Sorry to post a second time but, a great majority of our time as Electricians over here in New Zealand, is spent doing Power Quality measurements.
Whether it be Voltage/Current or Maximum Demand metering.
What we look to do for our customers, is to minimise thier kVA supplied vs kVA used.
Coming from a PoCo background, this is the biggest thing.
Power Factor is the biggest killing factor Of Industrial Power systems.
If your Plant has an over-all PF of 0.75 lagging, you are under using your conductors by 25%.
Motors are the biggest killers of power factor, having a reactive component to thier current.
I would look to correct to 0.95 or Unity.
