Complete protection for feeders and motors Comprehensive selection of protection functions for distribution network overhead lines, cable feeders and motors. Ultra-fast arc protection The unique integrated arc fault functionality adds a new dimension to the total safety of the installation and the reliability of the protection and control system. Interface a maximum of 6 point sensors or 1 fibre loop and 4 point sensors to extend the protection scheme to a new dimension with 2 ms tripping time. Total control Extensive bay control functionality including local and remote control of 6 objects and status supervision of another 2 objects. Easy-to-use ON – OFF buttons for select – execute control of circuit breaker. Comprehensive measurements A range of measurement functions including phase and residual currents, residual, line or phase voltage, frequency, current imbalance, maximum demand, negative phase sequence current, active and reactive power and energy according to the primary connection. Power quality analysis Power quality analysis includes supervision of harmonics up to the 15th order, THD of currents and voltage as well as voltage sag and swell. Full recording features Following a fault, the relays provide upto 2000 event sequence recordings, fault value registration and disturbance recordings. Programmable protection stages Including overcurrent, overvoltage, undervoltage, earth fault and frequency protection. Extensive communication A large number of supported communication protocols are included: IEC 60870-5-101, IEC 60870-5-103, Modbus TCP, Modbus RTU, Profibus DP, TCP/IP, SPA-bus slave, DNP 3.0 and IEC 61850. User-friendly configuration The free of charge VAMPSET software simplifies configuration, commissioning and operation and ensures the protection and control needs of users are easily achieved.
