PDF Type SA-1 Generator Differential Relay - ABB A differential protection relay is defined as the relay that operates when the phase difference of two or more identical electrical quantities exceeds a predetermined amount. The "Generator differential protection" function detects short circuits in generators, and also ground faults in generators with a grounded neutral point (typical for low voltage). One will receive all the electrical protection relay trip signals, and denoted as86-1. In this case 400kV CT is connected as winding 1, 21kV CT from the generator neutral point as winding two and two 11kV CTs as winding 3. Our customers include leading original equipment manufacturers and end users of their products.
