Every Vaisala outdoor system has a capable two-stage transient protection in all external signal cables (leaving the site) and power connection cables. Local sensors with short cables may rely on the built-in protection on the signal interfaces.

Surge protection devices (SPD) cannot protect equipment against direct lightning strikes. They protect cables by neutralizing voltage surges that are caused by inductive or resistive (ground potential variations) coupling from nearby lightning strikes.
