LA is a non-linear resistor i.e. during normal condition it
offer high resistance but during abnormal condition
(abnormal voltage ) it acts as a low resistor thus allow
the heavy fault current and provide path to ground.
It is pointed one as charge resides/attracted by pointed
object and always placed at top of switchyard/building.
