The world's largest class 8,880MVA short circuit generator

The world's largest class 8,880 MVA and 1,603 MVA short circuit generators have been manufactured, commissioned and are working successfully. The 8,880 MVA generator, the largest capacity in the world, is for TOSHIBA High Power Laboratory, and the 1,603 MVA generator is for the High Power Testing Laboratory of LG Industrial Systems Co., Ltd of Korea. These generators are power sources for testing of circuit breakers, and can be operated at both 50 and 60 Hz. This paper describes the specification, design concept, key technologies and field test results of these short circuit generators.
