Abstract :
Combined with an on-site trip action of heavy gas protection of a 220kv transformer, the routine and diagnostic test is done and through the analysis of the test result, the fault position is found correctly and the fault part is returned in time to the factory to do the disintegration confirmation to find out the fault reason and put forward the improvement measures of such fault.
