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...
ELECTRICITY : is an invisible force that can produce heat ,light , motion etc and many other physical effects the electricity energy is available in two forms (d.c) & (a.c) (D.C) means direct current AND (A.C)means alternating current DIRECT CURRENT (D.C) the direct current is that current which do not change direction it always flows in one direction from positive terminal to negative terminal of the source the magnitude of the direct current may have or not have a constant value and thus direct current has constant magnitude with time its purest form of direct current DIRECT CURRENT WAVE ALTERNATING CURRENT (A.C) the alternating current or voltage which changes its magnitude and direction with time regularly is known as alternating current an alternating current can also be defined as that which changes its magnitude in one direction from zero and then going through similar variation but in opposite direction ...
