## L-L and L-N voltage

In an electrical system, there are two ways to measure voltage: line-to-line voltage and line-to-neutral voltage. Here is the difference between the two: What is line to line voltage? The LL voltage is the electrical potential difference that exists between two phases of a three-phase or two-phase system. It is measured between two conductors (or phases) of …

## Voltages and phases for electrical equipment

Electrical equipment is commonly connected to single-phase, two-phase and three-phase systems with different voltages, it is very important to identify the number of phases to which the voltage refers, because there are cases in which there are equal voltages but different number of phases. For example, the case of the 220V voltage that in the …
