With the progress of transformer technique, weight of transformer is increased, the rated voltage is raised and the capacity is enlarged, which puts up higher requirement on field installation and test, especial-ly on partial discharge test. The paper introduces typical structure of oversize transformer and gives equipment configuration for field partial discharge test; it analyzes detection and validation of transformer failure and demonstrates that the test equipment is feasible in field partial discharge test of oversize transformers.
