Implementation in electrical power transmission system and higher voltage level operation & execution of power systems require circuit breakers required of higher interrupting capability Instantaneously. To make ensure that interrupting capability, circuit breakers must verify and prove the TRV withstand capability and specified according to standards. To test high voltage circuit breakers, a direct testing using power system network or a short-circuit alternators are not feasible and practical solution obtained. But synthetic testing is an one of the equivalent economical method and evaluated for testing of high voltage circuit breakers. In a synthetic test circuit, it is very quite complex to choose and make circuit components value for a desired TRV envelope. This paper purposes a synthesis process to design synthetic test circuit to generate four-parameter TRV envelope for circuit breaker testing. By using proposed approach a synthetic test circuit has been designed and simulated in MATLAB to generate a four-parameter TRV envelope for a 145 kV, 40 kA rating circuit breaker used.
