Abstract: Introduction was made to the key technology of large transformer load test and the principle of capacitance compensation. Taking a 500 kV one-phase duplex winding converter transformer for example, this paper analyzed how to carry out the converter transformer load temperature-rise test under the condition of site limited power capacity in converter transformer station from aspects of test connection, device parameters selection, compensation capacity calculation and test procedure etc. This paper proposed to solve the kind of problem of insufficient test power capacity by using the existing alternating current filter in converter transformer to change the capacitance wiring mode. It has good engineering practice guiding significance.
Key words: converter transformer; load test; filter; compensation
