| Modern electric power systems performance depend significantly on the operation of circuit breakers. Circuit breaker are used to detect disturbance in the electrical network and to protect the sensitive equipment and costly instruments such as: generators, transformers, and many more. So, they must operate within extremely tight tolerances especially at the electrical network that operate under a short circuit fault conditions. Evaluation of work efficiency for circuit breaker is an important procedure for demonstrating its ability to curb fault currents, especially short circuit currents and for optimizing reliability of network. This paper aims to design a three-phase test circuit used to evaluate the performance of high voltage circuit breaker under short circuit fault by simulation. By this method, the difficulties of practical tests will be overcome, where it doesn't need high electrical power of real sources, unlimited flexibility to adjust the elements value of test circuit, safe from the risks, and economic because it dependent on modeling. | ||
