Air Compressors

As an end user, have you ever heard the message to put in the biggest VFD air compressor, and the system will always be reliable and efficient.  Why do an audit?  Just add up the compressors on site and put one VFD for that size or larger.  Why have the complexity of multiple compressors, storage, sequencing, etc?  Even better, put in two of them, one for the whole system, and one for back-up.  If you could wave a wand, wouldn’t that be what every system should look like?  Perfect peace and efficiency, with 100% confidence of reliability.
Nuclear power plants produce electricity for people, business and industry.  Electricity is produced in a similar fashion as fossil fuel (i.e., coal, oil, etc.) power plants, using steam to drive a turbines which spin an electrical generator, producing the electricity. 
Safety is the driving force in the determination of minimum recommended supply wire sizes for variable speed compressor packages.  With this in mind, all wire size recommendations should be based on meeting, or exceeding, the minimum requirements of the National Electrical Code (NEC).

A four thousand, five hundred and fifty pound (4550 lbs.) race car is running at 170 mph and facing wind resistance of 150 mph. The car then enters a curve creating a three-degree “yaw” (the change in angle from the direction the car is headed and the airstream).  The car struggles to maintain speed as the yaw changes and the dynamic downforce load on the car changes.  Suddenly, the driver-less car comes to a stop on the stainless-steel track...
