Diesel Ratings
Rating Definitions:
Standby Power Rating
— Output available with varying load for
the duration of the interruption of the normal source power.
Average power output is 70% of the standby power rating.Typical
operation is 200 hours per year, with maximum expected usage
of 500 hours per year.
Prime Power Rating
— Output available with varying load for an
unlimited time. Average power output is 70% of the prime power
rating.Typical peak demand is 100% of prime rated ekW with 10%
overload capability for emergency use for a maximum of 1 hour
in 12. Overload operation cannot exceed 25 hours per year.
Continuous Power Rating
— Output available with non-varying
load for an unlimited time. Average power output is 70-100% of
the continuous power rating. Typical peak demand is 100% of
continuous rated ekW for 100% of operating hours.
