Which of the following devices will receive voltage surge first traveling on the transmission line?

  • Lightning arresters are the devices that will receive voltage surge first traveling on the transmission line.
  • Voltage surges or transient overvoltages are high-voltage fluctuations that occur on the power system due to lightning strikes, switching operations, or faults.
  • These surges can cause significant damage to the power system equipment, particularly to the insulation of the transformers and cables.
  • To protect the power system equipment from these surges, lightning arresters are installed at strategic locations on the transmission line.
  • A lightning arrester is a protective device that conducts the surge current to the earth and limits the voltage surge to a safe level.
