Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is 1) "Statement 1 is true and statement 2 is false."
- In a DC transmission system, there is no skin effect because direct current flows uniformly through the entire cross-section of the conductor without concentrating near the surface.
- However, statement 2 is false because corona losses are more prominent in AC transmission systems due to the periodic change in voltage polarity, leading to ionization of air around conductors.
- In DC transmission, corona losses are minimal, contributing to the higher efficiency of DC systems compared to AC systems in this regard.
