| Abstract: | A new approach based on earth line current method is presented for on-line monitoring of XLPE power cable and an on-line insulation monitoring system is designed for XLPE power cable based on this method. This system is composed of sensors, data acquisition unit and serial interface communication based on AT89C55 MCU and MAX199ADC, and background microcomputer monitoring system This method is at low cost, easy to realize, and the system operates smoothly, safely and reliably. |
