摘要：

Long-time accelerated aging tests in a laboratory environment have been conducted on generator stator insulation to identify meaningful diagnostic measures for the assessment of degradation and the identification of aging mechanisms. A plurality of techniques are investigated and a new diagnostic parameter, the dynamic stagnation voltage, is advanced which appears to be correlated with delamination in the epoxy-mica structure. The results provide a basis for an on-line interpretation method for insulation condition.
