Congratulations ! I just watched this Webinar and it was the best instructions compilation to learn about EMTP-RV use for transient studies, that are nos statistical. It was really helpfull. Thank you very much !
Splendid job, expect more similar videos in which they build the model from ground up so that users can understand what is happening and how it is happening
Hello friend, I have one question, I hope you could solve this question mark. Why does in minute 2:55, you show a electrical diagram with the CVT before the surge arresters..?? I think that If I put the CVTs first than the SA, the CVTs could sense the entire lightning stroke..!! isn't it..?? I hope you could solve this question..!!

The location of the CVT is entirely up to the station designer, perhaps at this case, they are at the bus entrance.The SA might be put in different places (some in cascade configuration even, observe at minute 1:38:24 ), but they exist specially to protect the TRX. Then, the SA are usually close to the TRX, observe that he includes the inductance between the SA and the TRX, that value is of importance for the insulation coordination of the TRX.
[UPDATE] Hello everyone, Something slipped up in the video, sorry about that, indeed at 1:32:44 the correct information is: "The unit should be micro Henries .The rule of dumb is 1uH / m." Enjoy the video !

Hi.. variable "d" is height of the arrester in meter.. In the sub-circuit model, it is used as d=0.56 . In which unit was it used? km ?

How to load arrester details?

Enjoy the video !
1:03:44 shouldn't it be the SQRT() DIVIDED by u[2] ?
u[2]=1/R0. Admittance vs resistance
@@kettch42 Right, forgot that u[2] was actually the admittance and not R0. Thanks!
Is there a way to get the files in this webinar? Primarily, I am looking for the script used at the end.
I should add-- I found the files on the EMTP exchange platform, but the .dwj file is not there. Thanks.
@@kettch42 Please send me an email, I will share with you. I tough the were on the exchange platform as well.
