  • Monitoring The Insulator Condition By On-Line Voltage Distribution Measurement
    2008 International Conference on Condition Monitoring and Diagnosis, Beijing, China, April 21-24, 2008

    Detection and monitoring the insulator condition usualy start by doing a visual detection using daycor to detect defect on the insulator that cause corona. If there is defect or pollution on the insulator surface, corona usually can be detected. Cleaning will be able to minimize the corona if it is caused by pollution. When defects are there in particular internal defect, cleaning will not give any help. The only way is replacing the defected insulator.
