Phase-to-ground voltage is a crucial concept in electrical engineering, particularly for three-phase power systems.

It represents the voltage between any single phase and the ground. This voltage is essential for ensuring the safety and proper functioning of electrical equipment, as it helps in determining insulation requirements and fault levels.

Phase-to-ground voltage is typically lower than the phase-to-phase voltage in a balanced three-phase system, which helps in reducing the insulation requirements and the risk of electrical shock.

Phase to ground voltage, V_{p-g(V)} in volts is calculated by dividing the phase to phase voltage, V_{p-p(V)} in volts by square root of 3,approximately 1.73.

Phase to ground voltage, V_{p-g(V)} = V_{p-p(V)} / 1.73

V_{p-g(V)} = phase to ground voltage in volts, V.

V_{p-p(V)} = phase to phase voltage in volts, V.

**Calculate the phase-to-ground voltage of a three-phase system with a phase-to-phase voltage of 400 volts:**

Given: V_{p-p(V)} = 400V.

Phase to ground voltage, V_{p-g(V)} = V_{p-p(V)} / 1.73

V_{p-g(V)} = 400 / 1.73

V_{p-g(V)} = 231V.

**Suppose a three-phase system has a phase-to-ground voltage of 277 volts. Calculate the phase-to-phase voltage:**

Given: V_{p-g(V)} = 277.

Phase to ground voltage, V_{p-g(V)} = V_{p-p(V)} / 1.73

V_{p-p(V)} = V_{p-g(V)} * 1.73

V_{p-p(V)} = 277* 1.73

V_{p-p(V)} = 480.
