If you run too much current, or too low a frequency, then
the core will saturate. This means as the current
increases, you do not get an increase in magnetic flux.
This is a bad thing, because it means you have no
inductance at that point. So if you apply a ac voltage from
a low impedance driving source to a coil that has very low
inductance, the current will be excessively high!

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
