Effective Lightning Protection Design System For Outdoor And Indoor Substations

-

Direct lightning strikes to transmission lines or substations may damage the electrical equipment and threaten any nearby personnel. 

More over a lightning strike on a transformer can cause a major explosion due to the amount of extra voltage injected into it. Lightning bolts can contain up to 120 million volts – depending on the length and size. When a transformer blows, it can knock out power for hundreds to thousands of people. In addition, collateral damages can occur because any line connected with the blown transformer, is now live and could be carrying thousands of volts. Blown transformers can also set its surroundings on fire, especially in dry environments.

Because substations should operate reliably and because they are susceptible to lightning strikes, it is common practice to provide a Lightning Protection Design System for both outdoor and indoor substations.

LEC lightning protection is based on some very basic principles:

  • Don’t attract lightning, eliminate it
  • If some secondary currents pass through a protected structures, to ground them safely to earth, thereby reducing the risk of side flashes
  • To protect equipment from surge and transient on power lines, signals and data lines.
  • Provide excellent pre-sales and after-sales services
  • Mitigate loss or damage to all expensive and important electrical and electronic components
  • Minimize financial loss and downtime

Substation lightning protection design systems must protect substations (plant equipment and buildings) from harmful effects of direct lightning strikes and from thermal, mechanical and electrical effects caused by lightning discharges.

Substations can be completely protected against lightning damage. Lightning Eliminators & Consultants, Inc (LEC) is committed to providing lightning protection products, solutions and services by utilizing innovative patented charge transfer technology, grounding systems engineering, surge protection design, and providing comprehensive consulting services based on physics and state of the art engineering principles. The design of an LPS for substations is specific to the requirements of the substations and related cost considerations. However, the best protection measures are best understood through a thorough risk assessment.

LEC provides the only No Strike Warranty in the industry on our DAS solutions. When installed, maintained and supervised by LEC, our DAS prevents direct strikes with a 99% success rate, minimizing the risks to substations and its operations.

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
