Corona Discharge, also referred to as the Corona Effect, is an electrical discharge phenomenon that occurs when a conductor carrying high voltage ionizes the surrounding fluid, often air. The corona effect will occur in high-voltage systems unless sufficient care is taken to limit the strength of the surrounding electric field. It’s since corona discharge involves … Read more
A high-voltage transformer is a device that converts high-voltage AC power to low-voltage AC power or vice versa. High-voltage transformers are mainly used for testing electrical equipment and components under high voltage conditions in laboratories or factories. They can also be used for power transmission and distribution, as well as for special applications such as … Read more
Power transformers are essential equipment for transmitting and distributing electrical power in power systems. They are used to step up or step down the voltage level, improve the power quality, and isolate different parts of the network. Power transformers are also expensive and complex devices that require proper installation, testing, and maintenance to ensure their … Read more
Transformer oil is a vital component of power transformers and other oil-immersed electrical equipment. It serves as an insulator, a coolant, and a protection against corrosion and oxidation. Transformer oil also carries dissolved gases that can indicate the condition and performance of the transformer. To ensure the reliability and efficiency of the transformer, regular oil … Read more
What is DC Current? DC stands for Direct Current, although it is often called “DC Current”. DC current is defined as a unidirectional flow of electric charge. In DC current, the electrons move from an area of negative charge to an area of positive charge without changing direction. This is unlike alternating current (AC) circuits, … Read more
Electric Power Transmission Electric power transmission systems are the means of transmitting power from a generating source to various load centers (i.e. where the power is being used). Generating stations generate electrical power. These generating stations are not necessarily situated where the majority of the power is being consumed (i.e. the load center). Since distance … Read more
The flue gases produced due to the combustion of solid pulverized fuel in the furnace contain plenty of dust particles. When a chimney releases these flue gases in the atmosphere without filtering these dust particles, the atmosphere may get polluted. Hence, these dust particles need to be removed from the flue gases as much as … Read more
Electrostatic precipitators are ubiquitous nowadays in thermal power plants due to ever-increasing concern about environmental pollution. Electrostatic precipitator uses the high-intensity electric field to ionise the dust particles in the air stream and then the dust particles are collected by oppositely charged collectors (electrodes). The dust particles, once collected are removed from the collector plates … Read more
Electrostatic precipitators are mandatory nowadays in thermal power plants and other power plants where there is a discharge of flue gases. With ever increasing concern about environmental pollution and the need to reduce it, electrostatic precipitators have become a necessity. Electrostatic precipitator uses the high-intensity electric field to ionise the dust particles in the air … Read more
Electrostatic precipitators have become the norm now in industries. Due to strict regulation and ever-increasing air pollution, installing one in a thermal power plant or any other power plants where flue gases are released, have become a necessity. But whether electrostatic precipitators perform the function expected from them can be determined by measuring the efficiency … Read more
