GAS RATINGS DEFINITIONS

CAT GAS RATING DEFINITIONS:

Stand by Power These ratings are applicable for supplying continuous electrical power (at variable load) in the event of a util ity power failure. No overload is permitted on these ratings. Natural gas ratings have been established on natural gas with net calorific Low Heat Value (LHV) of approximately 35.6 MJ/m3 (905 Btu/ft3) and 80 methane number (MN).

Continuous Power Output avai lable without varying load for an unlimited time. Continuous power in accordance with IS08528, AS2789, and BS5514. Natural gas ratings have been established on natural gas with net ca lorific Low Heat Val u e (LHV) of approximately 35.6 MJ/m3 (905 Btu/ft3) and 80 methane number (MN).
