A Solid-State Synchronous Switch for Use in Transient and Modeling Studies

This paper describes a new synchronous switch employing solid-state electronics, that extends the usefulness of the CRO in viewing transient phenomena in electrical circuits by means of a repetitive trace on the CRO. This device is particularly useful in normal research projects and has a unique place in repetitive and "one-time" switching in power system models such as the conventional transient analyzer and the newer EHV simulators.
