English Dictionary

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

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。

意味（1）

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.

The Ferranti effect is much more pronounced in underground cables, even in short lengths, because of their high capacitance.
