Number 1 Reason Why Surge Protection is An Integral Part of Lightning Protection

-

 Surge Protection Devices (SPDs) have become increasingly important in recent years and has got wide presence across industries. Costly electronic equipment, which is sensitive to voltage peaks on the supply, are now found in all offices and factories, including highly- sensitive data processing, telecommunication and computer networks that form the backbone of worldwide communications structures without which, no company can survive. Machines and production lines are monitored and controlled by electronic equipment programmed for specific purposes.


Why is SPD an integral part of an LPS?

Lightning protection and mains systems both deal with electricity. However, the parameters that the two handle are unique. The former focuses on incredibly high currents and swift rising impulses. On the other hand, mains power offers a consistent electricity supply. Normally, it has an alternating current at a much lower voltage and a very low frequency as well. This is so it can power the appliances in a building.

The last thing we want is an LPS that will allow currents to flow into the mains. Therefore, it’s essential to coordinate both of them in a safe way via surge protection devices.

SPDs are used for protection against surges from power lines, signal lines, feeder lines and other various line voltage surges, and can be used as class 1, 2 & 3 levels of protection.


General surge protection levels are divided into three categories – primary protections, secondary protection and board level protection.

Primary protection – this applies to power lines and data lines exposed to an outdoor environment, service entry and AC distribution panels. And these SPDs need to be installed at the input side of the service entrance.

Secondary protection – required for the protection of computer systems, inverters and sensitive equipment. These surge protection devices must be installed in the various electrical cabinets present on site.

Board level protection – This is essentially done to protect each equipment connected to a power source but cannot be effectively used alone.


It can be tempting to try to install a surge protection device yourself to save money. However, this is almost never a good idea; these systems are important enough and intricate enough that the risk of harm that can come from an improperly installed SPD is too great.

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
