In the dim past as a civil student doing some basic electrical, I seem to recall that there was something called "power factor correction" which presumably adjusts the collective PHIs to reduce their root mean squares. I guess this is not going to be relevant to light/medium duty...
On the one hand we know that not every piece of equipment will be going at the same time, on the other - what about start-up loads?
In a typical refrigeration plant (for fruit and vegetable cool store), what "overload" will a motor cause when starting up, and is it necessary to...
Thanks for the helpful response.
I think I get the general approach.
I guess lighting and heating doesn't have a power factor but motors do.
Sorry to be thick but:
But what is the difference between ph and fi and where do you find it (or them)?
What is an average default value for this...
Professor Harry J Hopkins Professor of Civil Engineering and Dean of the School of Engineering University of Canterbury, New Zealand, wrote a history (1970) titled A SPAN OF BRIDGES. With U of Canterbury a leading research school in earthquake engineering, I'm sure that EQ engineering will be...
As a non-electrical engineering manager I am looking for a starting point to learn how to estimate the electric power requirements for an industrial complex using refrigeration compressors/motors, battery charging for forklifts, general lighting, air conditioning system, general office use...
