Convert 480 volt 60 hz to 380 volt 50 hz generator for international service?
1) Changing Engine Speed to Vary Output FrequencyPresent-day generators consist of an engine directly connected to an alternator to produce electricity. One of the most common ways of changing the output frequency of a generator is to change the rotation speed of the engine.The two factors are related as per the following formula -Generator Frequency (f) = Number of revolutions per minute of the engine (N) * Number of magnetic poles (P) / 120Conversely, P = 120*f/NAs per the above formulae, a 2-pole generator producing an output frequency of 60 Hz has an engine speed of 3,600 rpm. To change the output frequency to 60 Hz for the same generator configuration, the engine speed needs to be reduced to 3,000 rpm. Similarly, for a 4-pole generator, an engine speed of 1,800 rpm produces output of 60 Hz. Reducing the engine speed to 1,500 rpm yields an output of 50 Hz.In the case of small or residential generators, you can alter the engine rpm settings by making a few changes on the control panel of your unit. Follow the steps given below to alter your generator frequency from 60 Hz to 50 Hz:(a) Run your generator engine and tune the frequency meter on your control panel to read 50 Hz.(b) Check the AC voltmeter or potentiometer as the case may be and read the voltage output of the generator. The output voltage decreases as you reduce the frequency and may be lower than the desired value.(c) Adjust the AC voltmeter or potentiometer on your control panel till you obtain the desired output voltage at 50 Hz.(d) By making similar modifications on the control panel, you can increase the frequency from 50 Hz to 60 Hz.(e) If the control panel does not display the frequency, you will need to first connect a device that will measure the frequency while the generator is in operation and then change the engine rpm.Generator controller units undertake real-time monitoring and control of your unit. Built-in protective functions automatically shut down your generator in the case of excess engine rpm or very low output frequency. For addtional information on the functionality of a generator please read the following article, How Generators Work.
What is the output current of a 480 Volt primary 208 volt secondary - 3 phase transformer?
You need to mention the Load connected to find the current.
What size wire for a 4000 amp service?
Generators are rated in volt-amps (va) and may also have a wattage rating. In most practical applications volt-amps and watts are the same. At 240v single phase, 400 amps is 96000 volt-amps, or 96kva. I would be looking for a 100 kva generator. This is a large generator if you are considering it for your home. In most situations you identify critical circuits and place only these on the generator through a transfer switch. This allows for a much smaller generator.
Can you get -5Volts as output when polarity is reversed?
yes.you can get 5v output even when the polarity is reversed. In a 5v battery, if u reverse the polarity, then u'll get the same 5v as output , but in the opposite direction.(i.e.,)-5v(negative 5 volt
A transformer has a primary volt of 240v and a secondary volt of 48v what is the turn ratio?

What causes increase of the output of a generator that should be 220 volt to 400 volt?
It sounds like the field voltage potentiometer is not working or has been turned up. Try turning it down and see if the output voltage goes down with it. If it doesn't then the voltage regulator is not working as the field voltage is regulated from the regulator.
Why gen output of 220 volt increase too 400 volt?
If the output of a generator is increased from 220 volts to 400 volts, it could be due to an adjustment of the generator's voltage regulator or the generator being overloaded. This change in voltage could be dangerous for equipment designed to operate at lower voltages and could potentially lead to damage. It is important to ensure that the voltage output of a generator remains within safe limits for the equipment being powered.
How do you tell generator on 1983 Honda gl 1100 works or not?
Start the generator and check the voltage output at the receptacles on the generator with an AC volt meter.
How many output amps is a 75 KVA generator?
It depends upon the Generator system voltage. For 3 Phase, 600 Volt system, it will be 73 Amps For 3 Phase, 480 Volt system, it will be 90 Amps For 3 Phase, 208 Volt system, it will be 208 Amps
What if my generator sends 120 volts and 65 amps into my 200 amp panel box will it run my well pump connected to a 20 amp 240 volt circuit?
No, the generator must output 220 volts which any generator I have ever seen does.
Can you connect a 230 volt 15 amp air compressor to a 240 volt 50 25 amp generator?
No, it is not safe to connect a 15 amp air compressor to a 25 amp generator. The generator's output exceeds the maximum amperage of the air compressor, which could potentially damage the compressor or cause overheating. It is recommended to use a generator that matches the power requirements of the air compressor for safe operation.
When do you know when a generator is working?
Depending on the type of generator, you can measure the voltage at the output. Assuming it's a regular 120 volt AC generator, the output should measure 120V AC. If it doesn't, you may have problems.
How many watts can be powered by a 9 volt generator?
There is no way to answer without knowing the wattage rating of the 9 volt generator. A generator's wattage rating depends on the size of the wire in it, the wattage of the rectifiers if it is a DC generator, and the horse power of the engine or motor that is available to turn the generator.
How can I connect 3 1.5 volt batteries in series to increase the total voltage output?
To increase the total voltage output, connect the 3 batteries in series by connecting the positive terminal of one battery to the negative terminal of the next battery, and so on. This will result in a total output voltage of 4.5 volts.
Will 13.8 volt output transformer work for 13.5 volt transformer?
yes
What generator size is needed for 0.5 hp 220 volt 1 phase?
The generator should be about ¾ hp.
Why is it that a 2000 watt Honda EU generator not power a 1140 watt high pressure sodium fixture?
The first thing that comes to mind is check the voltage of the HPS ballast. Some ballasts have multi taps so that a variety of voltages can be used to operate the fixture. Make sure that you have connected the generator's supply to the 120 volt tap. Make sure that the generator's breaker is on and that there is the correct voltage at the output. If is is a dual voltage generator make sure that you are plugged into the correct voltage output.
