The formulas you are looking for are, single phase kW = I x E x pf/1000. For three phase kW = I x E x 1.73 x pf/1000.
Since the breaker that is installed on the generator set will be sized to the output of the 30 kW generator, the load will stay connected until the thermal trip of the breaker trips the load off line. This will be in the matter of seconds before it happens. To handle a 75 kW load and depending if it is an inductive or a resistive load you will need at least a 80 to 100 kW generator.
To power a 30 kW air compressor, you would typically need a generator with a capacity of at least 37.5 kW to account for starting surges and ensure reliable operation. It's advisable to choose a generator with a higher output, such as 40-50 kW, to provide a safety margin and handle any additional loads. Make sure the generator is compatible with the air compressor's voltage requirements as well.
At 746 watts per horsepower (electric) a 35 kw generator would require about 470 horsepower. Round that up, and allowing for control loop margin and mechanical losses, I would guess that a 35 kw generator should need a 500 or 600 horsepower engine.
To convert kVA to horsepower (hp), you can use the formula: 1 kVA = 0.746 kW, and then 1 kW = approximately 1.341 hp. A 62.5 kVA generator can produce about 50 kW (62.5 kVA × 0.8 power factor). Therefore, the generator can provide roughly 67 hp (50 kW × 1.341 hp/kW).
A 40 kVA generator refers to a generator with a power output capacity of 40 kilovolt-amperes. This measurement indicates the apparent power, which is a combination of real power (measured in kilowatts, kW) and reactive power. The actual usable power will depend on the power factor of the generator, typically ranging from 0.8 to 1.0 for most applications. Therefore, a 40 kVA generator can provide between 32 kW to 40 kW of real power, depending on the load and its power factor.
5.274 KW
Depends upon the Kw rating of the generator. The higher the Kw rating the more fuel will be used.
A 5.5 kW generator produces 5,500 watts of power. This is the maximum power output that the generator is capable of producing under optimal conditions.
Since the breaker that is installed on the generator set will be sized to the output of the 30 kW generator, the load will stay connected until the thermal trip of the breaker trips the load off line. This will be in the matter of seconds before it happens. To handle a 75 kW load and depending if it is an inductive or a resistive load you will need at least a 80 to 100 kW generator.
It depends on the total connected load (KW) of the house. If the total connected load is about 20 KW the alternator generator should be designed to meet peak 20 kw load
A 5 kW generator would turn it over but if the full 30 hp of mechanical power is needed, that would require about 30 kW of electric power from the generator.
To power a 30 kW air compressor, you would typically need a generator with a capacity of at least 37.5 kW to account for starting surges and ensure reliable operation. It's advisable to choose a generator with a higher output, such as 40-50 kW, to provide a safety margin and handle any additional loads.

Frequency is the speed that the generator revolves, not the sizing of the generator.
