See Wikipedia’s guide to writing better articles for suggestions. A Cummins diesel generator of 150kVA temporarily parked in a tourist resort in Egypt. A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as emergency backup at a sewage treatment substation in Atlanta, United States. This is a specific case of engine-generator. Diesel generating sets are used in places without connection to a power grid, or as emergency power-supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support and export to the power grid. Proper sizing of diesel generators is critical to avoid low-load or a shortage of power. Sizing is complicated by the characteristics of modern electronics, specifically non-linear loads.
Diesel generator on an oil tanker. Ships often also employ diesel generators, sometimes not only to provide auxiliary power for lights, fans, winches etc. With electric propulsion the generators can be placed in a convenient position, to allow more cargo to be carried. Most of the larger generator set manufacturers offer software that will perform the complicated sizing calculations by simply inputting site conditions and connected electrical load characteristics. One or more diesel generators operating without a connection to an electrical grid are referred to as operating in island mode.
Operating generators in parallel provides the advantage of redundancy, and can provide better efficiency at partial loads. The plant brings generator sets online and takes them off line depending on the demands of the system at a given time. Generators can be electrically connected together through the process of synchronization. Synchronization involves matching voltage, frequency and phase before connecting the generator to the system. Load can be shared among parallel running generators through load sharing. Load sharing can be achieved by using droop speed control controlled by the frequency at the generator, while it constantly adjusts the engine fuel control to shift load to and from the remaining power sources.

Conductors of a three, packaging Details: Carefully and securely packed in Carton Box. Sizing is based on site conditions and the type of appliances – such motors are applied in industry for many applications.
