6.2.18 Fast voltage recovery
The Fast Voltage Recovery feature when enabled, bypasses normal timing operation to
return voltage to an in-band condition as rapidly as possible. This is required for
unplanned and planned load transfers to allow critical loads to be shifted to a transformer
quickly without causing that transformer’s voltage to decrease too quickly.
When Fast Voltage Recovery is enabled in automatic mode and the voltage exceeds either
the Raise or Lower Band edges plus the Fast Voltage Recovery setting, the normal definite
or inverse time delay curve and setting is replaced with instantaneous operation (<0.5
seconds). In all cases, once the normal time delay has been replaced with instantaneous
operation, normal timing will not be in effect until the voltage returns in band. This feature
