Imagine the problems if the neutral rose to 1000 V above ground. If you didn't do this, the neutral could float above earth potential, aka ground. That keeps the neutral L2 at 0 V with respect to the local earth potential, and allows the 220 V on L1 to be at that voltage above earth potential. Jimmy Carter RE: 220V Line to Line Generator jdoyle3 (Mechanical)Ĭonnecting a neutral to ground creates a voltage reference point at earth potential. Hopefully someone with local knowledge will post in and confirm that standards in China for one phase of a 220/380 Volts system are the same as in the UK. Unfortunately the ground connection was left on one line instead of being reconnected to the center tap or neutral point. I have had a number of single phase sets supplied from the UK, that were converted from 220 Volts, 50 Hz to 120 Volts, 60 Hz. When 220 Volts is supplied in this environment, it is treated similar to a 120 Volt supply in North America in that one line is hot and one line is grounded.įor 220 Volt, 50 Hz single phase, remove the ground from the center tap and insulate it. Some 220/380 systems are similar to our 120/208 Volt systems in that the wye point or neutral is grounded. If your AVR (Automatic Voltage Regulator) has UFRO (Under Frequency Roll Off) you should set it for 50 Hz (Usually jumper selectable).Īfter setting the UFRO for 50 Hz you should reset the Voltage. Is this a single phase generator or a three phase generator?Įither may be four leads, but the three phase configuration will develop 208/120. RE: 220V Line to Line Generator waross (Electrical) 20 Nov 15 19:46 And then I would also have to increase the size of the generator because I would only be using 1 or 2 thirds of it.Īny help is greatly appreciated. If it is the case that it is not ok to do this, how do other countries use small gensets? Would they use 3 phase generators to make 380/220V to give you the 220V line to neutral? The problem I would have in doing this is that I may only pull from one or two phases, causing imbalance in the generator. I want it to be safe for any 220V load that would plug into it. I know that I would need to use double pole breakers in this case, but I don't know if that offers enough protection. However, my gut tells me that 220V Line to Line can not be used as if it is 220V line to neutral. The generator now operates at 50 Hz and produces 220V across my two lines. I will run my two lines and a ground wire out of the generator, and not use the center-tapped neutral terminal. I have adjusted the voltage regulator so that my line to line voltage is 220V (voltage used in China). I have already lowered the engine speed to achieve 50 Hz, so the frequency problem is solved. The genset is originally configured to run at 60 Hz with 4 leads to produce 240/120V.

Especially for those on a tight budget, warranties should be considered your top priority when investing in the 220 volt gas generator. So don't forget to check out whether that manufacturer gives you a warranty or not before deciding to make any purchase. The 220 volt gas generator will have a warranty or guarantee that backs up the product and promises that if you aren't happy with the product, you can return it for another one or get some money back. If your money is limited, make sure to find something good and cheap. You don't want to spend much on something and regret it later. If all your money can go to purchasing the 220 volt gas generator of good quality for yourself, then do your research and find something that fits your budget. Don't ignore them if you want to own the 220 volt gas generator. Featuresįeatures are essential for specific needs and provide more ease of use in general some features may be necessities while others may not be used much at all, but they're still important in creating your overall satisfaction with your 220 volt gas generator. Things to consider to buy the 220 volt gas generator 1.
