HVDC test is one of routine tests on the convertertransformer.
高压直流试验是换流变压器的例行试验之一。

Based on the mathematical model, we adopted topological description series and the technique of fault equivalence disposal to calculate all kinds of faults of the new convertertransformer.
基于所建立的数学模型，采用拓扑描述串和故障等效处理技术来计算新型换流变压器的各种故障。
