Moisture accelerates degradation of electric insulators, claims new study
Moisture in the atmosphere can expedite degradation of insulators that protect the long conductor or wires which transmit electricity from place to place, a study has found. The study was conducted by researchers from the Indian Institute of Science, Bangalore.
Current carrying conductors, like the wires that supply electricity to our homes, experience partial arcs or corona discharges near the vicinity of high voltage conductors. Corona discharges, as they are called, appear as blue light in the air surrounding the medium, and may also produce some sound.
