WebHigh-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. Web29 de ago. de 2024 · Transformers create the most important connection between the load and supply systems. The efficiency of transformer directly influences its operation and aging. The transformer’s efficiency is generally in the range of 95 – 99 %. The efficiency can be as high as 99.7% for great power transformers with very low wastes.
