Siemens Portable Switch for Temporary Isolation

Whilst traditional in-line tension disconnects provide line crews with a way to temporarily isolate a line at non-designated switching locations, however, the lack of a ganged switching capability creates operational inefficiencies due to:

• Restrictions in load breaking capability
• Restrictions in load pickup
• The risk of ferro-resonance due to single phase switching operations
• The additional time to isolate upstream devices prior to operating the in-line disconnect

Therefore, it is common that a switching sheet may require an additional 20 or more items to remove load or to provide precautionary isolation prior to breaking bridges or opening the in-line disconnect. Siemens has addressed all these problems by adapting the switching unit of the proven Fusesaver circuit breaker into a pre-configured 3-phase synchronous portable switch kit. The switch units are suitable for in-line tension mounting for simple installation and visible isolation.

Key user benefits

• Self powered from on board battery
• No configuration required
• Reduced day to day operating cost as switching crews can operate from an EWP or ground
• Reduced potential for operator error during switching procedures with simple one button operation
• Complete self contained carry case
• Access live data from the line using the Siemens Connect PC application
