V/X connection traction transformers is mainly used in high-speed railway or passenger dedicated line currently. But on-site induced overvoltage withstand test and partial discharge（PD）test methods for such special transformers are rarely reported. Combined with national standards and power industry standard

this paper analyzes and discusses the standards

procedures

the methods of applied voltage and measurement of on-site PD test for handing over and taking over of 220 kV V/X connection traction transformers used in high-speed railway or passenger dedicated line

proposes the suggestions for on-site test of this kind of transformer

and calculates the parameters of the test. On-site tests for all the transformers of six traction substation are carried out. The results show that the test method is reasonable and feasible

and the testing process and results meet the requirements of the standard. On the other hand

this test method solves practical problems of on-site induced overvoltage withstand test and PD test of this kind transformer

which provides certain practical and reference for developing onsite PD test of this type transformer.
