Abstract
The teaching aspects of protective relaying is discussed. The existing practice is to teach fault analysis and protection methods on the basis of a steady-state concept of unbalanced power systems. However teaching protection relay design requires analysis of the fault transients associated with power apparatus and instrument transformers. Appropriate tools to simulate dynamic behavior of a power system are needed in this case. A dynamic testing simulator called DYNA-TEST, to be used as a teaching tool, is proposed. The simulator can be implemented with almost any common mainframe, using readily available supplemental hardware and software. As an example, teaching experiments involving digital algorithms for distance relaying are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
