Analysis of the Partial Discharge in Generator Based on Sk-Ku Plot
For evaluating the partial discharge extent of generator
as far as the two dimensional phase resolved plots were concerned
a new type of plot
namely Sk-Ku plot
was constructed.Furthermore
the Sk-Ku plot was put into the cross analysis of partial discharge detected from two practical generators.The results analysis demonstrate that
Sk-Ku plot can effectively reflect the partial discharge extent and partial discharge derived from different generators can be compared to some extent.Sk-Ku plots of discharge magnitude and count take on the character of conic
what is more
with the increase of partial discharge
the Sk-Ku plots show the trend of shifting from 1
2 quadrants to 3
4 quadrants.In addition
the distribution range of the data decreases significantly.
