a magnetic field that is further converted into electrical energy. Initially, mechanical energy to the machine is given by a prime mover. Due to this input current passes through the windings which develop the magnetic field. This magnetic … [Read more...]
Classification of Single-Phase Induction Motor with Applications
The steps began for the introduction of induction motor in the year 1892. Earlier it was made to run under 60 HZ power supply in 1893. This was made practically possible by Westinghouse. Later investigations have been conducted to work these type of motors under two-phase supply. The multi-phase supply produced much better advantages than single-phase. The disadvantage of one-phase is, it cannot self-start while the three-phase motor can self-start. The … [Read more...]
Single Phase Induction Motor – Function and Uses
The operation of the Single-phase induction motor can be done through a single power phase and used in domestic as well as industries. The main characteristic of this kind of motor is the same as that of a three-phase. This motor starts automatically (self) but a 1-phase Induction motor will not start automatically because it cannot expand starting torque. 3-phase expands starting torque through a rotating magnetic field. An AC motor starts through an … [Read more...]
What is an Induction Motor – Principle, Working & Types
Induction motor is a machine that simply operates on the induction type principle. It was invented by the scientist Tesla who earlier conducted several experiments on the working of the alternating current systems. Later, several experiments have been done to improve the performance of this type. This led to the inventions of the induction type of generator. But this type has limited access due to some of the cons than the pros of this generator. However, … [Read more...]
What is a Cooling Tower – Types, Working, Uses
Generally, in a steam power plant, boilers are used for the production of steam by heat water. The heated water is converted to steam which in turn converted to Electrical Energy by rotating a turbine. The steam generated after this operation instead of exhausting to the atmosphere can be reutilized. For utilization, we depend upon the process of condensation. The steam generated is sent to a cooling tower to convert the steam into cold water. The data of … [Read more...]
Fire Tube Boiler – Types, Operation & Uses
Steam boilers were used earlier for the production of steam in trains. Later on, with the development in the construction of these boilers, these boilers are classified into different types based on the generation of steam. The steam generated should be of high pressure in order to increase efficiency. So, to generate more steam, steam boilers are classified as water tube and fire tube boilers. The water tube boiler generates more steam of high pressure … [Read more...]
What is a Water Tube Boiler – Explain its Construction & Working
A Boiler is a device that produces steam by boiling water. This boiling of water is classified into different to the machine. The steam from the boiler in turn rotates a turbine such that it drives a generator. This generator changes this rotational ME to EE. The amount of energy that is developed in this process to supplied to the bus bars. From Bus bars the energy is transmitted to several other areas through the transmission lines. In this article, we … [Read more...]
What is Power Factor – Importance, Methods Used to Improve It.
The generated power in a power system should be utilized without wasting. The amount of power that is generated at the station is not received at the end point because of wastage of power. This wastage of power is mainly because of the reactive power absorption. This affects the power factor (pf) of the system. To increase the reliability and life expectancy of the system this pf plays a crucial role. To utilize the maximum amount of power that is … [Read more...]
