原文是这样的：However, the HR-based method fails to prevent false tripping of relays because high second-harmonic components during internal faults and low second-harmonic components are generated during magnetizing inrush for transformers having modern core material .
句子中出现了high second-harmonic components 和low second-harmonic components ，请问这两个词在专业学科的中文词汇中的准确意思是什么？真的是高二次谐波分量和低二次谐波分量吗？两个分量有什么分别？谢谢~

high是指二次谐波含量高，low是指其含量低传统的变压器（现在应该仍然广泛使用）在内部故障时二次谐波分量较少，而变压器励磁涌流中二次谐波分量较高。随着制造工艺改进，励磁涌流中二次谐波分量减少，而变压器内部故障时二次谐波分量增加。
