Answer 1

In a star connected three-phase system, the phase voltage Vp is the line voltage divided by the square root of 3. Given a line voltage of 430 V, the phase voltage is approximately 248.1 V.

Step-by-step explanation:

The subject of the question involves the concepts of electricity and magnetism in the field of Physics, specifically dealing with an inductive load connected to a three-phase supply in an industrial setting. To find the phase voltage (Vp), we must remember that in a star connection, the phase voltage is equal to the line voltage divided by the square root of 3 (Vp = Vl/&sqrt;3).

Given the line voltage Vl is 430 V for a star (or Y) connected three-phase system, the phase voltage (Vp) can be calculated as follows:

Vp = Vl/&sqrt;3 = 430 V / &sqrt;3 ≈ 248.1 V

Therefore, the phase voltage Vp in this industrial setting with the given parameters is approximately 248.1 V.
