DC Circuit Switching Transients

Course No. E-3020

Credit: 3 PDH

Course Fee: $86.85 Purchase course

Subject Matter Expert: George T. Hummert, Ph.D., P.E.

 

Overview

This course is intended to benefit engineers who design, use, inspect, or repair circuits that contain DC power sources and accompanying DC components. Application of DC circuits includes control, instrumentation, and motor excitation.

Whereas both AC and DC circuits as well as transmission lines are susceptible to transient phenomena, DC components are particularly subjected to transients caused by current interruptions that routinely occur when circuits are de-energized. Simply closing and opening a switch, for example, can cause unintended radio-frequency interference and/or contact degradation. The course is intended for engineers who have knowledge of basic circuit theory and circuit components, such as resistors, capacitors, relays, contactors, and switches.

The course will cover circuit configurations and components typically encountered that become part of unintended transient phenomena. The course will include an overview of low-voltage arcing characteristics that become part of the transient response mechanism.

To receive PDH credit, the student must take a multiple choice quiz of twenty (20) questions.

 

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

  • Ability to recognize circuit configurations that harbor potential transient problems
  • Techniques for reducing or eliminating problem sources
  • Ability to estimate available energy within transients
  • Ability to derive equivalent circuits to model first-order transient behavior
