The boiler produces steam. When we use a small portion of this pressurized steam to create draught in the boiler, it’s called steam jet draught. Because the steam itself creates the draught, there is no need for extra electric power to run draught fans, reducing system costs. Steam jet draught is a straightforward and cost-effective … Read more
Core and Windings of Three Phase Core Type Transformer There are different types of windings used for different kinds of applications and arrangements. Windings are the conductors wrapped in various forms like helical, disc, cylindrical, crossover which generates MMF that is carried by the core to other windings for having the different levels of voltages. … Read more
Electrostatic precipitators are common in thermal power plants due to growing environmental concerns. An electrostatic precipitator uses a high-intensity electric field to ionize dust particles in the air, which are then collected by oppositely charged collectors (electrodes). These dust particles are periodically removed from the collector plates by various mechanisms, such as hammering. Every device … Read more
Electrostatic precipitators are now standard in industries due to strict regulations and rising air pollution. Installing them in thermal power plant or any other power plants where flue gases are released is necessary. Measuring their efficiency determines if they perform as expected. Different industries have varying efficiency requirements. We’ll explore how to find the efficiency … Read more
What is a Ceramic Capacitor? A ceramic capacitor is the most commonly used capacitor in an electronic circuit. A ceramic capacitor is used due to its small physical size and large charge storage capability. The ceramic capacitor gets its name from its use of ceramic as a dielectric medium. Ceramic capacitors are known as the … Read more
A Zener diode is defined as a specially designed diodes that works mainly in reverse bias conditions. These diodes are more heavily doped than ordinary ones, giving them a narrow depletion region. Unlike regular diodes that get damaged when the voltage exceeds the reverse breakdown voltage, Zener diodes function in this region. The depletion region … Read more
“Maintenance” as the name suggests it is the action necessary for retaining or restoring a piece of equipment or machine to the specified operable condition to achieve its maximum useful life. Maintenance can be classified into two groups: Maintenance is defined as any action that increases the life of equipment and helps it run more … Read more
A rotor is the rotating part of an electrical machine, where current is induced by a rotating magnetic field through transformer action. Induction motor rotor is of two types: Squirrel Cage Rotor In this type of rotor, the rotor winding consists of conductors, in form of copper or aluminum bars embedded in semi-closed slots of … Read more
Before diving into the tuned collector oscillator, let’s understand what is an oscillator. An oscillator is an electronic circuit that generates an oscillating signal, like a sine or square wave. It converts a DC signal into an AC signal and is used in devices like TVs, clocks, radios, and computers. One of the simplest LC … Read more
An operational amplifier or op amps is a linear device used for ideal DC amplification. It is fundamentally a voltage amplifying device that works with external feedback components like resistors or capacitors. An op amp has three terminals: inverting input, non-inverting input, and output. As you can see from the diagram, op amp has three … Read more
