Monitoring relays
Digital monitoring relays for industrial and domestic applications are designed with attention to reliability, preciseness, measurement accuracy and long working life. Monitoring relays have implemented DFT (Discreet Fourier Transformation), which separates disturbances, events and high harmonic influence from fundamental measured signal. Thanks to DFT, values for further calculation are more precise and reaction more accurate.
