Question

On a three phase bus, the sequence of phases A, B, and C is observed from top to B if utilized on a three phase, 4wire delta system, which phase will have higher volt to ground?

Answer 1

In a three-phase, 4-wire delta system, the phase with the higher voltage to ground depends on the system configuration. Grounded systems have the neutral point with the highest voltage to ground, while ungrounded systems have all phases with the same voltage to ground (zero volts).

Step-by-step explanation:

In a three-phase, 4-wire delta system, the phase that will have a higher voltage to ground depends on the system configuration. If the system is a grounded system, meaning that the neutral wire is connected to ground, then the neutral point will have the highest voltage to ground. This is because the neutral point is at zero volts and the other phases will have higher voltages with respect to ground. However, if the system is an ungrounded system, then all phases will have the same voltage to ground, which is zero volts.
