I(A)=P(W)/VL-N(V)× PF × 3 The currentIin amps is equal to the powerPin watts divided by the product of the line-to-neutral voltageVin volts, the power factorPF, and 3. This formula calculates the total current for all three wires in a three-phase system. You will need to ...
Amp to Watt conversion: Learn how to calculate watts from volts and amps in both DC and AC circuits. Understand the impact of power factor & reactance on the calculation.
You can calculate kilo-volt-amps (KVA) from three-phase kilowatt (KW) by following a formula. This formula can be used for information regarding industrial motors and home emergency generators, provided you know the power factor. Alternatively, the power factor can be measured by finding the di...
In three-phase AC circuits, which are widely used for industrial machinery, large farms, or high-power equipment, converting amps to watts requires a slightly different approach than single-phase systems. The formula depends on whether you’re usingline-to-line voltage (VL-L)orline-to-neutral ...
Let’s calculate this example: STR10N6/208. From the STR data sheet we find out the maximum power is 6000 watts, the efficiency is 90% and the power factor is 0.85. Although the STR will operate down to 180Vac by design, in this example it will be powered via 208Vac, 3 phase. We...
