Webindicate transformer kVA/2. 3. The impedance of the cable and two-pole switches on the system must be considered “both-ways” since the current flows to the fault and then returns to the source. For instance, if a line-to-line fault occurs 50 feet from a transformer, then 100 feet of cable impedance must be included in the calculation. WebCalculating KVA to AMPs For Generators. One KVA equals 1,000 volt-amps, and is calculated by multiplying voltage and amps. KVAs are converted to AMPs. Our KVA to AMPs chart allows you to see exactly what kW or voltage the given KVA rating converts to so you can safely and adequately power your generator without the worry of a power overload ...
