STANDBY OR PRIME?

What is the meaning of standby and prime ratings? Standby power ratings for specific gen set models are determined under the following parameters: * peak cylinder pressure * exhaust temperature * smoke level * turbocharger speed (if applicable). It is further defined as the output available with varying load for the duration of the interrup- tion of the normal source of power. Ratings are based on fuel stop power in accordance with ISO 3046/1, AS 2789, DIN 6271 and BS 5514. The fuel stop is fixed for each engine model/configeration. It represents the maximum safe horsepower the engine model/configuration will be able to produce with without exceeding the limits set according to the parameters. Prime ratings are defined as the output available with a varying load for an unlimited time. It is set approximately 10 percent below the standby power ratings for each model/configuration. Are there any other ratings? A. Continuous rating ...

ELECTRICAL DESIGN OF INSTALLATION

The electrical design and planning of the on---site generation system is critical for proper system operation and reliability. This chapter covers installation design of the generator and related electrical systems, their interface with the facility, and topics regarding load and generator protection. The electrical installation of the generator set and its accessories must follow the Electrical Code in use by local inspection authorities. Electrical installation should be done by skilled, qualified, and experienced electricians/contractors. Electrical System Designs tend to vary considerably based on the needs, or primary functions of the power generation equipment in the application. A system design that is optimized for emergency service situations will generally not be the best fit for interruptible service and is definitely not the same type of system design as a prime power application. The one---line configuration differences are easy to see. For example, in prime applicat...

WHAT IS A GENERATOR SET?

From Wikipedia, the free encyclopedia (Redirected from Generator set ) NRC image of Modern Steam Turbine Generator. In electricity generation , an electrical generator is a device that converts mechanical energy to electrical energy . The reverse conversion of electrical energy into mechanical energy is done by a motor ; motors and generators have many similarities. A generator forces electric charges to move through an external electrical circuit , but it does not create electricity or charge, which is already present in the wire of its windings. It is somewhat analogous to a water pump, which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine , water falling through a turbine or waterwheel , an internal combustion engine , a wind turbine , a hand crank , compressed air or any other source of mechanical energy. Historical developments Before the connection between magnetis...
