How do you calculate lightning protection area?

How do you calculate lightning protection area?

Down Conductors As per Base Area of Structure (s) =1+(Ab-100)/300

  1. Down Conductors As per Base Area of Structure (s) =1+(Ab-100)/300.
  2. Down Conductors As per Base Area of Structure (s) =1+(1680-100)/300.
  3. Down Conductors As per Base Area of Structure (s) =6 No’s.
  4. Down Conductors As per Perimeter of Structure (t)= P/30.

Is it a legal requirement to have lightning protection?

According to RC 35 ‘Protection of buildings against lightning strikes’, a risk control publication, it is not a legal requirement for all buildings and structures to have lightning protection. Installing a lightning protection system is not only about obeying any necessary regulations.

What are the three parts of a lightning protection system?

The parts of a lightning protection system are air terminals (lightning rods or strike termination devices), bonding conductors, ground terminals (ground or “earthing” rods, plates, or mesh), and all of the connectors and supports to complete the system.

Is lightning protection the same as surge protection?

What’s the difference between surge protection and lightning protection? Most Surge protection systems only shields sensitive electronics inside a structure while lightning protection protects against external structural damage. Our Lightning protection also helps with destructive grounding surges.

What is the range of lightning arrester?

ESE Lightning Arrester, Operating Temperature Range: -20 To 85 Deg C

Operating Temperature Range -20 to 85 Deg C
Brand Indpro Techsol
Material SS
Current Gradient Less than 5 kA
Grounding Resistance Less than 10 ohm

What is the British standard for lightning protection?

IEC/BS EN 62305-3
IEC/BS EN 62305-3 provides the requirements for the protection of a structure against physical damage, by means of a lightning protection system, and for protection against injury to living beings due to touch and step voltages, in the vicinity of an LPS.

What are the types of lightning protection systems?

The 3 types of lightning protection system

  • The lightning rod (simple rod or with triggering system)
  • The lightning rod with taut wires.
  • The lightning conductor with meshed cage (Faraday cage)

What are the four elements in a lightning protection system?

A lightning protection system consists of the following five parts: air terminals (lightning rods), conductors, ground connections (electrodes), bonding, and lightning arrestors.

What is the difference between a lightning arrester and surge absorber?

Surge arrester is used to protect the circuit or electrical equipment from high voltage transient or electrical surges. Lightning arrester works like surge arrester from outside of the conductor. They absorb the electrical surges in the transmission tower itself. Lightning rod is a pre protection device.

How many types of lightning protection systems are there?

The 3 types of lightning protection system.

What is the lightning protection zone concept?

The lightning protection zone concept allows to plan, implement and monitor protection measures. All relevant devices, installations and systems must be reliably protected to an economically reasonable extent. To this end, a building is divided in zones with different risk potentials.

Are lightning protection systems required by building codes?

Lightning protection systems for structures are typically not a requirement of national building codes, although the Standards may be adopted by the authority having jurisdiction for general construction or specific occupancies.

What are the components of complete lightning protection?

The conductor system component of complete lightning protection includes main sized cables, the structural steel of a building, and bonding or interconnection wires to internal grounded building systems.

What is the best way to equalize potential for lightning protection?

A ground loop encircling a structure interconnecting all downlead cables at their base and/or grounding electrode devices is the best way to equalize potential for an entire lightning protection system. It is always possible to have varying resistance values for grounding electrodes even on the same structure.
