Determining Generator Loading
Determining Generator Loading
(OP)
We have a 750kW 480V generator here at our plant to provide emergency power to certain loads in the event of a power loss. I am trying to determine weather or not we have room on this generator to add additional loads which we have determined should be on emergency power.
I plan on adding up all of the loads from a theoretical standpoint, as well as take some power recordings of these loads in the field during normal operation.
What is the best way to determine how much a generator can be loaded? I have seen other threads that have referened free software from manufacturers for determining these values? What are typical factors or calculations that can be used from a theoretical standpoint with particular loads?

Standby generators are.
Prime power generators are not only continuously rated but allow a 10% overload, 1 hour out of 12 hours.

RE: Determining Generator Loading
Is your 10% overload (1 hour out of 12 hours) relates to the engine ekW or Generator kVA?
