AFDD BREAKER: I explain How the Arc fault detection device AFDD breaker, AFCI circuit breaker prevents Arc fault short circuit electrical fire and the AFDD working principle.
The arc fault detection device (AFDD) also called arc fault circuit interrupter (AFCI) is a type of circuit breaker to protect from an arc fault. It senses the presence of an arc by measuring the high-frequency current signature of arc current in the circuit and disconnects the AC supply in case of an arc fault.
Then, the Generation of fire due to an arc fault type short circuit with a high impedance path is also explained in this video tutorial. Fire is also generated due to series arc fault Series and parallel arc fault, block diagram of AFDD, high-frequency current due to arc fault, arc fault current signature is explained.
Further, Siemens make Arc fault detection device AFDD circuit breaker with over voltage protection is shown. Electrical fire causes and how electrical fire start is also explained. In this video, I have shown a Siemens AFDD breaker also.
Further, how an electrical fire starts and the cause of the electrical fire are explained.

About the Site 🌐
This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥
Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube 📺
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟
Content and Users 🎵
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact 🤑
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
