Key Features and Engineering Advantages
Advanced Protection Suite:Provides both non-directional and directional overcurrent and earth-fault protection, ensuring sensitive fault detection even in complex distribution topologies.
High-Speed Busbar Protection:Supports GOOSE messaging to enable high-speed busbar protection via interlocking, often eliminating the need for expensive dedicated busbar relays.
Integrated Bay Control:Features dedicated push-buttons and software logic for the local and remote control of circuit breakers and disconnectors with built-in interlocking safety.
Graphical LHMI:The high-resolution display allows operators to visualize the bay status through single-line diagrams and phasor views, facilitating rapid diagnostic assessments.
Modular "Plug-In" Design:The relay unit can be withdrawn from its case for testing or maintenance without disturbing the field wiring, significantly reducing downtime.
Arc Flash Protection (Optional):Can be configured with ultra-fast arc flash detection sensors to protect personnel and equipment from internal switchgear faults.
