GPR Training

We also Introduce Our Associates at 

LPGI & Affiliates 

The mission of LPGI & Affiliates is to provide expert design guidance for the protection of equipment and personnel from GPR and from lightning per ASCE's Journal of Performance of Constructed Facilities and to raise the national awareness for the need for such guidance.  

 


GPR  =  A Ground Potential Rise

 = A Ground Voltage Spike

A lightning strike to any grounded structure or a high-voltage flashover from a power line to a grounded structure will cause the ground in the vicinity to rise in voltage to dangerously high levels, which can electrocute personnel standing on the ground in the area and damage or destroy electronic equipment connected to ground.

This site was created because Ground Potential Rise (GPR), caused either by lightning strike or high-voltage electrical system power faulting to ground, causes unnecessary damage to manufacturing and storage facilities with critical stores - including explosive munitions, flight operations equipment, communications towers and antennas, communications equipment, and critical electronic equipment as well as putting critical communication links and operations and maintenance personnel at risk.

Practicing what you learn here will allow your company or  organization to cut costs, remain operational even under severe lightning conditions and may save your life or the life of a coworker.
