Abstract
The basic functions of Siemens LSA7 microprocessor-based protection devices for generator-transformer bank are presented. The configuration of LSA7 protection devices for high rating generator-transformer bank are put forward. At the same time, the principles of Siemens LSA7 protection series such as differential protection, field-loss protection, stator one point grounding fault protection and rotor one point grounding fault protection are analyzed in detail.关键词
