Indeed, a lightning storm is the most powerful display of electrostatics in nature. In this part of Lesson 4, we will ponder two questions: What is the cause and mechanism associated with lightning strikes? How do lightning rods serve to
3.1 Lightning impulse Lightning is a result of storm, a natural phenomenon. Lightning results in surges in electrical power systems. Such surges arise from lightning strikes to or near overhead conductors. These may be classified as: • Direct strokes: when a thundercloud directly discharges onto a transmission line tower or lines.
When considering both the physical principles and observations of the earth flash lightning return stroke (LRS), the DLCRM yields results that are consistent with lightning measurements.

HISTORICAL DEVELOPMENT OF LIGHTNING PROTECTION SYSTEMS The development of the modern lightning protection system began with Benjamin Franklin. Franklin found that he could generate a 3 inch long spark when he discharged a capacitor by bringing a blunt iron bolt up to it.
Nonetheless there are several theories that make a good deal of sense and that demonstrate many concepts previously discussed in this unit of The Physics Classroom. The precursor of any lightning strike is the polarization of positive and negative charges within a storm cloud.
There were reports on failures of lightning protection systems due to several factors: insufficiently-sized conductors, conductors made of the wrong materials, metal bodies not being bonded to the lightning protection system, and an insufficient number of strike termination devices [e.g., Henley et al., 1778; Anderson, 1879].
