In this video I explain the summation of sine waves with a phase offset, using oscilloscope and phasor-scope. The Phase MS Excel calculator can be found here: www.merlijnvanveen.nl/en/calc...
Are these numbers only true when the sine waves combined are 1 decibel? If the sine waves are 10 decibels do you get 50, 30, -60 decibels or are two 10 decibel sinewaves combined in pefect phase to become 16 decibels?
Hi Merlin! In about 13 minuts you talk about L1, L2 and L3 phases of an AC generator. In this case the circuit is a summing circuit or an push pull circuit? Thank you!
I'm curious why two 120V legs of 208V 3 phase system, separated by 120º, sum to 208V instead of 120V as this calculator indicates? Anyone know why that is?
Excellent question! Sound pressure is about summation. Whereas three‑phase electric power considers the - difference - between phases, i.e., subtraction. I posted an illustration here: facebook.com/merlijn.vanveen/posts/1028349245335764
