Causes of humming sound in a transmission line (below 220 KV) other than corona effect
(OP)
A humming sound (louder, not normal, & as if house-hold meter abnormal sound) heard near one of the 132 kV Transmission line tower, after its operation since 6 years. The transmission line Conductor used is Cardinall with Current Load - max 70 MW. The louder humming sound seems increased from past week, disturbing the nearby resident.
The other arm of the tower hold the other circuit (recently stringed) and currently not energised.
I suppose the effect is not a corona, please suggest what might be the alarming situation to the Power supply system and to the residents nearyby ?
