In order to reduce the effect of natural lightening so that the transformer can be saved from the very high voltage and current caused by the lightning, a device or u can say a protective device is connected in parallel with the incoming terminals of the transformer which bypasses all the fault current and voltage of the lightning is called lightning arrestor
