Introduction In the modern era of industrial automation, Programmable Logic Controllers (PLCs) play a crucial role in ensuring smooth and efficient operations. These robust and versatile devices are widely used in manufacturing, assembly lines, and various automated processes. But what exactly is a PLC, and why is it so important? What is a PLC? PLC stands for Programmable Logic Controller. It is a digital computer that manages the electromechanical processes of an industrial environment. PLCs are used in automation and form part of a larger SCADA system. They can be programmed according to the operational requirement of the process. PLCs use a microprocessor to control equipment through a program that can be changed by the user. The program is often created using a ladder chart system and programming tools such as CX-Programmer. A Programmable Logic Controller (PLC) is an industrial digital computer designed to control various electromechanical processes. Unlike traditional co...
A nuclear power plant is a facility that generates electricity by using nuclear reactions, typically nuclear fission. The plant consists of a nuclear reactor , where uranium or plutonium atoms are split to release a large amount of energy in the form of heat. This heat is used to produce steam, which drives turbines connected to generators that produce electricity. Main Components of a Nuclear Power Plant Nuclear Reactor – Contains the fuel (usually uranium-235 or plutonium-239) and controls the nuclear chain reaction. Control Rods – Absorb excess neutrons to regulate the reaction and prevent overheating. Coolant System – Transfers heat away from the reactor (typically water or liquid sodium). Steam Generator – Converts heat into steam. Turbine & Generator – Steam drives turbines connected to an electricity generator. Condenser – Cools the steam back into water for reuse. Containment Structure – A reinforced concrete and steel structure that preve...
A capacitor is a two-terminal electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material known as a dielectric. The capacitance (C) of a capacitor is a measure of its ability to store electrical charge and is defined by the equation: CAPACITORS where: � C is the capacitance, � Q is the stored charge, and � V is the voltage across the capacitor. � V is the voltage across the capacitor. The unit of capacitance is the farad (F). One farad is equal to one coulomb of charge stored per volt of potential difference. Capacitors are widely used in electronic circuits for various purposes, including energy storage, filtering, coupling, and timing. They c...
