System Protection and Monitoring

SKU: TDSPM00CENDuration: 60 Minutes

The purpose of this course is to teach participants the principles of protection and monitoring in a transmission and distribution (T&D) system. The course explains the role of protective devices, system grounds, and monitoring and control equipment. Techniques for installing or replacing ground rods, arrestors, and fuse links are presented. The course also describes how monitoring and control equipment is typically used in a T&D system. At the conclusion of this course, participants should be able to explain how system grounds, arrestors, and fuse cutouts are used to protect T&D system components. They should also be able to describe the basic function and features of a SCADA (Supervisory Control and Data Acquisition) system.
