E.S.E. Lightning Arrestor

We offer E.S.E. lightning arrestor, which protects structures such as high rise buildings from damage by intercepting flashes of lightning and transmitting their current to the ground. These arrestors are offer value to client owing to their good performance in toughest conditions. The E.S.E. lightening arrestors are made from best quality material that assure not only safety and improved performance. We offer lightening arrestors at industry leading prices and within very less lead time. We are engaged in manufacturing and supplying of lightning arrestor made of supreme quality raw material.

Principle of operation: The function of the lightning rods consists of emitting an ascending electrical unloading to influence the effect of the descendant tracer.

The range of Lighting Protection Systems offered by us have high efficiency and drastically reduce the risk associated with lightning. We manufacture our products with the use of alloy of high quality that are acquired from trusted vendors of the market.

Features

The Early Streamer Emission air terminal offered by JMV is a non-electronic system. The absence of electronic makes it extremely reliable and easy to install on a very large variety of sites. In addition, the materials used to make Air Terminal have been selected for their resistance to both corrosion and very high temperatures.

An Early Streamer Emission air terminal is designed to reduce the average statistic time associated with streamer emission. An ESE Air Terminal presents a gain in early streamer emission time compared to a Simple Rod device, placed in the same conditions. The gain is evaluated in a high voltage laboratory.

The ESE Air Terminal has been extensively tested at an independent high voltage laboratory in accordance with the requirements of French NF C 17-102

Installation

Illustration of JMV Lightning Protection System This illustration is not drawn to scale nor does it portray an actual or typical application. It is designed to illustrate some of the major components of the JMV Lightning Protection System and their relationship with one another.

Working Principle

The air terminal is a device for lightning protection with a spherical metal part fixed to the top. This sphere is insulated from the rod by a ring made from a material with very high electrical insulation properties. When a storm comes, the external electrode (sphere) charges under the influence of the electric field until the potential reaches a critical value from which a spark appears between the exterior electrode and the tip of the central electrode. The tip enables plasma to be created close by the tip. The plasma, in association with the intense electric field created close by the tip, constitutes the first stage of development of an upward leader. The spark produced at the top of the air terminal will initiate the advance of the discharge, engendering an upward leader moving in the direction of the downward leader.

	FIRST PHASE  The voltage between the cloud and the ground increases until an ionized path is created emanating from the cloud. That ionized path travels in leaps towards the earth.		SECOND PHASE  The extremity of the leader has the same potential as the cloud. As the leader nears the earth, the atmospheric potential increases above the ground and the air terminal is electrically charged.
	THIRD PHASE  When the extremity of the leader arrives at a critical position, the air terminal reaches its maximum electrical charge, and the streamer emission of the accumulated current is produced on its extremity which ionizes the air around the summit.		FOURTH PHASE  The electrical arc, generated at the tip of the air terminal, provokes a streamer emission which rises toward the leader more quickly than on a simple rod (it is the early streamer emission).
	FIFTH PHASE  The link between the earth and the cloud is formed and the lightning current passes along the ionized path.		SIXTH PHASE  Several electrical discharges can rapidly follow the first one.
	SEVENTH PHASE  The voltages between the cloud and ground are equalized and electrical discharges cease.
