Key Features
1. Comprehensive Feeder Protection
- Phase and ground overcurrent (50/51, 50N/51N) with directional elements
- Sensitive earth fault (SEF) and thermal overload protection
- Under/overvoltage and over/underfrequency monitoring
- Rapid fault isolation to minimize system downtime
2. Advanced Control & Automation
- Bay-level breaker control and interlocking
- FlexLogic™ programmable automation for custom protection schemes
- Supports auto-reclose, conditional interlocks, and system-specific logic sequences
3. Monitoring & Recording
- Accurate real-time metering: voltage, current, power, frequency, energy
- Sequence-of-events (SOE), fault/event logs, and oscillography
- Time-stamped records for diagnostics and regulatory compliance
4. Communication & Integration
- Multi-protocol support: IEC 61850, Modbus TCP/RTU, DNP3, IEC 60870-5
- Ethernet connectivity with optional redundancy
- Seamless integration with SCADA, DCS, and substation automation systems
5. Industrial-Grade Reliability
