Installing a lightning arrester at a site is essential to protect structures and equipment from lightning strikes. Proper installation requires a range of tools & tackles and equipment to ensure safety and effectiveness. A detailed list of tools & tackles and equipment required for the installation of lightning arrester at a site is given below:
1. Lightning Arrester(A External Lightning Protection):
The primary component of the installation is the lightning arrester itself. It comes in various types such as rod-type (Interception Rod) – Metal can be Copper Bonded, Aluminium or GI, ESE Type (Advance Lightning Protection) horn-gap, and metal oxide varistor (MOV) type. The choice depends on the specific requirements of the site.
2. Mounting Hardware(Fitting accessories for Lightning Arrester):
This includes a Mast Base Plate, brackets, clamps, U Bolt, and fasteners required to secure the lightning arrester to the structure. The type and size of mounting hardware will depend on the lightning arrester design and the structure it’s being installed on.
3. Conductor Cable (Down Conductor):
Connect the lightning arrester to the grounding system and the protected equipment using copper, aluminum, or GI conductor cables. Select the size and length of the conductor cable based on the site’s requirements and the arrester’s location.
4. Earthing (Grounding Electrode):
Grounding electrodes like ground rods or plates such as GI Gel Earthing and copper bonded Earthing are essential to establish a low-resistance path for lightning current to dissipate safely into the ground. The number and type of grounding electrodes depend on soil conditions and the site’s size.
5. Grounding Conductors(Interconnection of Earthing):
These are the cables or conductors such as GI or Copper Bonded that Interconnect to the grounding electrode(s). They should be sized appropriately to handle the high currents associated with lightning strikes.
6. Insulators:
“Use insulators to isolate the lightning arrester and conductor cable from the structure on which it’s installed. These insulators prevent electrical conduction between the lightning arrester and the structure, ensuring the safe redirection of lightning’s energy to the ground.”
7. Bonding Equipment:
“Use bonding clamps and connectors to establish proper electrical connections between various components of the lightning protection system, including the lightning arrester, conductor cables, and grounding electrodes.”
8. Hand Tools:
The installation process requires various hand tools, such as wrenches, pliers, screwdrivers, wire straightening machines, drill machines, breakers, hammers, and cable cutters. These tools are necessary for assembling and securing the components of the lightning protection system.
9. Ladders and Scaffolding:
“You may need ladders or scaffolding to safely access the installation site, depending on the height and location of the lightning arrester installation.”
10. Safety Equipment:
Safety gear is crucial to protect installers from electrical hazards and potential falls. This includes personal protective equipment (PPE) such as gloves, helmets, safety glasses, safety belt and fall protection equipment.
11. Testing Equipment:
After installation, use testing equipment like ground resistance meters and surge testers to ensure the lightning protection system functions correctly and provides the necessary protection.”
12. Lightning Risk Assessment Tools:
Tools for lightning risk assessment, such as lightning detection systems and surge protection devices, may be necessary to evaluate the site’s vulnerability to lightning strikes accurately.
13. Lightning Protection System Design Guidelines:
Detailed design plans and guidelines ensure that the lightning arrester is correctly installed and complies with safety standards and regulations.
14. Documentation and Labels:
Proper documentation of the installation process and labeling of components are necessary for maintenance, inspection, and future reference.
15. Fire Extinguishers:
As a safety precaution, fire extinguishers should be readily available at the installation site to handle any fires that may occur during installation or testing.
It’s essential to engage experienced professionals or electrical engineers who are familiar with lightning protection system design and installation to ensure the system’s effectiveness and safety. Additionally, always adhere to local building codes and regulations when installing lightning arresters at a site.
