Four zones of phase and ground distance protection.
Quadrilateral (and/or mho) characteristic for ground distance protection.
Adaptable directional element selects best measurement technique (negative-sequence or zero-sequence impedance).
Independent timers for phase and ground distance time-delayed trips.
Any zone may be set forward or reverse.
Patented Mirrored Bits technology for communications-aided tripping schemes (eight independent channels in each relay).
Flexible communications and RTU features including three independent ports; ASCII, multidrop, and binary protocols; compressed ASCII commands; Fast Meter/Fast Operate support; Remote control bits for SCADA/RTU functions.
