Application

The GPU2000R is a Generator Protection Unit in the proven line of 2000R series relays. The 589T series is designed to provide primary and/or backup protection for small to medium size generators, and the 589V/589W series are suitable for synchronous generators of any size. Utilizing three advanced microprocessors, the GPU2000R provides multifunction protection, expansive fault and operations records, detailed metering, programmable inputs and outputs, and advanced communications options. These new series units also provide improved performance compared to the earlier 589R series: The sensitivity of the reverse power anti-motoring element is now down to 0.2% of rated machine power; the loss-of-excitation function is now accomplished by a mho-circle impedance element.
