In the following diagram, corresponding to the installation of a motor in Turrialba, the Δ has a sequence of phases named with the value s = 0; where:

s = 0 means that the star has a positive phase sequence.

s = 1 means that the star has a negative phase sequence.

Let them be lines A, B and C, identified by the numbers 1, 2 and 3 respectively.

If between line 1 and the line that precedes it (according to the phase sequence), there is a voltage of V = 513 ⦟ 46° V and if, on the other hand, L has a value of 0.45 H and also R it has a value of 745 Ω.

Determine the power factor of the three-phase apparent power that the load demands from the source.
