If I have a customer who provides me with their peak kW demand (say, 1000 kW) and wants to know if it is sufficient for them to downgrade from a 2500 kVA unit to a 2250 kVA unit.
Is this determination made by simply using the formula kVA=PF/kW? I don't have a power factor from them - yet. Also, is it the Transformer's PF I use or is it the load's power factor? Is there any guidance/code/recommendation for how much "room" should be left based on peak demand?
