Electrostatic precipitators are essential in thermal power plants and other power plants to reduce flue gas emissions. With growing concerns about environmental pollution, these devices have become a necessity. They use a high-intensity electric field to ionize dust particles in the air stream, which are then collected by oppositely charged electrodes. The collected dust particles … 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
Operational amplifier or Op Amp as they are generally called are linear DC amplifiers. An op amp is a three-terminal device, one called the inverting terminal, one non-inverting terminal and the other is called the output terminal. Below, you can see a pin diagram of a typical Op amp. An ideal Op amp has the … 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
DC-DC converters are also known as Choppers. Here we will have a look at the Step Up Chopper or Boost converter which increases the input DC voltage to a specified DC output voltage. A typical Boost converter is shown below. The input voltage source connects to an inductor. A solid-state switch is connected across the … Read more
The Physics of a Semiconductor There are some materials, which have neither good conductivity nor bad conductivity of electricity. They have a moderate range of electrical conductivity. The examples of such materials are germanium, silicon, carbon etc. As the conductivity of those materials lies between good conductors and insulators, and these materials are called semiconductors. … 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 Buck Boost Converter? The buck–boost converter is a type of DC-to-DC converter (also knownas a chopper) that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is used to “step up” the DC voltage, similar to a transformer for AC circuits. It is … Read more
Based on the behavior and properties of Superconductors, these are classified into two categories-(1) Type – I Superconductors: Low Temperature Superconductors.(2) Type – II Superconductors: High Temperature Superconductors.Type-I and Type-II superconductors differ slightly in their behavior and properties. The comparison of type-I and type – II superconductors is shown in the table below Type – … 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
