| Abstract: | Based on the analysis and application investigation of direct current system insulation supervisory device of power plant and substation of Xuzhou power supply company, some defects have been found which cannot be solved by themselves. In order to remove the fatal defects, a direct current system insulation supervisory device with microcomputer line detection is proposed, which injects small AC signal with low frequency into direct current system and tracks its change by computer technique and signal-detection technique. |
