A. Introduction Three phase transformers are used throughout industry to change values of three-phase voltage and current. Since three-phase power is the most common way in which power is produced‚ transmitted‚ and used‚ an understanding of how three phase transformer connections are made is essential. In this section it will discuss different types of three phase transformers connections. A three-phase transformer is constructed by winding three single-phase transformers on a single core. These

chapter dedicated to Phase I and Phase II of the tender evaluation process. Essentially in each phase you are doing risk identification and risk quantification. The assignment is to compare the two phases discussed and then answer questions that compare the two phases. Since each phase is designed to serve a different purpose‚ you can’t really say one phase is better than another. Both phases are important in order to understand the risks during the tender evaluation process. Phase I that is described
