该单相电路用于测试真空断路器的电流斩波和重燃。 该电路代表一个由真空断路器断开的变压器。连接到真空断路器的供电侧由母线的Ln和Cn和电缆连接在一起表示。 Ln = 5mH，Cn = 100nF。(This single phase circuit is used to test current chopping and reignition of vacuum circuit breaker. The circuit is representing a　transformer that is switched off by the vacuum breaker.The supply side connected to the vacuum breaker is represented by the Ln and Cn of the busbar and cable connection together. Ln=5 mH, Cn=100 nF.)
