Wireless automation has changed the paradigm associated with lightning damage to oilfield automation. Historically, oil and gas automation has relied heavily on the direct burial of copper cable for signal communication from remote devices back to a central controller. This cable acts as a copper conductor for power transients, such as indirect lightning strikes. Most automation damage is caused by these indirect lightning strikes. Copper cable buried on a location acts like an antenna picking up inducted power surges from the surrounding area.
