Question 1 of 10
What is the Ferranti effect?
The Ferranti effect describes the phenomenon where the receiving end voltage exceeds the sending end voltage under light load conditions.
Question 2 of 10
Which of the following is a primary cause of the Ferranti effect?
The capacitance of the transmission line leads to a charging current that causes the voltage rise at the receiving end.
Question 3 of 10
In which type of transmission line is the Ferranti effect most prominent?
Long transmission lines have a higher capacitance, leading to a more pronounced Ferranti effect.
Question 4 of 10
What component in a transmission line primarily generates reactive power causing the Ferranti effect?
The capacitance of the transmission line acts as a source of reactive power.
Question 5 of 10
What is the relationship between the charging current and the length of the transmission line?
Longer transmission lines have higher capacitance and therefore draw more charging current.
Question 6 of 10
Under what load conditions does the Ferranti effect primarily occur?
The Ferranti effect is most noticeable when the line is lightly loaded or unloaded.
Question 7 of 10
How is the Ferranti effect typically mitigated?
Shunt reactors are used to absorb the reactive power generated by the line capacitance.
Question 8 of 10
What is the main consequence of the Ferranti effect?
The primary effect is an increase in the voltage at the receiving end of the transmission line.
Question 9 of 10
Who is credited with discovering the Ferranti effect?
Sebastian Ziani de Ferranti observed the effect in the London power system.
Question 10 of 10
What is the impact of supply frequency on the Ferranti effect?
Higher supply frequency increases the capacitive reactance and thus the Ferranti Effect.
