This microprocessor-based protection relay utilizes a highly integrated, system-on-chip processor to analyze signals from current and voltage transformers. Its operation is governed by digital logic algorithms that ensure precise and reliable control outputs. Housed in a compact, sealed, and maintenance-free enclosure, the device boasts exceptional immunity to electromagnetic interference, making it an ideal solution for harsh environments and space-constrained installations like Ring Main Unit (RMU) systems. Its ultra-low-power design guarantees reliable and high-speed activation of all protection functions under any condition.
Key Features
- Robust & Compact Design: A sealed, anti-interference metal case ensures durability in demanding conditions, with a form factor tailored for compact RMU compartments.
- Flexible Protection Schemes: Features comprehensive and configurable protection functions, including phase time-overcurrent with three standard IEC inverse-time curves, all easily enabled or disabled via control words.
- Integrated Metering & Control: Provides extensive measurement capabilities (V, I, P, Q, S, PF) and includes 7 digital inputs and dedicated relay outputs for remote control functionality.
- Advanced Communication & Data Logging: Equipped with an RS-485 interface supporting open communication protocols for SCADA integration, and a large non-volatile memory storing 100 detailed event records.
Applications
-Secondary Distribution Networks: Primary protection and control for feeders in industrial, commercial, and utility power systems.
-Ring Main Unit (RMU) Systems: Ideal for the protection of switchgear in compact RMU configurations.
-SCADA and Automation: Facilitates remote monitoring, control, and data acquisition in automated power distribution networks.
-Critical Circuit Protection: Ensures reliable fault detection and isolation for cables and overhead lines.
