A turbine is a device which converts the energy of some fluid into rotational mechanical energy. There are a number of turbines available based on the type of input fluid used such as steam turbine, water turbine, gas turbines, etc.In this article, we will discuss about Francis turbine and Kaplan turbine and the key differences between them. Both Francis turbine and Kaplan turbine are types of water turbines, where the hydraulic energy of water is converted into mechanical energy (rotation of turbine). Basically, both Francis and Kaplan turbines come under the category of reaction turbine, which means in both cases, ... Read More

A synchronous generator, also called alternator, is a most widely used electric generator that produces alternating current supply. It is the main component of every power generating station. Based on the rotor construction, the synchronous generators are of two types namely − Cylindrical Rotor Synchronous Generator Salient Pole Rotor Synchronous Generator However, both types of generators are similar in stator construction. The stator of both types of generators consist of a three-phase winding distributed over its inner periphery. In this article, we will explain the key differences between cylindrical rotor and salient pole rotor synchronous generators along ... Read More

A transformer is a static electrical machine that is used for increasing or decreasing the value of alternating voltage or current. Based on the applications, the transformers are classified into following main types − Power transformer Distribution transformer Instrument transformer The instrument transformers are used for the protection and measurement purposes in the electrical power systems and are further classified into two types viz. current transformer (CT) and potential transformer (PT). In this article, we will explain the differences between current transformer and potential transformer along with their basic description. What is a Current Transformer? A current ... Read More

Both cell and battery are the sources of electrical energy in any electrical circuit that provide necessary excitation to the circuit. The cell and battery always deliver electric power to the circuit in the form of direct current (DC), they can never deliver alternating current (AC). Therefore, in practice, the cell and battery are the primary sources of direct current (DC) electricity. However, the working principle of both cell and battery is the same, i.e. electrochemical reactions where the electrical energy is converted into chemical energy and vice-versa. In this article, we will compare cell and battery by considering ... Read More

Both capacitor and supercapacitor are passive circuit components that store electrical energy in the form of electrostatic charge. Thus, the primary function of capacitor and supercapacitor is the same, i.e., storage of electric charge. However, there are many difference between a capacitor and a supercapacitor.In this article, we will discuss the key differences between capacitor and supercapacitor by considering various parameters such as definition, construction, types, energy density, etc. But before that we should learn the basics of capacitor and supercapacitor so that it becomes easier to understand the differences.What is a Capacitor?A capacitor is a two terminal passive circuit ...

Electrical power is produced at the generating stations which is then transported to the points of utilization with the help of electric power lines. The electric utility companies install two different types of electric power lines viz. transmission line and distribution line for conveying the electric power from power plant to consumer’s premises for utilization.This article is meant for describing the key differences between transmission line and distribution line. We also briefly explained that what the transmission line and distribution line are.What is a Transmission Line?Transmission lines are the power lines that carry the electric power at high voltage from ...

An electric power plant, also called generating station, is a setup that is used for generating electrical power. A power plant consists of a number of alternators (AC generators) which are driven by the prime movers such as IC engines, steam turbine, gas turbine, etc.The energy from some source such as steam, water, burning of fossil fuels, nuclear reaction, etc. is given to the prime mover, it starts rotating, and in turn rotate the alternator to which it is coupled. The alternator coverts this mechanical energy of rotation of turbine into electrical energy, which is then transmitted for the utilization.Based ... Read More

Electricity is nothing but a form of energy. The electricity is caused by the electric charge, where the charge is a property of subatomic particles such as electrons and protons. The electrons carry negative charge while the protons carry a positive charge.Technically, electricity is the phenomenon which involves either accumulation or movement of electric charge. Therefore, based on these two parameters (accumulation and movement of charge), the electricity can be of two types viz.Static ElectricityCurrent ElectricityIn this post, we will highlight all the significant differences between static electricity and current electricity by considering various factors such as basic definition, cause, ...

A Power Plant is a setup of various equipment which are connected together to produce electricity. However, there are many technologies evolving day by day to produce electricity, two of them that produces electricity from solar power are solar power plant and solar thermal power plant. A solar power plant is also called a solar photovoltaic power plant.In this article, we will describe the differences between "solar power plant" and "solar thermal power plant". But, before highlighting their differences, we will see what a solar power plant and a solar thermal power plant are.What is a Solar Power Plant?An arrangement ... Read More
