Technical Background Supporting Removal of the Lightning Ground Wire on TallTowers
Extensive testing and analysis conducted by NRG Systems, Inc and Lightning Technologies, Inc. concluded the NRG 60m XHD TallTower structural members and guy wires alone provide sufficient protection for the electronics and wiring against direct attachment lightning strikes to permit removal of the down-tower copper conductor. This write-up substantiates the removal of the down-tower copper conductor on all NRG XHD TallTowers.
The removal of the down-tower copper conductor does not impact the electrostatic discharge (ESD) protection of the electronics (sensors and Symphonie logger). No change has been made to the grounding system electronics, so their ESD protection is unaffected by removal of the down-tower conductor.
