Great video and very well explained in a short time, not making it boring at all. The only thing I have a comment and felt there was a mistake was the current equations shown in the figure at 3:21. The thing you have done is that ground fault current is divided in each tower, and flows up to be added in each overhead earthwire (OHEW) span, and the final I = I1+I2+I3. This means the OHEW span farthest from the fault span has the maximum fault current. But its just opposite of that. IEEE 367 states that "Near the fault, overhead ground wire may carry up to 80% of the fault current, which is then gradually dissipated into the earth at each successive tower or pole." So actually, the earthwire fault current gets divided into the earth in every tower and ground portion of the fault current gets added up as they flow to the remote substation. The first overhead earth wire section will bear the most current and will decrease down the transmission line section far from the fault. This is very well explained in the book "Power System Modelling and Fault Analysis, Theory and Practice" by Prof. Dr. Nasser Tleis, chapter 11th for the second edition.

OHE of the outgoing line should separated from power station line gantry by using a disc insulator, is that right?

Thank you sir.. I have two questions.. 1. Why all fault current return from transformer neutral 2. If transformer is delta-delta then how fault current behave

Sir, I have one question, Why is plant grounding not based on step and touch voltage calculations? Why just substations/switchyards(IEEE-80)?

Excellent Video but Current I and I4 distributed in ground grid instead flow in X'Mer netural as the current flow in low resistive path i.e ground grid may right or wrong sir

Sir which voltage is more dangerous touch or step?
@electricaltechnologyandind5335
4 жыл бұрын
Touch voltage. Because that is difficult to maintain within the limit. I should say touch voltage creates more nuisance than step voltage for designer. But if you consider hazard both are dangerous.

Our 15/110 KV step up transformer input cables screen shield is connected to main earthing system . Day before we have measured by current multi meter and found that 20 Amp current flowing from earthing cable . i know for the induction some amount of the current should flow from earthing system but i don`t know how much is acceptable . If you know any legal information please let me know.Thanks for advance
