Alstom Circulating Current Relay CAG 14

Product Details:

CAG14 relay is applied for high impedance restricted earth fault protection of generator, transformer, reactor and bus bars. It is also used with a follower timer for time delayed earth fault protection. Other applications include capacitor bank unbalance protection, generator inter turn fault protection etc. Features • Simple and robust construction. • High stability on external faults. • Sensitive high speed protection on internal faults. Application • Differential protection of ac machines, reactors, auto transformers and bus bars. • Balanced and restricted earth fault protection of generators and transformer windings. • Transverse differential protection of generators and parallel feeders.
