Generator Loadbanking

Generator Loadbanking

Generator Loadbanking

(OP)
Nfpa 110 (standby generators states you must meet 30% of your rated generator load
every month. If not you must perform a load bank ,and the requirement is,
25% for one half hour 50% for next half hour and 75% for the last hour.(KW name plate)
The vender we use uses a resistive load bank. The question I have is would it be calculated with a .1 power factor as apposed to a .8 power factor?


RE: Generator Loadbanking

.1 power factor? How do you get that out of resistive load bank?

Sorry 1.0 pf

RE: Generator Loadbanking

Load is measured in Watts (or kW etc.)
The reactive component does not present any loading on the prime mover.
Use generator kW rating and load bank kW loading.

RE: Generator Loadbanking

resistive load banks are unity PF so you need to calculate at 1.

Thank you all for your input.
My suspicions are correct,
I am only a master electrician
and just needed to verify with
others, thank you all.
