HV Exit Exam • Set 4 Question 6 of 30

Power loss due to corona discharge on an overhead transmission line is directly proportional to:

✓

Direct Answer

Option B: Supply frequency (f + 25)

According to Peek's formula for corona loss, power loss P is proportional to (f + 25), where f is the system supply frequency.

All Options

Radius of conductor

Supply frequency (f + 25) (Correct Answer)

Spacing between conductors

Dielectric constant of air

Detailed Explanation & Context

According to Peek's formula for corona loss, power loss P is proportional to (f + 25), where f is the system supply frequency.
