    This might be a loaded question. What is the importance of electrical phasing and calculating phase angles.

    Thanks

    'vague' is the word I'd use rather than 'loaded'. Depending on your applicaton, phasing can mean nothing, or can be everything. In what context are you thinking?

    I agree, but it's a pretty good pun in this context! :p "loaded" question

    In the AC electrical world, phasing is everything. Actually, phasing infers differences in time. When you intend to operate two different sources of electrical energy in tandem or parallel, they must be near the same amplitude, and the same in the time domain. That is to say, when source A is at the positive peak of its cycle so then must source B. (It can be very dangerous or even deadly in some circumstances if not)
    This situation occurs every day in power systems around the world. Generators are added into the power system often and to do so safely, they must be "in phase" or matched time wise to allow successful connection to "the grid".
    So, knowing the accurate state of phase or timing is very necessary.
