Selection guide
Wichtiges zur Auswahl des passenden Aggregats
When using power generators, there are various important factors that are crucial for selecting the appropriate generator to ensure a flawless and safe supply of technical systems and equipment. Incorrect sizing of the generator can lead to damage to both the consumers and the generator itself. For this reason, you should have the following requirement data ready for a specific inquiry.
Wichtige Fragen zur Diesel-Stromaggregat-Auswahl
What is the frequency (50 / 60 Hz) and power factor (Cos φ) of the consumers? Are there high inrush currents? Is the installation location easily accessible, and what is its condition? For what duration will the generator be used? What is the total load (in amperes) required?
sample calculation
The following example calculation illustrates the determination of the total active power (P total):
Consumer 1: 200 kW
Consumer 2: 175 kW
Consumer 3: 50 kW
Consumer 4: 25 kW
Total active power (Ptot.): 450 kW
Umrechnung von kW in kVA (Scheinleistung S in kVA, Wirkleistung P in kW):
S = P / cos(φ) = 450 kW / 0,8 = 562,5 kVA
Sie sollten immer eine Reserve von 25% einrechnen, um eventuelle Stromschwankungen zu vermeiden: 562,5 kVA + 25 % = 703,2 kVA
Alle Leistungen sind auf 3 Phasen (Drehstrom 400V) bezogen.
Weitere wichtige Informationen
If the generator is to be operated in grid parallel mode or in peak load operation, it should be noted that only 80% of the power is available continuously.
An electric motor (depending on its type and purpose) can require up to 8 times its power during loaded startup. A generator can temporarily provide twice its rated power.
Renting a Power Generator
We have access to over 2,000 generators nationwide, ranging from 15 to 2,000 kVA. Choose the desired generator and complete your inquiry.
Rent fuel tanks
We offer external, double-walled fuel tanks (IBCs and tank containers) with a capacity of 1,300–11,500 liters that you can rent directly.
Rent transformers
Transformers are particularly needed when paralleling multiple power generators. At HO-MA, you can rent reliable transformers with up to 5,000 kVA.
Lichtmast mieten
Neben Stromaggregaten können Sie bei HO-MA verschiedene mobile Lichtmasten ausleihen und sogar käuflich erwerben. Die Lichtmasten stammen vom Weltmarktführer auf diesem Gebiet und können unglaublich große Flächen ausleuchten.
