"WebMar 6, 2024 · V pq = (√3V LN cos30°) × 2 = 3V LN (equation 9) Thus, the voltage available to the relay for a phase-to-ground fault on the ungrounded system is three times the line-to-neutral normal voltage. Usually, the VT ratio of primary V LN: 69.3 V is used so that the maximum solid ground relay voltage would be 3 × 69.3 = 208 V. " - Earth fault monitoring
