Electrical Engineering MCQ Question on Power Transmission and Distribution Engineering.
Charging current in the transmission line is:
- Introduced due to imperfection of dielectric
- Associated with capacitance of transmission line
- Dependent on voltage and frequency
- All of above
Correct answer: 4. All of above
Charging current in the transmission line is associated with capacitance of transmission lines. The charging current actually happens due to imperfection of dielectric, if there was perfect dielectric present around conductors no charging current will be introduced.
The charging current of the transmission line depends on voltage, as well as on the frequency of the transmission line.
