Hi Scott and the regulars here. I have a question that I hope that you guys can help me answer. I have done these sorts of calcs a million times before, but owing to lack of practice in the last few years, I've forgotten how on earth they're done. OK, here we go: A given 3 phase Star-connected installation, has the following Phase currents:
R Phase= 30A
Y Phase= 25A
B Phase= 40A
Having this information, how then is the current likely to be carried by the Neutral calculated?. Thanks in advance, Mike Trump.
‘A tensor may be defined at a …collection of isolated points of space (or space-time), or it may be defined over a continuum of points.’
Now, maybe that’s sort of like explaining nth-dimensional systems. The simplest shadow of a 2-dimensional plane is a 1-dimensional line. The simplest shadow of a 3-dimension cube is a 2-dimension plane. [The simplest shadow of a 1-dimension line is a “zero-dimension” point.]
Outside of the human realm, the simplest shadow of a 4-dimensional “object” is a 3-dimensional form called a tesseract—which we view in 3 dimesions to be (roughly) a set of nested cubes. We cannot perceive a 4-dimension object—only its 3-dimension shadow.
Will someday be useful for polychoroniodic tetrasesquiphase zeptojoule power analysis..}
