Vacstat vacuum interrupter monitor  


Theory of Operation

The new VacStatä vacuum interrupter monitor technology is a breakthrough in vacuum switching technology.

  1. A simple device is attached to the vacuum interrupter during manufacturing. This device monitors the interupter to determine if it has vacuum or not.
  2. If there is vacuum, the light via fiber optics will have a continuous path.
  3. If there is no vacuum, the indicator will turn to the orange flag to let the operator know there is a problem. The remote status contact will provide a signal that notifies the user there is a problem Electrical operation of the switch is blocked.
Vacstat in Normal Operation
The signal continuously monitors vacuum
using a fiber optic signal.

Vacstat in Problem State
The signal is blocked therefore
electrical operation is blocked.
