ABSTRACT:
A voltage recovery device is configured to provide reactive power to a utility power network at a level and for a duration sufficient to recover the voltage on the utility power network within a predetermined proportion of the nominal voltage, following a fault condition detected on the utility power network. In operation, the voltage recovery device reduces the overall transmission losses in a utility power system.
