Ferranti effect

名詞

An increase in voltage occurring at the receiving end of a long transmission line, above the voltage at the sending end. This occurs when the line is energized, but there is a very light load or the load is disconnected. The capacitive line charging current produces a voltage drop across the line inductance that is in-phase with the sending end voltages considering the line resistance as negligible.

日本語の意味

長距離送電線の受電側で、送電側よりも高い電圧が現れる現象 / 負荷が非常に軽い、または切断された場合に起こり、送電線の容量性充電電流が、送電側の電圧を上回る電圧上昇を引き起こす現象

このボタンはなに？

When the circuit breaker opened and the long line carried almost no load, engineers observed a pronounced Ferranti effect that raised the receiving-end voltage above the sending-end voltage.

遮断器が開いて長い送電線にほとんど負荷がかからなかったとき、技術者たちは受電側の電圧が送電側を上回る現象（フェラッティ効果）を確認した。
