Single & Three Phase Line kVA calculator is an online tool used in electrical engineering to measure the unknown quantity by two known quantities applied to the below formulas for single phase and three phase connection.

0000004184 00000 n 0000005965 00000 n The maximum current per 3 phase leg appears to be 3 x 9.1 Amps @ 230 VAC nominal (3 phase = 3 wire connection) for the 6,000 Watt model. Be aware that it's much better to calculate your motor currents separately and add them, because if you calculate it as one 500kw motor you will get a skewed reading.

To calculate kVA, you need to enter the known values of voltage and the current into the respective fields.
