The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
We have a sister note to this (Robots - Interesting Video), in which I have posted some videos of interesting robots developed by commercial corporations...
If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
