Lightning Protection

Benjamin Franklin perceived that lightning striking an elevation grounded rod would follow a ‘path of least resistance’ to earth. His invention advanced fire safety considerably in those days and still holds true today. The deployment of rods (now called air terminals since they are a termination point for lightning in the air) and a series of horizontal and vertical straps or wires to ground rods (so called because they are a termination point for lightning in the ground) make up the classic definition of a lightning protection system (LPS). An LPS can be defined as a ‘preferential path for lightning from intercept location to ground destination’. Lightning can be defined as ‘arbitrary, capricious, random and unpredictable’.  

Today’s buildings typically are not simple wooden or masonry structures as in the 18th Century. Modern buildings may contain structural steel; steel reinforcing in concrete; metal clad walls and/or metal roofs; cast iron waste water pipes; copper water pipes in walls; cable TV wiring; telephone wiring; electrical wiring; metal wall studs; metal door and window frames, etc.

At Northern Steeplejacks Ltd our lightning protection engineers will perform a site survey to determine the best system for your needs.

Following the initial survey and risk assessment the design, installation and testing of the system is done with minimal disruption to the client and, combined with our annual testing service, Northern Steeplejacks Ltd will be your only choice for lightning protection.

All lightning protection systems are designed, installed and tested to BS EN 62305 (2011).
