Abstract
A distribution line powered switchgear control is provided which reliably initiates switchgear operations with stored energy. Stored energy is preferably maintained in a plurality of devices including a power capacitor. The power capacitor is preferably charged by a fast arming circuit which preferably selects among a plurality of independent power sources. The switchgear control additionally isolates sources of stored energy so that depletion of one does not affect the others. Further the switchgear control will preferably prevent closing of the switchgear unless sufficient energy is stored to allow the control to initiate a subsequent opening of the switchgear.
