More Information
Summary:Time delay means for actuating a protective bypass switch for series capacitors comprising a bellows device containing a gaseous medium, a valve means pneumatically connected to the bellows, and an adjustable control orifice device, the control orifice being effective to release the gaseous medium from the bellows at a predetermined rate when an overcurrent condition is sensed on the line, the bellows being effective to actuate the protective switch a predetermined time after the overcurrent is sensed.
