E.S.E. Active Lightning Rod Systems

After the prohibition of radioactive lightning rods, they were replaced by E.S.E. (active) lightning rods. E.S.E. (active) lightning rods come in two types; electrostatic lightning rods and piezoelectric crystal lightning rods.

Protection is enabled by means of an active lightning rod, the tip of which is refined and sharpened in both lightning rod systems, and lightning rods are placed on the highest spot of the construction to be protected.

Lightning rods are connected with the ground along the shortest route. The protection area they provide varies depending on the location of the installation and height of such location compared to the surrounding constructions.

Electrostatic Lightning Rods

Electrostatic active lightning rods form an effective protection area against lightning. Such type of lightning rods feature different manufacturing techniques and an effective protection area.

Electrostatic lightning rods come in various types and shapes. They have several different test reports, standards (ISO and their local standards), and generally an anti-corrosion warranty of 25 years. Electrostatic lightning rods operate by using the electromagnetic field that changes/densifies in the air prior to lightning striking.

When the electr magnetic field difference between the air and ground increases, the mechanism inside the lightning rod shifts to the ionization system using this difference, and starts an ion diffusion.

Cable Tray Grounding NEMA

The following rules are for cable tray grounding rules, which is included NEMA VE2 and also applied in power plants:

* Wire or non-metallic cable trays cannot be used as a grounding conductor.

* Pull the grounding conductor through the cable tray and attach it to the tray with the screw or jaw earthing clamp shown in the figure below. This process must be repeated in each cable tray or section.
