Application and Development of BIT Technology in Aeronautical Eletrical Power System

Great importance is increasingly attached to Built in test (BIT) technology used in aeronautical electrical power system. This paper introduces the BIT technology and its four parts, as detection technology, signal processing technology, fault identification & diagnosis technology, and fault processing technology. It is elaborated that in abroad, the BIT technology used in aeronautical electrical power system has been going through four generations and has become digital and standard. This paper points out that the kernel of the BIT technology is fault diagnosis, and suggests that we should pay more attention to the BIT technology, especially the fault diagnosis technology.
