Expert Lightning Protection Consulting
and Grounding Design
The Lightning Security Specialists

We Provide:

The world’s best and most critical expertise for the proper implementation of IEEE Standard 1692; which is a treatise for multi-purpose communications and high-voltage installations. We have found from forty one (41) years of experience that it’s far too easy to "get it wrong" in cookie-cutter applications of the tried-and-true requirements of Standard 1692, leaving expensive equipment vulnerable to costly damage and weeks off line for extensive repair.

The most important aspect in the application of Standard 1692 is that the final protection package design has to be perfectly correct in every aspect to provide failure-proof protection. One small error in proper application can make a protection design package totally useless.

We provide no products, only consulting, design, and recommendations for the best lightning protection and grounding installations for substations, electronic circuit boards, equipment components, power plants, high-voltage corridors, and broadband services for school systems.

Lightning Protection Expertise 


Protecting structures from lightning does not protect the equipment within those structures from lightning damage.  However, we design the grounding and protection for both.  

Mission: Provide professional engineering design support:

1) for the protection of equipment, structures, property, and personnel from lightning and the effects of the resulting ground potential rise (GPR). ASCE’s Journal of Performance of Constructed Facilities: "Guide for Protection of Equipment and Personnel from Lightning"

2) for lightning protection systems and grounding systems. NFPA 780 Std. for the Installation of Lightning Protection Systems 2000 Edition, and UL 96A Installation Requirements for Lightning Protection Systems

3) for the grounding of electronic equipment, industrial and commercial power per IEEE Std. 1100-2005, “Powering and Grounding Electronic Equipment”,  and IEEE Std. 142-2007, “Grounding of Industrial and Commercial Power Systems”

4) for communication services being placed into high voltage environments such as substations, power plants, or in high voltage corridors. IEEE Std. 487-2000 Recommended Practice for the Protection of Wireline Communication Facilities Serving Electric Supply Locations.

4) for communication services associated with E-911 PSAP, PCS, Radio and TV Transmission Towers. ASCE’s Journal of Performance of Constructed Facilities: "Guide for Protection of Equipment and Personnel from Lightning"

5) for structural, civil, and systems engineering;

6) and will travel to any lightning problem site at a moments notice.
