Abstract:


Background: Outdoor-working insulators could be degraded due to the changes of the environmental factors. When it degrades to certain extent, the insulating property will reduce, thus the monitor of insulators’ working condition which is of significance.

Methods: This paper, designs a faulty detecting device based on “Solar Blind” UV pulse for transformer substation insulators and put forward a multivariant nonlinear regression analysis method to find the mathematical expression between degree of faulty insulators and distance, UV pulse, environment humidity. Through the establishment of the faulty insulators test model, this paper ranks the faulty insulators levels in the form of a percentage, which makes the test result clear and direct.

Results: Experiment results show that, this mathematical relation can be the criterion of faulty insulators judgment.

Conclusion: The result can provide research methods and ideas for the on-line assessment of substation insulators’ degradation.

Keywords:

Transformer substation, insulator, degradation, on-line monitoring, UV-pulse, regression analysis.
