Since the topic of this post focuses only on 3-phase relationships, and not on transformers, we will only discuss where the 3-phase electrical power comes from…the transformer secondary winding. We will also discuss the voltages in each electrical system type and how they are derived. WebFloating voltage and modern equipment equals fried equipment or, at best, things not working right because they aren't inside the 25% tolerance to function on low voltage DC because the devices are grounded. High-leg delta service is supplied in one of two ways. One is by a 3-phase transformer (or three single-phase transformers), having four wires coming out of the secondary, the three phases, plus a neutral connected as a center-tap on one of the windings. Another method (the open delta configuration) requires two transformers. One transformer is connected to one phase of the overhead pri… supply chain infographic template
