The basic version of the relay can be extended even later by the addition of extra cards. By using a new method of evaluating current signals, the relay can determine whether C.T. saturation is due to internal or external faults and either trip or stabilize accordingly. Thus this extended relay (type XD1-G SAT) is particularily appropriate for:
•        Different sets of C.T.s
•        Retrofitting
•        Difficulty conditions
•        High-quality items to protect
•        High mains power
•        Motor feeders.
