About this calculator
The Autonomia Gerador is a simple and effective online tool for calculating the autonomy of a power generator, considering fuel consumption and load percentage. It's ideal for construction projects that require electrical energy, especially in remote areas or with limited access to the electrical grid.
To calculate autonomy, simply enter the fuel tank volume and fuel consumption per hour, plus the load percentage. The formula used is the classic L_tanque / (consumo · carga%), which provides a precise and useful result for planning the necessary energy.
It's essential to remember that the calculated autonomy is only an estimate and can be affected by factors such as generator efficiency, environmental conditions, and regular equipment maintenance. So, it's crucial to consider these factors when planning energy for your project.
Frequently asked questions
What is the load percentage?
The load percentage is the maximum percentage of the generator's power being used. For example, if the generator has a power of 10 kW and the load percentage is 50%, that means 5 kW are being used.
How can I calculate the autonomy if I don't know the fuel consumption per hour?
If you don't know the fuel consumption per hour, you can research the information in the generator's documentation or contact the supplier. Additionally, you can use the formula L_tanque / (power · load%) to calculate the autonomy, as long as you know the generator's power and load percentage.
What is the difference between autonomy and operating time?
Autonomy refers to the time the generator can operate without needing refueling, while operating time refers to the time the generator can operate in general, including refueling time.
Can I use the Autonomia Gerador to calculate the autonomy of other types of generators?
Yes, you can use the Autonomia Gerador to calculate the autonomy of other types of generators, as long as you know the fuel consumption per hour and load percentage. However, it's essential to remember that the formula used is an approximation and may not be accurate for all types of generators.
