초록

We have done the insulation diagnostic test of generators in domestic five power plants since 1987 and tested A.C. current increasing rate($\Delta$I), $\Delta$tan$\delta$ and partial discharge in generator winding insulation. This study is described the correlation between nondestructive result(A.C. current increasing rate, $\Delta$tan$\delta$ and partial discharge) and lapse of time in generators.
