Below are some photos from recent lightning protection and mitigation projects undertaken by NLSI.

A mess DIN rail SPD
A mess ! Make it right the first time, please! aBarrick - PVDC May 2011 045
spd bonding straps surge protection device needs
Access to remote mine via chopper, Papua New Guinea. All inspected work is per Motorola R-56. Excellent ! (Ghana)
power quality assurance is essential for medical facilities lightning causes problems at Cayman Islands Electric Power
Attention to details is required. (E-911 Call Center, TX) Blown breaker at power plant (Michigan).
Lightning refuge designed by NLSI Typical NLSI classroom setup
Catenary LP design to Navy storage depot, Virginia. Codes compliance is essential.
Inspection and maintenance are vital to a lightning protection system Insufficient protection for stores of explosives
Control Center at mining operation. Surge protection is installed. (Dominican Republic) Costly blade replacement. Cause - lightning.
Inadequate bonding means there will be trouble ahead All metal structures do not require air terminals
D-9 Takes Direct Strike. Operator is OK. Excellent details to communications cables. (Major banking company)
Richard Kithil and Chandima Gomes Helicopter-transportable lightning shelter
Four tall masts protect a rocket launch site in Virginia. Good Salesmanship. Poor Due Dilgence.
lightning code violations Grounding solution under difficult conditions
Installing quality SPDs at all 480V panels, Chile. Investigate and Verify !
US AFB class US AFB installation errors
Investigate and Verify. Lightning-proof and vandalism-proof guard shelter (Papua New Guinea).
Mt. Haleakala protection mine site protection 2
Lightning signature at blade tip. No lightning protection is required per USAF AFI 32-1065 (Louisiana).
