What is the neutral conductor? What is the neutral conductor for? Why do only 3 wires enter the transformer and 4 leave? There are many questions that arise regarding this conductor. Let's try to explain some of them to you. The neutral conductor is used as a return path for the electric current. It is created through a star configuration of the transformer, coming out of the center of this star (3 coils with 3 common points interconnected). The neutral conductor does not present electric current under conditions of balanced three-phase loads, but if there is an imbalance of these loads, it serves as a path for the current to flow. Since in practice it is very difficult to install balanced electric loads, we can assume that in most cases the neutral conductor will have electric current flowing through it, contrary to what some people think. The neutral conductor is grounded to ensure a return path for these electric currents (connected to the ground). This grounding is normally done at the transformer output and in the case of distribution networks, the grounding is done at the base of the posts and at the delivery points (meters). A common effect that you may have noticed in your home is the so-called “floating neutral” or “open neutral” effect. When the neutral is broken, the three-phase system loses reference and voltage rises and falls in the network when measured between phase and neutral. This effect usually creates an environment where some lamps increase their brightness greatly (voltage rise) and others remain dim (voltage drop). In this type of situation, it is very common for electronic equipment to burn out due to network instability. When we hear someone say that they have 127V phase-neutral voltage and 220V phase-phase, we are referring to the phase and line voltage respectively. The mathematical relationship for this calculation is the square root of 3, which is approximately 1.732. If we multiply any voltage between phase and neutral by 1.732, we will arrive at the value of the line voltage (phase-phase) and vice versa. In Brazil, there are several voltage levels between phase and neutral. Did you know that we can have any phase-to-neutral voltage value, including 220V? In some states in Brazil, the phase-to-neutral voltage is 220V and the phase-to-phase voltage is 380V. We can build transformers for any phase-to-neutral voltage value. The industry, for example, works with voltages of 440V between phase-to-phase and 254V between phase-to-neutral. In short, although the best-known voltages are 127V phase-to-neutral and 220V phase-to-phase, we can have any line and phase voltage value. It all depends on the construction characteristics of the transformer. Do you have any questions? Leave them here in the comments and we will try to answer them as soon as possible. ????
