- The large-scale power transformer is one of the key equipment for power grid, and its quality has important effects on the security, stability and economic operation of the power grid. It is a good method to strengthen the quality control for sampling test. But it is difficult to carry out for large power transformer, because of the restriction of testing condition demanding. The development of test system, test items and sampling objects determination principle are introduced. The sampling test process and results evaluation standard for larger power transformer of State Grid Corporation of China are also introduced. The sampling effects are analyzed by means of game theory. The sampling test results are analyzed in multiple dimensions, such as qualified rate, voltage grade, type, supplier coverage, and trend. The quality problems and sampling test effects are mainly analyzed. The results of no-load loss, load loss, partial discharge test and sound level measurement. The sampling qualified rate of power transformer increased from 84% in 2009 to both 100% in 2011-2013. Finally, the sampling mode innovation is studied on the basis of summarizing the experience of sampling test, and the suggestions are put forward
