Lightning Arrester or LA is a protection device that is connected to the line in parallel.In stable system LA is working as a insulator. But when surge current travel through the line then it is worked as a conductor and pass the huge current to the ground.
For transformer protection you can see LA in HV side as well as LV side. This protection is mainly for high voltage system.
