phase to ground voltage calculator
Calculate phase-to-ground voltage in single-phase and three-phase systems. Essential for power distribution, grounding checks, and electrical safety.
3 phase voltage to ground
In three-phase circuits, to obtain phase-to-ground voltage from line-to-line voltage, divide that voltage by sqrt{3}. In single-phase circuits use the line-to-neutral voltage.
Formula & Table Summary:
- Single Phase: VPG = VLN
- Three Phase: VPG = VLL / √3
electrical grounding voltage
A Phase to Ground Voltage Calculator can be used to check the voltage between a live conductor and ground on a single or three-phase circuit as a safety and equipment verification mechanism.The calculator can be applied by engineers, electricians, and students troubleshooting a power distribution network on the grounding, motors, and grounding checks. Just key the type of system and voltage and you will get the results immediately.
ground fault voltage
| System Type | V_LL (V) | V_LN (V) | V_PG (V) |
|---|---|---|---|
| Single-phase | — | 120 | 120 |
| Three-phase | 400 | — | 230 |
