ABSTRACT: Brazil Belomonte Transmission I Project is China's successful bidder in the first ultra-high voltage transmission project, but also for the first time in China to assume a single 12 pulse type of ultra-high valve type test, the test is extremely difficult. The paper introduces the dielectric type test of the converter valve in the Belomonte I Project, and puts forward a new test method for the protection of the test equipment and avoid the influence of the spurious parameters on the test. The circuit topology and test results for the project will be presented.
