Protection functions include restricted ground fault (zero sequence differential), split phase protection, differential protection (In-Zone Transformer protection), loss of excitation, sensitive directional ground, current unbalance, overcurrent protection, overexcitation protection, abnormal voltage frequency protection, synchronism check, and a whole suite of under- and overvoltage, and overcurrent functions.

Note: Only available with firmware version 4.4 or above.
