- Abstract
At the main transformer for Helping on the 1st pre-test and found that the 1st variant of 66kV side of the A-phase winding DC resistance is too large, and the phase imbalance difference of 7.21%. On all aspects of the test wiring, testing and other parts were examined and treated, the test data did not change, the maintenance personnel to open 66kVA transformer phase "General cap" and found four phase winding A first end of the conductive rod (wiring board) connection some bolts loose, re-tighten again retest DC resistance test data qualified.
