- 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.
