HV Exit Exam • Set 5 Question 22 of 30

Which of the following is an undesirable consequence of corona discharge on power transmission lines?

✓

Direct Answer

Option D: All of the above

Corona discharge wastes energy through I²R-equivalent power loss, generates high-frequency radio noise (RFI), and produces ozone/nitric acid that corrodes metallic fittings.

All Options

Generation of radio and television interference

Loss of electrical energy (power loss)

Production of ozone leading to conductor corrosion

All of the above (Correct Answer)

Detailed Explanation & Context

Corona discharge wastes energy through I²R-equivalent power loss, generates high-frequency radio noise (RFI), and produces ozone/nitric acid that corrodes metallic fittings.

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • High Voltage Safety Officer & Switchgear Operations (HV).
