The 400kw diesel gensets are housed in a soundproof enclosure, which can reduce the noise produced by the generator effectively and protect the genset from the elements such as rain and snow. The noise level is 75 dB at 7 meters. These silent diesel generators can be installed both indoors and outdoors. The genets are equipped with a 750L bottom base fuel tank, which can ensure that the generator has sufficient fuel supply to generate electricity for extended periods of time.
Before buying a diesel generator, you need to consider several factors to choose the one that can best fits your needs. It’s necessary to have a basic understanding of the prime power rating, standby power rating and continuous power rating.
Prime power ratings is applicable for supplying electric power in lieu of commercially purchased power. Prime power applications must be in the form of the following two categories:
Prime power is available for unlimited number of hours per year in a variable load application. Variable load should not exceed a 70% average of the prime power rating during any operating period of 250 hours.
The total operating time at 100% prime power shall not exceed 500 hours per year.
A 10% overload capability is available for a period of 1 hours within a 12 hour period of operation. Total operating time at the 10% overload power shall not exceed 25 hours per year.
Prime power is available for a limited number of hours in a non-variable load application. It is intended for use in situations where power outages are contacted, such as in utility power curtaiment. Engine may be operated in parallel to the public utility up to 750 hours per year at power levels never to exceed the prime power rating. The customer should be aware, however, the life of any engine will be reduced by this constant high load operation. Any operation exceeding 750 hours per year at the prime power rating should use the continuous power rating.
Standby power rating is applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. Under no condition is an engine allowed to operate in parallel with the public utility at the standby power rating.
This rating should be applied where reliable utility power is available. A standby rated engine should be sized for a maximum of an 80% average load factor and 200 hours of operation per year. This includes less than 25 hours per year at the standby power rating. Standby ratings should never be applied except in true emergency power outages. Negotiated power outages contracted with a utility company are not considered as emergency.
Continuous power rating is applicable for supplying utility power at a constant 100% load for an unlimited number of hours per year. No over load capability is available for this rating. This rating is approximately 70% of the prime rating.
