Question
Download Solution PDFWhich of the following statements is/are true regarding AC distribution system and DC distribution system?
a) In DC distribution system, the voltage drop is due to resistance only.
b) In AC distribution system, the voltage drop is due to resistance only.
c) In AC distribution system, the effect of inductance is always neglected.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option A.
AC distribution system
- The AC transmission system is used for short-distance transmission.
- It uses three conductors for transmission.
- The voltage drop is due to both resistance and inductance.
- Presence of skin effect, voltage surge, and interference with the communication line.
- Repairing and maintenance are easy and inexpensive.
DC distribution system
- The DC transmission system is used for long-distance transmission (in form of HVDC).
- It uses two conductors for transmission.
- The voltage drop is due to resistance only.
- The effect of inductance is always neglected.
- Absence of skin effect, voltage surge, and interference with the communication line.
- Repairing and maintenance are difficult and expensive.
