With the 4-MJ synthetic testing facilities completed, KERI can perform the circuit breaker testing up to 420 kV, 50 kA ratings. The short-line fault test is one of the necessary test items which are required for the circuit breaker, and in order to perform the short-line fault test KERI(Korea Electrotechnology Institute) has used the "new artificial line" which has small dimension and is easy to generate the saw-tooth wave. This paper describes the following items of the new artificial line. -Description of 4-kinds of artificial lines and determination of the circuit parameter of artificial line. -TRV characteristics of saw-tooth waves for each circuit. -KERI's artificial line.
