| Abstract: | The design and realization of an on-line monitoring system for over-voltage including lighting impulse over-voltage and inner over-voltage of a 10 kV distribution network are described. The performance of the resistance-capacitor voltage divider for over-voltage signal acquisition is analyzed as are the coaxial line, the trigger, the signal processing, the data acquisition and its control and waveform analysis software in the system. The monitoring results show that the system is satisfactory in providing scientific support for fault analysis of power systems. |
