Web23 mei 2024 · How do you figure it out? Some uninterruptible power supply (UPS) systems are rated in kilowatts (kW) and others in kilo- volt-amperes (kVA). KW and kVA simply mean 1,000 watts (W) or 1,000 volt-amperes. The basic rule of physics that watts = volts x amps is based on direct current circuits. Web7 mei 2015 · 200kVA = 220V * 303A + 220V * 303A + 220V * 303A. 200kVA = 3 [ 220A * 303A ] So it would be 303A or 304A depending on the strength of your calculator. Be sure to add all those zeros on the kVA. Key to remember is that amperage is always in "per a phase" amperage in these equations and in electrician lingo.
