dimensioning
with this tool you can calculate the power of an generating set depending on the electrical consumers load.
Input of the consumers load
All inputs are rated in kilowatts
Electric motors in direct starting
Electrical motors rated power.(7 to 9 - times higer start currents)
Electric motors with star-delta-starting
Electrical motors rated power.(3 to 4 - times higer start currents)
electric motors frequency converter starting
electric motors steered by frequency converters.
Ohm resistive load
el. heating etc. consumer load is same as rated while starting.
electronic consumers
lights, IT-systems etc. consumer load is same as rated while starting, but voltage get transformed
Load steps 1 - 3
If you don´t have to start all the load in the first step you can input the load in 3 diffrent steps with an time delay. You can reduce the power of the generating set.
regulation class
please specify the regulation class.
- G1 - voltage dip - 15%, frequency dip - 7%
- G2 - voltage dip - 20%, frequency dip - 10%
- G3 - voltage dip - 25%, frequency dip - 15%
power reserve
specify the reserve in percent.
