[Beowulf] on powering off and its character

[H. Vidal, Jr.]

All,
 Just curious if anyone here among those well-informed about the nature
of electrical power might know about documented or canonical analysis
of AC power as it's being turned off......

 That is, is there existing and/or standard analysis or characterization of
typical AC power as power is removed? Does it ring, or spike, or otherwise
modulate in understood or at least studied ways?

 Will google it as well, one of our engineers tried GIYF but came up short.

Thanks.
