Protection of Power Distribution Systems Course

Covers the complex topic of Power System Protection and Coordination. After an introductory overview, we look at short-circuit calculations, fuses, and the protection of distribution transformers, feeders and lines. Finally, we’ll look at substations, overvoltage protection and ferroresonance.

Who should take it: Anyone who is new to power distribution and power systems engineering, or who needs to refresh their understanding of power distribution fundamentals.

Job Positions include: Field Technicians; Distribution Line Workers; Designers; Engineers; Utility Managers; Engineering Managers; System Engineers, Operations Managers; Safety Managers; Communication Line Workers; and Electric Utility Contractors

Introduction to Protection and Coordination of Distribution Circuits Course

Surveys the types and characteristics of faults, and the equipment we protect. We’ll look at overcurrent protective devices, how to estimate the magnitude of fault currents and the asymmetrical and symmetrical components of fault current.

Short Circuit Calculations Course

We develop procedures for determining the magnitude of fault currents, using three methods, ohmic, per-unit, and percent, building a reference table summarizing the equations we develop.

Protection for Distribution Transformers Course

Covers loading capabilities of transformers, withstand curves, fusing ratio and the need to limit fault energy. We also survey specialized equipment such as completely self-protected (CSP) transformers and pad-mounted units.

Protection for Distribution Feeders and Lines Course

Examines the protection of main feeders emanating from the distribution station and the branches that feed local areas. We start with the fuses that protect lines outside the station and then go upstream to the relays that protect the main feeders at the station itself.

Course Code: PC5

Prerequisite: PC1, PC2. PC3, and PC4

Protection for Distribution Substation Transformers Course

We look at faults on distribution substation transformers and how they dictate protection settings, as well as how we deal with transformer inrush and pickup current. We show how to select a primary fuse to protect the station transformer and how to coordinate with upstream and downstream devices. Finally, we’ll look at the complete protection scheme for a real-world substation.

Protection for Overvoltage and Ferroresonance in Distribution Circuits Course

The sources of overvoltage, lightning waves, and how we test equipment to withstand these conditions. We discuss two lightning arrester designs and review the various classes of arresters and their effect on our systems. We wrap up with a discussion of ferroresonance.
