← ScienceWhich outcome regarding power factor arises when connecting significantly long underground insulated power cables?
A)Leading power factor reduces energy loss
B)Reactive current causes increased losses✓
C)Harmonics injection distorts voltage waveform
D)Surge impedance loading limits reactance
💡 Explanation
Increased reactive current results in increased losses because substantial cable capacitance causes charging current to shift the power factor. Elevated reactance, not surge impedance loading, is responsible; therefore, the reactive current is the loss factor, rather than leading power benefitting.
