Typical peak demand n/a n/a 100% of prime rated ekW with 10% overload capability for emergency use for a maximum of 1 hour in 12. The generator set cannot be operated at overload for more than 25 hours per year. 100% of continuous rated ekW for 100% of operating hours.
Typical application Building service standby Standby Industrial, pumping, construction, rental generator set, or cogeneration Base load, utility, or cogeneration
(1) Power is available for the duration of an emergency outage.
(2) The typical load factor is the sum of the loads a generator set experiences while it is running under load divided by the number of hours the generator set operates under those loads. Extended idling time does not enter into the calculation for the load factor. Time that the generator set is not operating does not enter into the calculation for the load factor.Operating units above these rating definitions results in a shorter life before an overhaul.
