Which outcome occurs when a long three-phase transmission line's open circuit voltage significantly exceeds the sending end voltage?

💡 Explanation

When a long transmission line is open circuited, the Ferranti effect occurs because line capacitance charges with minimal reactance, causing voltage to rise at the receiving end. Therefore, a voltage rise results, rather than an increase in line impedance, radio interference or a reduced current capacity that would need other triggering factors.
