Credit: 3 CPD

Length: 23 pages

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.
