3:20 Good that you are trying to explain in layman's words.. To clarify the high concentration of electric field in the void, we can use the following equation for a homogeneous field: E-field_airvoid/E-field_solid= ε_solid/ε_airvoid Where, ε_solid> ε_airvoid
on Causes of PD: i don't know how you would categorize this, but, a real cause can be an external lightning strike. a cause can be combinations of causes working at the same time. an example would be an insulation rated at 180kV has a minor defect at one spot the can protect only 160kV. at time of first energization all is well, but over time the insulation ages enough to drop its protection level by 15.001kV. the minor defect will now protect at 144.999kV. now that particular spot will have the conditions of a cause of PD. this would a combination of defect and aging that each alone would be a cause.
Request you to please start a dedicated playlist on Practical Power Systems Protection including Feeder, Motor, Transformer, Generator and Transmission lines.
With carbon particulates in the air, if this is allowed to coat insulators over time, the very high voltage will use it as a path to short circuit and can cause a tracking path and heat damage to the insulator. Gaz UK
How may Partial Discharge occur and what would be its location in GIS Switchgear? Because as we know there is a window provided to see if PD takes place or not in GIS Switchgear. Please feel free to correct me Sir my understanding is wrong...Thank You so much for detailed information. It is very useful and important to understand. Thanks sir!!
Sir , can you make a dedicated vodeo on voltage fluctuation issue in distribution network because of high PV penetration to the system.At least give me a reply sir.
Your amazing ❤️.. your explanation 🔥... Recently iam taken a free course on circuit breaker antipumping ... I financial some prblem is there but idhi I will try to take paid courses also soon just because of your information regarding that topic is literally awesome thanks a lot .. and one more thing is that if anyone is there and saying that electrical engineering is tough... But not with gaurav sir teaching 💯
Explained with practical examples are very helpfull to understand the topic 🥰😍❤️
Glad it was helpful!
❤❤❤❤❤
Very Helpful.
I was looking for PD since long time. Now my curiosity end here :)
Thank you, Gaurav.
Glad it was helpful!
Really superb sir.Very interesting. I learn new things about partial discharge.Thank u sir.

appreciated for the video! good job!
PD Types. Loved watching your videos.
PD types , great explanation
PD types. Thank you!
Crystal clear the concept 🥳😊👍
PD types.
How can we identify and rectify it?
Can you do a video on hotspots and thermal scanning methodology?
Thank you!
PD types.
Also if possible please provide dedicated playlist regarding substation automation such as working of SCADA, PLCC etc...

Excellent explanation, thank you sir.
I have a presentation at my office and partial discharge topic is related to my work thats y...what is the process to get details
Superb video! Plz make video on the apparatus decting PD
Thanks!
Thank you Sir. PD Types
Thanks for the feedback!!
Nice video sure more informative make video with bandwidth of pd
Thanks for the feedback
Good Explanation 👌🏼
Pd types
Thank you !
Thanks for the feedback
Thank for the rich and beautiful content,
Is it possible to share with us more resources about modelling and simulation of partial discharge
I will try my best!
@@GauravJ thanks a lot it will be very appreciated
Wish you also touched upon early detection of PD like using thermal imaging.
Very nice
Need hv cable testing method topic
Sir I want power point file for partial discharge topic can u plz share
Request you to please start a dedicated playlist on Practical Power Systems Protection including Feeder, Motor, Transformer, Generator and Transmission lines.
Sure. I will try
@@GauravJ Thank you 🙏
Thanks. Please explain how to detect PD for each type of equipment.
Sure. Will try!
Thanks sir.... Pd type
Pls make video What are the difference between insulation resistance test vs HV Test vs PD test and why required to do in switchgear
Thanks for all.
Please make a video on VLF testing of cables
Need some videos on protection relays

Yes!
Provide videos for pd types and pd detection methods
Thanks for the feedback.

Please do PD Types
Thanks sir
Most welcome!!
Thanks
PD Types 🙏
Pd types pls.
PD Types please Sir
PD testing please put videos
why am here Mechanical engineer . Seeing your videos
Pd type and bus raiser
Testing to find PD.
👍👍
Plz share detail part.
Thanks for the feedback!
