How do you close a sectionalizer that has tripped when dispatch permission has been obtained?

• A. Turn the control handle to the closed position
• B. Push up on the yellow ring with a hot line tool
• C. Have dispatch close it back in remotely using the SCADA system
• D. Push up on the silver L shaped lever with a hot line tool

Answer: (B)

When a sectionalizer has tripped, it must be reclosed by a physical action at the device using a hot-line tool. The yellow ring is the reset/close point designed for this purpose. By pushing up on the ring with a hot stick, you mechanically reclose the sectionalizer and re-energize the line once dispatch has given permission. This is a local operation that ensures the device is reset safely and intentionally.

Other methods aren’t appropriate here because they don’t engage the device’s reset mechanism correctly. Using a control handle is not the intended close action for this device, remote closure through SCADA isn’t the standard field procedure after a trip, and the silver L-shaped lever isn’t the correct lever for reclosing on this particular setup.
