- Understand how to calculate short circuit currents in power systems (including the use of symmetrical components).
- Understand how to develop relay applications and settings for the following parts of the power systems:
- Distribution systems
- Transmission systems
- Generators and motors
- The power system as a whole through system integrity protection schemes.
Day 1: Short Circuit Analysis of Power Systems
The seminar is intended to provide an understanding of how to calculate short circuit levels on three phase power systems. One of the important purposes of calculating short circuit levels is to facilitate the application and setting of protective relays. This seminar (or equivalent knowledge) is a prerequisite for subsequent seminars on distribution, transmission, substation, and generation protection.
This course will present the fundamentals of high-voltage power system protection so that attendees will understand:
- Impact of short circuits on power systems.
- Use of per unit systems and comparison with physical units.
- Symmetrical components.
- Manual calculations of balanced and unbalanced short circuits.
- Network and machine data for short circuit calculations (including power electronic sources).
- Applications of short circuit studies.
- Uses and abuses of fault studies.
- Short circuit model validation.
Basic knowledge of three phase electric power systems. Familiarity with vector mathematics. Electrical technologist or engineering degree.
The course of interest to engineers who are responsible for planning, designing, operating, and maintaining electric power systems with respect to the use of fault studies for rating power equipment. It is suitable for those not familiar with the principles. It is aimed primarily at those interested in understanding how to calculate short circuit currents in power systems.

Day 2: Overcurrent Protection of Power Systems
The seminar is intended to provide an understanding of how overcurrent protection is applied and set on distribution systems. This seminar (or equivalent knowledge) is a prerequisite for a subsequent seminar on transmission, substation, and generation protection.
This course will present the fundamentals of distribution system protection so that attendees will understand:
- Why overcurrent protection works.
- System grounding.
- Time current characteristics.
- Fuse protection.
- Overcurrent relays.
- Selective clearing and 'apples and oranges'.
- Circuit reclosers.
- Complicating factors.
- Current transformers.
Basic knowledge of three phase electric power systems. Familiarity with vector mathematics. Electrical technologist or engineering degree. Prior participation in APEGBC Short Circuit Analysis Seminar or equivalent knowledge.
This course will be of interest to engineers and technicians involved in the planning, design, operation, and maintenance of overcurrent protective devices for electric power systems. 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.
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)."
Day 3 and 4: Fundamentals of Transmission, Generation and System Protection
The course is intended to introduce the subject of transmission, generation, and system protection to enable engineers understand techniques of applying and setting protective relays for transmission and generation equipment. It includes presentations on protection of substation equipment including bus protection and transformer protection. Further, transmission line protection, including directional overcurrent and distance protection systems, will be discussed. It will also cover communications assisted transmission line protection, including line differential protection, single phase tripping and reclosing, generator intertie protection, special protection schemes, undervoltage and underfrequency load shedding. Case studies and examples presented will allow even experienced protection engineers to benefit from the course since some advanced topics will also be introduced.
This course will present the fundamentals of high voltage power system protection so that attendees will:
- Understand how to develop relay applications and settings for the following parts of the power system:
- Substation busses and transformers.
- Transmission systems.
- Generators and motors.
- The power system as a whole through system integrity protection schemes.
- The course includes an overview of disturbance analysis and reading of oscillographic data collected during system disturbances.
- Much of this seminar will use examples of electromechanical and solid state analog relays to provide a foundation of the principles used. However, most of these principles are incorporated using numerical technologies in modern protection systems. A description of the basic components and functions of microprocessor based relays will be provided so that attendees will understand the key features of modern implementation of protection systems.
