المميزات والفوائد
- Numerical direct-digitisation measurement achieves 0.5% accuracy for both protection and metering functions simultaneously, enabling Sepam to serve as the protection relay and revenue-quality current meter in the same unit.
- Integrated front panel HMI with real-time measured values and timestamped event records enables local fault investigation without laptop or communication system, reducing mean-time-to-diagnose after MV fault events.
- Pre-wired CT/VT test plug sockets allow relay testing and setting verification during commissioning and maintenance without disturbing primary circuit wiring, reducing outage duration for relay test programmes.
- IEC 61850 Edition 2 GOOSE communication enables high-speed bus protection schemes and relay-to-relay communication for complex substation protection architectures in industrial and utility substations.
- Motor protection variant (S20M/S40M) provides comprehensive motor starting supervision, thermal protection, negative phase sequence, and differential protection for large MV motor applications.
- Parameter setting software (SFT2841) enables relay settings to be prepared offline, verified by simulation, and downloaded via front panel USB, reducing field setting time and configuration errors during substation commissioning.
- Proven reliability in Saudi Arabia's harsh ambient temperature conditions across decades of installation at outdoor substations, process plant switch rooms, and coastal desalination facilities.
التطبيقات الصناعية
