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!
can you show us a TWACS outgoing modulation transformer and tell us about it? i just posted a video of my smart meter making noise. i had 5 guys over here and they changed the twacs meter for an old school RF 450MHz meter and so far i'm not hearing that silly buzz anymore. it was making a bunch of electronic devices in my house hum for about 7 seconds.
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!
