WebA lightning arrester, also known as a lightning isolator, is a device used on electric power transmission and telecommunication systems to protect the system’s insulation and conductors from the damaging effects of lightning. This has a high-voltage terminal and a ground terminal. Many people search for “Arrester Lightning” nothing wrong ... WebLightning Arresters The principle is that once the voltage surge travels across the conductor and reaches the place where it is to be installed. So it will break the insulation of the conductor for a moment so that the voltage surge can be discharged toward the ground. Web19.1.1 During a switch closure • Switching surges may develop during a closing operation just before the contacts are able to make. It may occur at a stage when the gap (i.e. the dielectric) between the contacts becomes incapable of withstanding the impressed voltage and breaks down. jesus christ cartoon image
