Line-to-neutral voltage is what times the line voltage?

Explanation:
In a balanced three-phase system, the line-to-line voltage is √3 times the line-to-neutral voltage. So the line-to-neutral voltage equals the line-to-line voltage divided by √3, which is about 0.577 times the line voltage. This is why line-to-neutral is 0.577 of the line voltage. For example, with a line-to-line voltage of 480 V, the line-to-neutral voltage is 480 / √3 ≈ 277 V.
