Diesel generators are devices that combine a diesel engine and a generator to produce electrical energy. These devices are used as a power source in case of interruptions in the electrical network or in cases where on-site electricity generation is required.
The advantages of diesel generators include low fuel consumption, high efficiency, long life, easy maintenance and durability. In addition, they generally run quieter and produce fewer emissions than gasoline generators.
Diesel generators can be used with automatic switchgears that can be opened and closed automatically. These devices automatically activate the generator when there is a power outage and automatically shut down the generator when the power outage is over, thus saving energy.
