Good work Sahil, especially helpful when you’ve been away from the core or been to the different sector for quite some years. Waiting your videos on SC and its monitoring.
Can you have a return path from the ground on the Moon, or Mars? It is a return path depending on soil resistivity, isn't it? Just a thought! (Instead of Earthing, you will be Mooning or Marsing!) Great lectures like always keep up the great work!
Thanks a lot. In case the source is on Moon/Mars and is feeding a load at the earth, then the return path will be the atmosphere as the current flows closed path. However, in this case, the current will be negligible, thus making it a high impedance fault. Current will do back to its source through the least resistance path, which could be less resistive soil in case it is available on its way back to the source.
Very useful. One feedback, your video assumes that the power supply is grounded. In Railway signalling, supplies are sometimes floating so grounding is not needed at the equipment side. Please check IT type power systems.
Many thanks... Very true... As it was the first video so prepared more generalised one... Will discuss separately in a video about different types of earthing system... TT, TN-S, TN-C, IT, TN-C-S as per IEC 60364 series...
Faraday cage is a solid steel box/cage preferably without any penetrations. Steel having high permeability is able to absorb high freq fields. Thus, protecting the circuit inside from external EM disturbances. As steel has higher conductivity compared to human body, the electric current will flow through it. This principle was used by Sir Tesla...

excellant...
Great lecture. Your way of explaining is quite easy for attendee. Thank you
Thanks
Very useful information elegantly presented and easy to understand even for people from non electricidal background.
Many thanks
Good video!!. Not only useful for electrical engineers but also for Non-technical people to understand the Electrical safety
Many thanks...
Nice Initiative, Sharing Knowledge
Many thanks sir...
Very easy to understand.. Thanks for sharing your knowledge and experience .. 👌👍
Many thanks...
Well-explained, simple and easy to understand.
Many thanks Dr. Palak... I have gone through your posts on LinkedIn.... They are amazing...
Sahil the way u explained it was super easy to understand... keep posting such videos...
Many thanks Upma...
easy illustration of basic knowledge
Very nice sir ji🙏🙏🏼🙏🏼
Good
Many thanks
👏👏👌👌
Very nice sir ji🙏🙏🙏🙏
Many thanks...

@@railwayengineeringinsights6463 I guess it's the same theory, it's universal! Ground is a return path no matter what planet you are on!

Nice lecture to begin earthing and bonding playlist. Is this concept related to how Faraday cage is designed?
Many thanks...not exactly...Faraday cage will a part of EMC series... Which is used to achieve immunity against radiated EM waves...
@@railwayengineeringinsights6463 how did Tesla walk in an electrified steel cage? Was is a Faraday cage?

Please put these courses on LinkedIn learning.
Surely will do... Many thanks for your suggestion...
Current part was very helpful sir. Value of two standards are somewhat mismatching. Should we take IEEE80 as final word?
It depends upon the contractual requirement which standard needs to be adopted. There are also other standards but which to follow is up to client.
