Lightning conductor E.S.E. TESLA-S


TESLA-S® E.S.E. lightning conductor - Principle of operation

The TESLA-S® lightning head carries a sharp pointed rod, made from special bronze alloy to attract and capture lightning. This rod incorporates a safety arc gap for the main lightning current and is attached to a sphere shape casing. A metal horizontal disc is fitted symmetrically around the casing, making electrical contact with it and the rod. The disc will react to the bad weather electric field and will be charged inductively with the field rise.
A special high-tension converter is located inside the sphere shape casing. High tension is achieved by the natural instability and negative resistance of a plasma arc placed inside a transverse magnetic field produced by a coil. The circuit is characterized by a series connection of an arc’s negative resistance to an inductance and capacitance. A very high ionizing tension is produced at the area around the head’s rod. The TESLA-S® type is powered by the induction of the bad weather thunder field itself, a phenomenon that typically lasts a few to several minutes of an hour.
The head of the TESLA-S® is equipped with a safety arrangement to protect its own circuitry during a lightning capture. The internal gap mechanism, the sparking device and the circuitry are placed in a waterproof and enforced sphere shape casing. The sphere shape of the casing allows the lightning current to pass freely through the grounding cathode. Additionally the casing’s base acts like an external spark gap between the head and the cathode.
