Lightning Protection Using LFA-M

A seminar about Lightning Protection Using LFA-M

Average Rating:0(Total:0)
ABSTRACT A long flashover arrester (LFA), which comprises of three flashover modules using the creeping discharge effect, is described in this paper. In this design, the total arrester stressing voltage is applied simultaneously to all of the three modules so that the voltage-time characteristics of the arresters are improved. It assured reliable protection of medium voltage (e.g., 10kv) over head power line against both induced over voltages and direct lightning strokes. A single LFA per support or pole is found to be sufficient to protect an over head line against induced over voltages. An LFA should be arranged in parallel with each insulator in order to protect a line against direct lightning strokes.
