Answer: no, they do not protect the same thing.

Often confused, the lightning arrester and the lightning rod are two elements of protection against lightning and electrical surges which do not protect exactly the same thing. Invented in 1752 by Benjamin Franklin, the lightning conductor helps protect a structure against a direct lightning strike. Often presented in the form of a point which is found on the roof of buildings, the lightning rod acts by channeling lightning towards the ground, and thus makes it possible to avoid fires. Can also be called "surge protector", the surge arrester is a device that protects electrical or electronic devices (often telecommunications lines) from transient electrical overvoltages caused by lightning or certain industrial equipment. It consists of Transil diodes, spark gaps or varistors. You too, send us your decoration question
