OC and SC Test on Synchronous Generator — Lesson 12

This lesson covers the intricate details of salient and non-salient pole synchronous machines. It delves into the process of drawing phasor diagrams and the conditions under which these machines operate. The lesson also explains the difference between generator and motor modes, and how power is delivered or absorbed depending on the mode. It further discusses the impact of field current and bus voltage on the operation of these machines. The lesson concludes with a detailed explanation of short circuit and open circuit tests on non-salient pole synchronous machines. For instance, it explains how to calculate the value of Z by measuring the short circuit current and the open circuit voltage.
