What if you could install lightning-free automation? Well, now you can. Wireless automation has changed the paradigm associated with lightning damage to oilfield automation equipment.

Background

Historically, oil & gas automation has relied heavily on the direct burial of cable for signal communication from remote devices back to a central controller. This cable acts as a copper conductor for power transients (indirect lightning strikes). A majority of all automation damage is caused by indirect lightning strikes. Copper cable buried on a location acts like an antenna picking up all inducted power surges from the surrounding area.
