本应用指南适用于额定用于并联电抗器切换的交流高压（>1000 V）断路器。本应用指南提供了并联电抗器切换的理论背景，以及如何使用从测试结果中获得的信息来预测现场过电压，并给出了如何缓解这些过电压的建议。

This application guide applies to ac high-voltage (> 1000 V) circuit breakers rated for shunt reactor switching. This application guide provides the theoretical background of shunt reactor switching and how information obtained from test results should be used to predict overvoltages in the field, and gives suggestions how to mitigate these overvoltages.
