A strong breakthrough with the introduction of a new lightning protection method that demonstrates scientific thinking and is safer for residential buildings is lightning collector early discharge (controlled early discharge).<\/span><\/p>\n

\u2022 In an electrostatic field, the sphere (lightning rod) is grounded through an impedance and, due to its geometry, the corona effect is minimized.<\/span>
\n\u2022 In the electromotive case, the descending lightning conductor is capacitively coupled to the sphere surface.<\/span>
\n\u2022 The sphere responds to the increase in electric field by increasing the voltage due to the long-time constant created by the high-impedance static channel<\/span>
\n\u2022 The sphere responds to the increase in electric field by increasing the voltage due to the long-time constant created by the high-impedance static channel<\/span>
\n\u2022 Accumulated energy is released in the form of ions, creating an upward-leading path that actively conducts lightning<\/span><\/p>\n

The position of the ionization path that allows the lightning to pass through is defined as the position where the ascending leader comes into contact with the first descending leader from the cloud. The stronger the upward current (upward lead ray) from the lightning needle to the cloud, the faster it will meet the descending leader, and the chance of these two rays coming into contact before other currents discharge from nearby high points is bigger. The starting point of the first ascending leading ray determines the point of impact of lightning on the ground. The lightning conductor that emits the lead early will create optimal conditions for the formation of the discharge current. This is the unique and improved feature of the Lightning Collector Needle Frontray Emitter over traditional passive classical lines.\u00a0<\/span><\/p>\n

Nowadays, the manufacture of lightning receivers to be able to have complete features is always an area of research for manufacturers. But if we keep applying classical technologies without introducing new devices, can there be improvement in science? Is it advisable to renew the classic Lightning receiver device?<\/span><\/p>","protected":false},"excerpt":{"rendered":"
