Lightning Surge Protection Devices For Every Mission-Critical Industry

-

 

Lightning surge protection devices are an indispensable part of lightning protection for electronic equipment. Its function is to limit the instantaneous overvoltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or to discharge powerful excess lightning current into the ground.

The most reoccurring cause of surge is lightning. During a lightning storm, it may strike somewhere near a power source and affect the voltage running through it. When a lightning surge hits an electrical system, it damages the devices connected to it, resulting in a loss of efficiency.

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.



LEC provides an entire product line of lightning surge protection devices, like:

·         Facility guard for industrial service entrance and subpanel applications

·         The DC surge protector for protection of all DC applications to ensure maximum lightning safety

·         Data line protectors for low voltage telecom and control lines

·         Coaxial line protectors for protection of all types of coaxial line applications including antennas, microwaves, broadband, cellular systems, and GPS equipment

SPDs are classified according to their standards into three different types:

Type1 – this can discharge partial lightning currents and commonly employs spark gap technology. They are generally installed in the service entrance switchboard to protect low-voltage equipment from direct lightning strike overvoltage.

Type2 – this version can help prevent the spread of over-voltages in electrical installations and help protect connected equipment. They are fitted to all distribution panels that serve electrical equipment. They offer protection against the residual effects of lightning strikes and switching overvoltages.

Type3 – This are only required to be installed as a supplement to type2 and has a low discharge capacity. It's best suited for a location close to the protected equipment to further protect against switching transients generated within a facility.

Lightning surge protection devices are applied extensively on various industries, especially for those critical-mission industries. If you are interested in any of the applications get connected with our Lightning Eliminator team.

Lightning Surge Protection Devices For Data Centers

-

Very little commercial or administrative activity can occur if the computers are out of action. So, every minute of data center downtime can severely affect a firm’s profitability and reputation. Lightning surge protection devices can help ensure that frequent but unpredictable events such as lightning strikes and power surges do not cause data loss or severe and lasting damage to sensitive data center equipment. Data centers must have high systems availability with a maximum of four minutes of downtime per year, which can only be achieved with the redundancy of power supply from the energy distributor. They usually have two medium-voltage sources to reduce the risk of power failure, one of which serves as a backup. A third source, in the form of generators, is often found on site along with an uninterruptable power supply to ensure power supply maintenance even in the event of a fault. UPS also serves to safeguard the quality of electrical energy. However, due to their low residu...

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...

6 Reasons To Opt For A Comprehensive Lightning Protection Design System

Since 1971, LEC has developed specialized expertise in lightning protection design. While traditional lightning strike protection methods may be adequate for some installations, custom lightning protection design systems meet more exacting requirements when more complete protection is needed. Engineering an appropriate solution is more complex than simply putting up a lightning rod. Before implementing a protection plan, each site is evaluated for risk factors, geography, soil type, and many other parameters. A comprehensive lightning protection design is a necessity for all facilities, and here are six reasons: Climate change has increased the number of lightning strikes each year, putting every part of the country at risk.  The devices that operate your facility and keep you, your investment, and your personnel safe — including security systems, heating and cooling equipment, and electronic appliances — can be knocked out by lightning surges, even if the lightning does not direc...
