John Schwartzenberg of Southern States LLC

This presentation will discuss the application of sub-cycle switching at the medium voltage level for the protection of sensitive loads from distribution system disturbances such as voltage sags and interruptions. Sub-cycle switching systems include the use of multiple switches for dual source applications or a single sub-cycle disconnect switch, with grid forming inverters, for loads fed a single utility source. Case studies will be presented along with information on specification, design and installation of these systems. Attendees will learn about the operational advantages of these technologies, enhancing resilience and reliability for critical loads.
