For mandatory operation regions, the PCS shall be considered in compliance if it provides
an average current greater than or equal to 80% of the pre-disturbance current or other per-
centage defined in the requirements documents during the ride-through event in each of the
voltage ranges specified in the SRD(s), and returns to at least 80% of the pre-disturbance
current level within the time specified in the local standards or regulations.
For momentary cessation regions, the PCS shall be considered in compliance if it provides
an average active current less than or equal to 10% of the PCS rated current during the ride-
through event in each of the voltage ranges specified in the SRD(s), and returns to the pre-
disturbance current level or percentage as defined in the requirements document within the
time specified in the local standards or regulations.
