I see several Fluke meters that costs a fortune, such as:

Any other suggestions?


Power company for one. If they are running equipment like an air
compressor, the suppliers will do it for you. There are outfits that do
energy audits that will do it and also find ways to reduce load.

How big an outfit is this? 1000 A at 460V will run a lot of equipment.
We have 600A and run 14 molding machines, 1 150hp compressor, 1 75hp
compressor, 2 boilers, assorted pumps, cooling towers, lighting and more.

I've had 1 week monitoring and never paid anyone anything.
