AAARRRGHH, I almost flunked out of engineering school on all that Delta/Wye and conversion stuff ! Curiously, I sailed through the 1st two quarters where DC circuits & Ohm's law was taught. Hey, I had my ham license....I KNEW all this stuff already...HAH. 3Ø AC theory just about did me in.
To this day, I don't believe I have EVER had the need for a Laplace transform though. 73, Charlie k3ICH -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Phil Kane Sent: Sunday, May 19, 2019 2:14 PM To: [email protected] Subject: Re: [Elecraft] KPA1500 AC Mains wire colours On 5/19/2019 6:04 AM, hawley, charles j jr wrote: > BTW, I think if instead of saying "phases", it would be less confusing > to say two "legs" plus neutral for the single phase 240 vac coming > into the house. As an electrical engineer whose major was "power" (back when it was actually taught) I would agree wholeheartedly. The "2 hot plus neutral" is most often a single phase of a three-phase delta 240V secondary with tapped center as "neutral". It could not be two phases of a wye because the voltage from phase to phase would then be 208V for 120V phase-to-neutral. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
