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.
MRG3P & MRG1P
Relay for control of voltage asymmetry, phase failure, phase sequence and min. and max. voltage level in 3-phase applications. Device has internal timer for delay reaction.
MRF1P
Monitoring relay for voltage network frequency control with adjustable maximum and minimum zone level and internal adjustable timer for delayed action and reconnection.
