Key Features
Comprehensive feeder protection: multi‑stage overcurrent (50/51), directional overcurrent (67), earth fault (50N/51N), sensitive earth fault (SEF), high‑impedance fault (HIZ) detection, phase discontinuity (46PD), and thermal overload protection
Advanced control functions: multi‑shot auto‑reclose (3‑phase), breaker failure protection (51BF), and load shedding/restoration (6‑stage frequency‑based)
Integrated measurement: true RMS current/voltage, power (kW/kvar/kVA), energy metering (kWh/kvarh), and power quality analysis
Arc‑fault detection: 3‑channel system for primary equipment safety supervision
Fault location: accurate fault distance calculation (±2.5%) for phase‑to‑phase and phase‑to‑earth faults
Flexible configuration: customizable logic via PCM600 tool, role‑based user authentication (4 levels), and front‑panel HMI with graphical display
High interoperability: full IEC 61850 support (GOOSE, MMS, process bus), peer‑to‑peer communication for busbar protection via GOOSE
