| Abstract: | The development of line protection in Chinese power system is reviewed from earlier protection including electromagnetic protection, mechanic electric protection and commutated protection to micro processor protection which is widely used nowadays Micro processor based protection, in which the micro processor has been developed from 8 bit, 16bit to 32 bit, meets to need of kinds of voltage level Meanwhile the trend of line protection is prospected: fiber current different, applied to optical transformer and systematic networks protection |
