The LineBOSS™ NBS, Nielsen Bypass Switch, was originally designed in 1972 by Carl Nielsen, P.E. to allow non-interrupting bypassing and energizing (cut-in or cut-out) fixed booster transformers. The NBS switch now provides continuous power to load-side customers when energizing or de-energizing one, two, or three phase fixed booster, auto-booster, and regulator transformers as required by voltage conditions or routine maintenance or replacement.
LineBOSS GBS 15 kV – 72.5 kV Sidebreak Loadbreak/Ground Switch
The LineBOSS™ loadbreak grounding switch, GBS, is uniquely designed to provide loadbreak, open gap clearances and line grounding for applications in substations or pole line switches. The GBS is available for two arm substation construction with switch bases manufactured to adapt to existing structures, or factory unitized on a single steel crossarm. The GBS is available with fused disconnects for additional system safety requirements. Control mechanisms are built with safety key interlocks to prevent the isolator (loadbreak) switch and the grounding switch from errant closure of both switches.
