two generators are running in parallel and one of them loses excitation

In this blog post, we will discuss what happens when two generators are running in parallel and one of them loses excitation. Excitation is the process of providing a magnetic field to the rotor of a synchronous generator, which enables it to produce electrical power. When a generator loses excitation, it can no longer supply […]
