Synchronous Motor Starters (Part 2 of 2)

This video, published by Columbia Gorge Community College, is the second part of a two part lecture on synchronous motor starters. The lecture covers the challenges and methods of starting synchronous motors and provides an overview of various types of synchronous motor starters. In this video, presenter Jim Pytel discusses the "coordination and protection mechanisms inside a DC (direct current) exciter circuit." Additionally, Pytel examines "the operation of components like the field discharge resistor, the field contactor and field discharge switch, the polarized field frequency relay (PFFR), out of step relay (OSR), and loss of excitation relay (LOE)."

This video runs 18:31 minutes in length. The first part of the lecture is available to view separately
