ABB Launches Grid Monitoring Relay for Wind Turbine Power Connection to Grid
Submitted by aburr on Tue, 2014-05-13 13:22ABB introduced a new grid feeding monitoring relay for wind applications, as part of the AWEA Windpower 2014 conference and exhibition. The new low-voltage grid feeding monitoring relay CM-UFD.M33, also known as the Grid Tie Relay, is a component that protects wind turbines from unstable grid activity or faults by disconnecting the electric energy source from the grid. The relay monitors voltage and frequency in single and three phase grids and trips the coupling switch when electrical values are not within set parameters.
