Awesome! Great explanation.
Glad it was helpful!
Wow, fantastic explanation in such a short interval!
Glad you liked it!
Hey, I've watched your stuff on Udemy
I hope you found it useful!! steve
So before I buy your course, what about split factor? Is there a reason why you're assuming all the fault current returns via the earth grid at the substation? Thanks
Hi, We cover the current division factor in the course. Regards Steve
sir can u explain by video what happen if we use different class for overhead line..substation A using CT class X..but another remote end substation using CT class 5P20..what happen if fault occured..??
Hi, The 5P20 CT’s will be less accurate than the class X CT’s, this will become clear if you have a high current fault and the relays at the two ends will show different current levels, this difference may in incorrectly identify a fault on the line being protected. Regards Steve
@@Electricalsteve tq steve..👍
thanks alot 👩🎓👍❤🙋♀️
Wow 😳.. thank you so much
Welcome!
wow!! very very nice not teacher but you are doctor congratulation.
Thank you! 😃
🙋♂️💟💟🙋♀️👍
How can i buy all your protection and control video, at once, not part by part
Hi Tom, unfortunately that’s not an option on Udemy, you need to pay for each course separately. Regards Steve
Wouldn't the sheath be energized up to the receiving station
Hi Kevin, at several cable joints along the route we ground the sheath with a non linear resistor to keep the induced voltage down to an acceptable level. steve
Thank you Sir. You illustrations and explanations have helped me understand so many concepts. Appreciate it!
You're very welcome!
Awesome as usual
thanks!!
Good day Sir, can you give me some advise what books should i read to understand the field of power system protection. Thank you Sir Have a nice day
Hi Nino, I would suggest looking at the free UA-cam videos to give you an introduction, if your interested do the full Udemy courses to give you in depth knowledge. Regards Steve
Thank u ❤❤❤
Always welcome
Must watch
Thanks for the feedback!!

Great Information 👍
Glad it was helpful!
if for longer period the step voltage applied is less....then how person is in more dangerous position in less voltage......pl guide
In RYB star connection...if r phase is grounded...then other phase voltage will be equal line voltage.....is it correct?
Stephen's knowledge, delivery, and production quality are superb.
Much appreciated!
Hi Stephen, thank you for making the videos, is there a discount code for the online courses? I’m looking to purchase them in bulk if possible.
Awesome video!
Hello, any recommendations for an application to calculate the NH Fuse Melting Time?
Useful tutorial
Thanks a lot
I appreciate your walkthrough Stephen. I am studying for the PE (power) exam and this helped me tremendously. One thing I want to add is the formula you referenced is only applicable for grids with depths between 0.25 - 2.5m. However, the concepts remain the same and all formulas are provided by NCEES. Thank you again!
Thanks for the formula and explanation. Will the shape of the earth system conductor play a roll in the Value of Rg. A rectangular bar will have a larger circumference and more contact area with ground than a round conductor.

I wonder if it is an ANSI vs. IEC thing, but normally in ANSI we would have the CT's on the opposite side of the breakers, as shown. This was the breakers at each end are protected by the differential protection. In the scheme as shown, either breaker could fail and would need some other protection scheme to sense the fault.
Hi, it’s not really an ANSI/IEC conflict, most utilities only have one set of current transformers on the line side now to save money and use other protection functions to detect a fault in between the CT / circuit breaker ( short stub fault ). Steve
@@Electricalsteve Maybe it's a regional thing. I commission HV substations, including the apparatus outside and the protection systems inside the control house. Our standard new dead tank circuit breakers have a total of 18 CT's per breaker. For a line breaker the bus side CT's are used for primary and secondary line protection and the line side CT's are for primary / secondary bus protection. Having the diff CT's on line side ensures the breaker itself is covered in the diff scheme. In a ring or breaker and a half scheme, it may be a little different. One last set of CT's may be used for breaker failure protection and the last may be for revenue metering. We have older installations that don't have as many CT's (we call CT deficient), but that can cause issues down the line - shared CT circuits and someone does maintenance test with doble -plugs paddle in while connected to doble and shorts diff relay and a nuisance trip. I believe for the relative low cost of additional CT's on a dead tank, many utilities choose to have the extra CT's for flexibility and ease of wiring and maintenance. Digital relays also help quite a bit if sharing CT's as the polarity can be adjusted internally in the relay for compensate.
Superb trick
thanks!!
thank you
Welcome!
Man, you are good! Please understand that, you are legend. Just the way you start from the very bottom and cover everything up to the top is the only way I can understand.
Am glad you found them useful!!
sir, do you know how to size cable for transformer neutral earthing? my transformer is delta y. 3MVA 33KV / 415 V.. I hope you can help me sir
Hi Stephen please can you send me a 9.99 voucher code. Thanks
I NEED THE VOUCHER, SIR,
Hi Muhammad , To use the attached coupon code go to the Udemy website, register, search for the course / my name ( Stephen Brooks ) then select the course you want and enter the $9.99 voucher code UHEK1001 Regards steve
Does the course cover DC busbar sizing?
Great topic
What if the generator is impedance grounded like neutral point is having a NGT?
Wave cycles that occur every second, not every minute.
Thank you for this. I was questioning myself on this video.
Hi Sir. Just a quick question. The busbar rating for the current is multiplied by 3. But why is the voltage not mulplied by 3 also?
Hi, The system voltage is kept constant regardless of the power output of the transformers or the size of the loads. If the voltage is constant then the only thing that can change as the power magnitude changes is the current and it does, when the power drawn by the load increases the current increases. Regards Steve
Wow!! You are indeed a legend in the power sector and a great teacher too.
Thanks for the kind words Kenneth, glad you found the course useful!! Steve
Informative 👍
Thanks 🙂
Excellent explanation
Glad you liked it
i need discount
Hi Zaid Go to the Udemy website, search for courses under my name ( Stephen brooks ) & use the voucher code IGST1001 to get them for $9.99, vouchers expire in 5 days. Regards Stephen Brooks
Power cables have a more bending radius then control cables
Hi, Every cable has its own unique bending radius defined by the manufacturer. steve
Hi Stephen, could you please write me your email address? I need it in relation to the Udemy voucher. Thank you in advance.

@@Electricalsteve Thank you, purchased.
Sir, what about the electrical room in which main panel (floor mounted) of the building are installed. half meter distance is enough from the wall for future maintenacne?
Hi Osman, I recommend 1.5 meters in the video, but the actual distance will depend on your circumstances….as a minimum you need to be able to walk between the opened panel door and wall…Steve
