For preventing the fault of inter-turn insulation of air core reactor

in this paper

the inter-turn insulation detection method of air core reactor is summarized and analyzed. The analysis is made from such aspects as the fault cause

on-line detection and off-line detection of the reactor to judge operation condition of the reactor. The trial test for the inter-turn insulation of dry type air core is performed at site by the high frequency pulse oscillation method recommended in China national standard GB1094.6-2011

and 3 units of equipment are found to have defects in inter-turn insulation. The result of this test has a definite accuracy

but the inter-turn insulation detection for reactor with the high frequency pulse oscillation method is continuously and deeply explored.
