When buying a generator

When buying a generator

  • Before purchasing a generator, ask the experts to measure the load power and determine the total power required in kVA.
  • Ensure that all installation and start-up works are performed by a qualified technical person.
  • Decide about using the generator as a Standby, Prime, or Continuous power source.
  • Be aware of selecting a suitable generator in accordance with the number of phases, frequency, output voltage, and speed that suit your load characteristics (e.g. three-phase, single-phase, 1500 rpm 50 Hz or 1800 rpm 60 Hz).
  • Always choose the products of reliable companies with proven quality, adequate after-sales services, and the ability to provide required spare parts, quality certificates, and fulfilling warranty conditions.
  • Make sure that a protective system including functions like low oil pressure, engine temperature warning, high speed, over-voltage, low voltage, and short circuit are available with the generator.
  • Pay attention to the utilization of approved and certified electronic boards, electrical switches, and breakers in the generator’s automatic control panel.
  • Decide whether the generator energy will be transferred automatically or manually.
  • Be aware of the location altitude where the generator will be utilized. As the altitude increases, the amount of oxygen decreases, resulting in power losses specified by the engine manufacturers. (e.g. altitudes higher than 1.000 m)
  • Be aware of the annual average temperature (° C) of the location where the generator will be installed. As the ambient temperature increases, there will be a performance decrease in the generator set at the rates specified by manufacturers.
  • Provide measurement for total power consumptions and current values of electric motor loads with higher inrush currents (e.g. for some type of motor loads Inrush current can be 4-5 times higher than average values).
