What is it about?
Polymer insulators find increasing applications in the transmission and distribution lines. Their lightning impulse voltage characteristics play an important role in insulation coordination and their flashover mechanism is governed by streamer phenomenon. This articles gives the streamer characteristics in polymer suspension insulators.

Why is it important?
The streamer inception location, propagation path and influence of corona ring on lightning impulse flashover voltage and path were studied. A method to compute the flashover voltage is presented with experimental validation
Perspectives
I hope this article would be helpful to compute the lightning impulse voltage of polymer suspension insulators without doing any time taking high voltage testings.
