Protection of power station generators
Generator Protections are broadly classified into three types: Class A, B and C. Class A covers all electrical protections for faults within the generating unit in which generator field breaker, generator breaker and turbine should be tripped. . For generators smaller kVA, the than IJD52 2000 may be sub-stituted. The IJD52 is also used on class 3STD16C. Use with 87T. with 21 and 51V. For two step tripping with external fault 51TN, 51V or 21X would first trip breaker short time delay, control device 86G. A 210 MW turbo-generator which includes an alternator, a steam turbine, a boiler and other auxiliaries costs more than hundred crores in Indian rupees. The generator also represents the most complicated unit demanding an extensive. . H. Schweitzer, III (Editors), Modern Solutions for Protection, Control, and Monitoring of Electric Power Systems.
