Differential protection relay Vamp protection relays are used for selective protection of subtransmission lines, medium voltage overhead and cable feeders, motor feeders, transformer feeders, capacitor banks, generators, reactors and busbars in power system distribution substations, power plants, industrial power systems, and marine and offshore installations. In addition to a comprehensive range of standard protection functions, the Vamp series also offers bay control, measurements, primary circuit monitoring and communication functionality. TYPICAL APPLICATION MAIN CHARACTERISTICS • Optimized for transformers • High stability against through faults • 2nd and 5th harmonic blocking • Numerical CT ratio correction • Selectable connection groups • Disturbance recorder • Optionally arc flash sensor interface for high-speed trip in case of cable termination faults • Various communication protocols including SPA Bus, Profibus, Modbus, Modbus TCP, IEC 61850, IEC 60870-5-101,IEC 60 870-5-103, TCP/IP, DeviceNet, DNP 3.0 • VAMPSET, a user-friendly, free-of-charge relay management software for setting parameters and configuring. The optional integrated arc flash protection provides new dimension to pr
