Lightning Surge Protection Devices Is The Best Defence Against Lightning

-

With every upgrade in technology, sensitive systems like dynamic positioning, drilling instrumentation and control, and other rig management systems essential to staying online are becoming more vulnerable. From the standpoint of electronics, the secondary effects of lightning — earth current transients and atmospheric transients, ground potential rise, and electromagnetic pulse — are a greater problem than the direct lightning strike. In some cases, the damage caused by lightning may not show up immediately after a storm but sometime later.

What is surge?

Cloud-to-ground lightning bolts are a common phenomenon—about 100 strike Earth's surface every single second—yet their power is extraordinary. Each bolt can contain up to one billion volts of electricity. Peak current intensity is of the order of 10 to 100 million volts of electricity, with an average of about 30,000 amps. Energy goes into light and heat with temperatures about 54,000 degrees Fahrenheit, six times hotter than the sun. When this power surge comes in contact with power lines, facilities, the earth, or other assets, tremendous damage may occur.

A Lightning surge protection device is an appliance or device designed to protect electrical devices from voltage spikes. An SPD attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages above a safe threshold.

The terms lightning surge protection device (SPD) and transient voltage surge suppressor (TVSS) are used to describe electrical devices typically installed in power distribution panels, process control systems, communications systems, and other heavy-duty industrial systems for the purpose of protecting against electrical surges and spikes, caused by lightning.

LEC provides an entire product line of lightning surge protection devices. Facility Guard provides UL-listed lightning surge protection for industrial service entrance and subpanel applications. The UL-listed Transient Limiters provide up to 100,000 voltage amps and lightning surge protection per phase. The DC Surge Protector provides protection for all DC applications to ensure maximum lightning safety. Other products provide similar lightning surge protection for Data Lines, Telcom, Coax, and Control Lines.

Our lightning surge protection devices have excellent designs that offer more outlets at comparable prices. They offer peace of mind to everyone concerned about sudden power spikes that could hamper their business and destroy expensive electronics.

This is one of the best investments against unlikely events like a lightning strike. Take action now!

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...
