Frequently Asked Questions

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.

  1. Supporting main utility grids

    In addition to their well known role as power supplies during power failures, diesel generator sets also routinely support main power grids worldwide in two distinct ways.These diesels generator can in some cases be up and running in parallel as quickly as two minutes, with no impact on the site (the office or factory need not shut down).

  2. Cost of generating electricity

    Fuel consumption is the major portion of diesel plant owning and operating cost for power applications, whereas capital cost is the primary concern for backup generators. Specific consumption varies, but a modern diesel plant will at its near-optimal 65-70% loading, generate 3 kWh per litre.

  3. Generator sizing and rating

    Generators must provide the anticipated power required reliably and without damage and this is achieved by the manufacturer giving one or more ratings to a specific generator set model. A specific model of a generator operated as a standby generator may only need to operate for a few hours per year. Manufacturers give each set a rating based on internationally agreed definitions. These standard rating definitions are designed to allow correct machine selection and valid comparisons between manufacturers to prevent them from misstating the performance of their machines, and to guide designers. Sizing is based on site conditions and the type of appliances, equipment and devices that will be powered by the generator set.

  4. Installation of Gen-Sets

    Manufacturers provide detailed installation guidelines to ensure correct functioning, reliability and low maintenance costs. There are a range of different styles of generators for camping, RV’s standby power, and portable commercial applications. When purchasing a generator online you must ensure that the product comes with installation guidelines and that ts stipulated within the product description.

  5. When Engine damage

    Diesel engines can suffer damage as a result of misapplication or misuse – namely internal glazing. Running an engine under low loads causes low cylinder pressures and consequent poor piston ring sealing since this relies on the gas pressure to force them against the oil film on the bores to form the seal. Low cylinder pressures causes poor combustion and resultant low combustion pressures and temperatures. The situation can be prevented by carefully selecting the generator set in accordance with manufacturers printed guidelines.
