Simulations of three-phase faults at the generator terminals have shown the existence of
non-zero currents in all three phases for several cycles. Particularly in the application of …

It is postulated that the performance of a multi-break interrupter can be better than that
expected from an extrapolation of the test results on a single-break unit. A computer model …

The equations and parameters of a physical arc model which can be used to compare test
circuits with respect to the thermal and dielectric interrupting interval of SF/sub 6/circuit …

A detailed dynamic arc model may be used to roughly evaluate the interrupting capacity of a
breaker and its influence on the deformation of the interrupted current. In some cases the …

With electric power systems, it is shown by calculations that as the transmission voltage
rises, high-frequency components contained in the fault current could remain until current …

Generator breakers in high-power testing fields, the back-up breakers, have the function of
safety breakers: they have to protect both the generator and the test breaker from being …

The authors use a physical arc model to compare the switching behaviors of circuit breakers
in a direct and two synthetic test circuits with a computer program. It was found that not only …

The short-line fault interrupting ability of gas-blast circuit breakers is limited by arc energy
balance processes very close to current zero. Practical calculation of the energy balance …

This paper reported analyzed results of the transient dynamic arc around current zero of air
blast circuit breakers on the basis of Mayr arc model. It was proved that an arc time constant …

Generator-fed fault currents are subjected to very demanding condition called “Delayed
current zeros”. This unique characteristic of the fault current comes from the very high X/R …
