Overcurrent Protection of Power Systems Seminar. This seminar will describe how to apply and set overcurrent protection systems. Topics include application of fuses, reclosers, and overcurrent relays to provide coordinated short circuit protection of radial distribution systems. This includes overcurrent protection of busses, transformers, lines and cables.
 
Assuming the attendee has a working knowledge of short circuit analysis of power systems, this course will describe how to apply and set overcurrent protection systems. Topics include applications of fuses, reclosers, and overcurrent relays to provide coordinated short circuit protection of radial distribution systems. This includes overcurrent protection of busses, transformers, lines and cables.
 
Topics will include:
  • Overview of grounding practices for distribution system neutrals (ungrounded, high, or low impedance grounded or solidly grounded)
  • Time/current characteristics of overcurrent protection devices
  • Time/current damage curves of conductors and transformers
  • Application and selection of fuses for protection of distribution systems
  • Discussion of measured quantities, phase, ground, or negative sequence currents
  • Selection and setting of circuit reclosers
  • Measuring principles of time and instantaneous overcurrent relays
  • Selection and setting of time and instantaneous overcurrent relays
  • Coordination of relays, fuses and reclosers with each other
  • Protection complications introduced by networked systems and/or distributed resources connected to traditional radial distribution systems
  • Techniques for “load blinding”
  • Relaying accuracy of current transformers
 
The short circuit computer program ASPEN OneLiner will be used as an example of a computer tool for protective device coordination. However this is not a training seminar on the use of ASPEN OneLiner.
 
Due to time limitations, protection of motors, and generators is not included. Also discussion of differential protection systems is not included. Previous participation in the APEGBC companion seminar “Short Circuit Analysis of Power Systems” would be helpful, but is not a prerequisite as long as the attendee has a working knowledge of short circuit analysis techniques.

What Previous Participants have said about this Seminar:
  • “Excellent presenter. Made a potentially dry topic interesting, thanks to visible passion for it as well as good strong voice to complement slides. Thanks.”
  • “Excellent speaker, encouraged questions and class participation. Very knowledgeable.”
  • “Good speaker (volume and clarity). Good slideshow. Good on screen tools with flipchart backups.”
  • "Very good instructor. Has a good knowledge of the industry."
  • "The seminar content was excellent with many examples from utility."
  • "Charlie is an excellent speaker/presenter. Everything was easy to follow, handouts and materials were clear, and the pace was good (not too slow, not too fast)."
