Thank you for the very informative tour. Showed it to my current Level 3 Electrical Apprenticeship class in BC Canada. Students saw a number of items that were in their binders and you were able to add substance with your explanations. They all agreed, well done Jerred.
Love the video, just subscribed. Love the high quality, it may look even less shaky if you film and upload in 4K 60 fps (frames per second). You can go into your phone’s camera settings and crank it up there. Again, great video!
Good question. In order to determine direction of current flow, you actually need two "sensors". A CT will produce a secondary current based on primary current and the CT ratio. A PT (line pot, bus pot, etc) produces a secondary voltage based on the primary voltage of the line or bus. Potentials are used as the reference and the direction of the current is based on its phase angle as compared to the voltage angle. This is very important as this is how billing meters and directional-based protection elements are governed.
Station DC. Most important thing that the DC is used for is operating the breaker trip and close coils. It is used for many other things as well, but tripping breakers is the most important thing.
10/4, I understand, I’m a maintenance foreman @ a underground mines, we have a similar device called CTD capacitor trip device, it’s a charged capacitor that uses a shunt trip coil to trip the breaker if there is a line fault which would cause the control power to be to low to trip it, thanks much for the video, I’ve always been amazed by high voltage, but it must be respected!
Really enjoyed this video. Very informative, thanks for making it.

Thanks for commenting! I'm glad your class could get something out of it!

This is great. Thank you! Post more videos when you get a chance. This was very informative
Love the tour. Learnt a lot. Thanks!
Great walkthrough! Thank you.
Love the video of the substation
Very interesting, I’m a first year apprentice and this video was very helpful as I find high voltage fascinating 👍
Glad the video was useful for you!

Jerred, I was not that bad. It was great. Thanks for posting the video. It will be useful to show a 66-12kV substation
Great job!
How does a sensor (or what type of sensor) detects the direction of current flow? Thank you!

Do you have a switching operations manual
What are the batteries for?
