Comprehensive measurements
A range of measurement functions including phase and residual currents, residual or 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 relay provides 200 event sequence recordings, fault value registration and disturbance recordings.
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.
Extensive communication
A large number of supported communication protocols are included in VAMP 40: IEC 60870-5-101, IEC 60870-5-103, Modbus TCP, Modbus RTU, Profibus DP, TCP/IP, SPA-bus, DNP 3.0 and IEC 61850.
User-friendly
The free of charge VAMPSET software makes configuration, commissioning and operation user-friendly and ensures the protection and control needs of users are easily achieved. A wide auxiliary power supply, 19-265 V ac/dc, 50/60 makes this relay suitable for every kind of installation.
