i want to know how to measure practical the power out of generator i have generator and i lost the Manuelthere's no info on the generator except the voltage and Frequency
Instead of relying on immigrant labor, you should read the manual to see what the power rating is. You should be ashamed of yourself.
before making judgment u need to know people situation yeah I'm ashamed from telling u the truth I'm from Libya and we r in war i bought the generator (with triple of it price) and they told me it's 4KVA and i want to make sure of that , i have the Manuel but there's no 6200 model on it there's 2500 4000 6000 7000 the 6000 generator has 25 L tank mine has 15 L so i cant tell if it has the same specifications so i want to make sure by measure it practically i tried to run 2500 watt sharp dishwasher for 18 min and it's worked well ~~
I don't think there is any easy way other than loading it up and seeing when the voltage drops to below the minimum you require. You can get a ball park idea by just looking at the physical size and comparing it with other known generators.
Connect a high power AC current meter or watt meter between the output and load. Connect a voltage meter across the load. Increase the load until voltage drops below 10% of its rated voltage. Read the wattage or current from meter. Or calculate it W current X voltage ( obtain from meter) The simple way without those expensive current meter or watt meter and variable load Connect some known wattage device like heaters in parallel one by one until you see the voltage drops down 10% below its rated voltage. Add all the loads wattage is the approximately answer.
The only practical method of measuring generator output is with a frequency meter, power meter, or alternatively, a voltmeter and ammeter, and an adjustable load bank. If it is a portable, a.c. generator, you could connect known loads to the generator, such as portable space heaters and light bulbs. As you load the generator up, you will eventually see the frequency dip significantly, which will indicate that the generator has achieved its full load.
