The history of LEDs can be unknown to you. But we all know that What is LED? The LED light is the latest technology for the energy-efficient lighting system. Because, before LED we used CFL, Halogen stands and Incandescent bulb and those are much energy consumes lighting technology. LED stands for ‘Light Emitting Diode’ and it is a semiconductor device…
What is the Difference in AC current and DC current and Why do we use Alternating Current for mains electricity? Ok, let’s talk about this most common topic today. And our topic is AC (Alternating Current) and DC (Direct Current). It does not matter what you do in real life but you have Electricity at your home. That’s means we…
If this is the first time learning about Fuse for you then I request you to read my previous post about Fuse Operation Principle with Design. You will get some ideas to understand this article. In this article, I will discuss Fuse Properties with the Rating Principle. Fuse Voltage Ratings: The rated voltage of a fuse is the nominal voltage…
Fuse is the most common protection system for an electrical circuit system. It does not matter how big or small is the circuit system it must go through a physical fuse protection system. Fuse Operation With Design: Generally, a fuse consists of a replaceable part (Fuse-link) and a fuse holder. You may already see several types of fuse during work….
I already posted a few articles about the generator, its types and some operation principle with stapes. In this post, I will discuss the AVR (Automatic Voltage Regulator) system and try to learn how it works. Some small type generators have an inherent ability to produce reasonably constant voltage if the load varies sometimes automatic voltage control is required in…
Switchgear is responsible to connect and disconnect the electric power supplies and systems. Switchgear is a general term which uses to covers the switching device and its various combinations with some associated control, measuring all parameter, protective and regulating equipment, together with accessories, enclosures and supporting structures. Switchgear mainly applied in electrical circuits and systems from low voltage like domestic…
By the word Generator, we can understand that, it’s generate something. Electrical Engineering Generator mainly uses for Electricity Generation. But Generator cannot generate electricity by itself. It needs a prime mover that helps the generator to rotate and by this rotation inside the generator creates magnetic flux and creates electricity. Around the world, there is a need for generators for…
Industrial Automation makes our machine operation very first with accuracy. We can control our machines in various ways to get our optimum output and production. Using Programmable Logic Controller (PLC) is one of the world’s most popular automation systems. In my last post, I discussed ‘What is Programmable Logic Controller (PLC) With Application?’ So I request you before you proceed…
Programmable Logic Controller (PLC), used for controlling machine and its equipment. By the name of PLC, we can separate its operation basic three ways. The first part is programming with some logic in the second and third is controlling. So make a program with logic and PLC will control the machine by your logic. PLC is a kind of computer…
Underground Residential Distribution (URD) is a common power distribution system for a modern city in this world. If you are visiting some of the greatest city you may not find any overhead distribution cable. Generally, a classic underground residential distribution circuit system is an underground circuit in a loop type arrangement that fed at each end from an overhead circuit….
