摘要：
For an electrical machine built with classical enameled copper wire, turn-to-turn capacitance variations can be used as an indicator of the insulation layer aging if it is correlated with standard indicators such as breakdown voltage or cumulative probability of failure at rated voltage. Such capacitance variations have a significant effect on the high frequency behavior of the machine winding which can be measured with the appropriate monitoring system.
