  • Hey guys, I was looking for green roof instructions. I have to say this video is confusing, ya'll say "vector or ground fault detection", those are not related concepts. The "electromagnetic potential difference" is simply "voltage". Oh, yeah, ya'll talk fast for us southeners. I can hardly keep up with the explanation. Also I don't think using acronyms is ever a good idea. EFVM is fancy talk for voltage tracing. These guys trace the flow of water with electricity. and measure abnormal currents.
