Lightning Protection Products – Everything You Need To Know

-

Lightning strikes can cause a fire, explosion, chemical release or mechanical disruptions within or around your facility.

At LEC, we know that all these risks must be considered and protected against when developing a lightning protection system. With over four decades of experience, our support and expertise have assisted thousands of businesses, both large and small, to achieve effective protection against lightning.

Our LPS are engineered with advanced technology and consist of the same four key components – air terminals, conductor/bonding, grounding, and transient/surge protection.

Air terminals – by LEC is based on the point discharge principle or charge transfer. It provides thousands of points with specific point separation, which simultaneously produce ions over a large area, thus preventing the formation of a streamer, which is a precursor of a lightning strike. Our patented Dissipation Array system prevents strikes by continually lowering the voltage differential between the ground and the charged cloud to below lightning potentials, even in the midst of a worst-case storm. Other products include Spline Ball Ionizer (SBI) for areas with low wind profiles, Spline Ball Terminal (SBT) to reduce the risk of direct strikes, and Streamer Delaying Air Terminal (SDAT) to delay upward streamer generation. 

However, we also consider secondary lightning strikes and transient currents while designing a lightning protection system.

Conductors/bondings – These are required to create a low-impedance grounding system by using chemically charged electrodes to neutralize any stray voltage that may have entered the facility. Our lightning protection products include chem-Rod a low-impedance chemical grounding electrode that solves problems found with conventional grounding rods, LECWELD metal is an easy and efficient field welding system, and Grounding Augmentation Fill (GAF) is specially formulated to help create a low-resistance earth interface, and Smart Ground Testing Service includes computer modeling with a complete professional analysis to IEEE/IEC standards and practical recommendations.

Transient/surge protection – This is required to protect against transients traveling through data lines and another conductive path. Products include FG300K, FG225K Facility Guard, FGB220K, and TLX130K, which are high-performance UL 1449 Listed Type 1 SPD under our lightning protection products umbrella. Other products include Data Line Protector (DLP), Coaxial Line Protector (CLP), and LEC TE-POE-A.

The Importance Of Maintaining A Lightning Rod Protection System

-
Lightning rods must undergo periodic inspections and maintenance, as indicated by national and international regulations. These periodic inspections allow the detection of deviation from reference standards or anomalies in the installations caused by environmental conditions such as corrosion, incorrect handling or expansion of the building where the lighting rod protection is installed.  Maintenance of an effective lightning rod protection system is essential due to the following: -    Efficiently dissipate heavy fault currents and electrical surges, both in magnitude and duration, to protect equipment being damaged so as to minimize downtime, service interruptions and replacement costs -    Provide a stable reference for electrical and RF circuits at the installation to minimize noise during normal operations -    Protection of personnel who work within the area from dangerous electrical shocks For a lightning rod protection system to work optimally, each and every part needs to be i

Lightning Protection Products You Never Knew You Needed

Dissipation Systems are designed to prevent lightning strikes. These refer to devices using point discharge phenomena to retard and reduce the potential of lightning strikes on their protected devices. Choosing the appropriate lightning protection products for a specific application requires several performance issues to be considered, such as the radius of the dissipater electrode cross-section, the construction material of the dissipater, the number and density of electrodes, and the configuration of the dissipater on the structure it is designed to protect.  The Dissipation Array System (or DAS) is a lightning prevention system. Well, it doesn’t prevent lightning from happening altogether, but it does prevent lightning from striking the protected structure. There is a lot of detail on how it does this, but the simple version is that it lowers the electrostatic field in the protected zone. This prevents upward-rising lightning leaders (or streamers) from being created on the pro

  We are Pioneers in: ·          Lightning Protection System ·          Chemical Earthing Installations ·          Lightning Surge Protection Devices Let’s talk about our patented lightning surge protection devices . The term surge protection device (SPD) describes electrical devices typically installed in power distribution panels, process control systems, communications systems, and other heavy-duty industrial systems, for protection against electrical surges and spikes, including those caused by lightning.  When clean, uninterrupted power is crucial, LEC’s next-generation surge protection devices are ready to provide the highest level of performance for the safety and reliability of your electrical systems. These devices are able to accomplish two tasks for protection, i.e., surge voltage in terms of amplitude needs to be limited and discharge of the surge voltage to the ground, which is done without causing any damage to the devices.  Lightning Surge Protection Devic
