This paper is concerned with teaching aspects in the protective relaying field. Present practice in this field is to teach fault analysis and protection methods based on the steady-state concept of unbalanced power systems. Teaching of the protection relay design issues 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 (DYNA-TEST) Simulator concept, to be used as a teaching tool, is proposed in this paper. 1989 IEEE
