Abstract
Three synthetic test circuits to verify the interrupting performance of UHV circuit breakers (765kV, 63kA, 50Hz) are compared on aspects of equivalence, operation, required capacitive energy and applicability. The comparisons show that, although each circuit has its own merits, the EPIC circuit appears to be very attractive. The EPIC circuit not only saves on capacitive energy but has also a good equivalence with the direct test circuit
