(COMPREHENSIVE LIGHTNING PROTECTION PRODUCTS)

External Lightning Protection System is designed to protect a structure from damage due to lightning strikes by intercepting such strikes and safely passing their extreme high currents to ground. Since it is not possible to predict the lightning strikes, it is advisable to take adequate protection against lightning strikes.

Lightning causes major risk to modern electronic systems including computers, data communication networks, CCTV equipment, plant sensors, programmable logic controllers(PLCs), even uninterruptible power supplies (UPSs). To protect the inside electronic systems from lightning currents and transients over voltages, surge protection is needed.

We offer comprehensive Lightning Protection Solution ensuring effective external & internal protection.

The complete system will include conductors, strike termination rods, ground terminals and inter-connecting bonding to minimize side-flashing and surge protection device to prevent harmful electrical surges in power, data and communication lines.

Once a lightning protection system is installed, regular maintenance and periodic safety checks are required to ensure it continues to work at its optimum level.

We provide total solution taking account of all potential risk from lightning.

• Complete range of Type tested LPS components as per IEC 62561(62305).
• Sequentially type tested: Ageing, (10/350µs)100kA Lightning impulse, Mechanical test.
• Effective protection against lightning and switching transients-Offering wide range of SPDs: Power, Signal, Instrumentation, Ethernet, and Telecom lines.
• The external lightning protection system intercepts, conducts and disperses a direct lightning strike safely to earth ensuring effective external protection.

THE ESSENTIAL PARTS OF A LIGHTNING PROTECTION SYSTEM

Air terminals to intercept lightning flash. (i.e., create a preferred point of strike)

Down conductor To Conduct the lightning current to earth.

Earthing system to dissipate current into the earth.

Equipotential Bonding To make an equipotential bond to prevent dangerous potential differences between LPS, structure and internal elements/equipment.

AIR TERMINALS

Air-terminations are those items specifically placed to capture the lightning strikes. Permitted air-terminations are

• Vertical Rods (including masts)
• Mesh conductors
• Catenary wires
• Natural components

Air-terminations are placed in accordance with the selected design method to provide protection to the structure.

All air terminations shall be interconnected and shall be connected to down-conductors. Mesh and air-termination interconnections should be provided with expansion joints wherever required.

Down-conductors are used to provide the interconnection between the air terminations and the earthing termination to carry the lightning current.

The reliable performance of the lightning protection system is entirely dependent on an effective earthing system to dissipate the energy. Hence, the earthing system shall be designed to meet the following:

• Provide a low impedance path to dissipate the energy.
• Minimize the touch and step potential hazards.
• Long term performance of the system particularly when used in inaccessible areas like basement.

Even though the LPS earthing system is installed and tested as a dedicated system, it is required by the standard IS /IEC 62305 that the lightning protection earthing system is to be interconnected with other earthing systems. Isolation from the telecommunication, power and other earthing systems is not recommended.

Equipotential Bonding is required to protect against dangerous sparking between the LPS components and the structure or internal system, where the isolation by adherence to separation distance requirements cannot be maintained.

The important areas to be considered are:

• External services entering into the structure (telephone, power lines, water, gas, etc.)
• External metallic items entering the structure (cable ducts, pipe work, etc.)
• Metallic items on or in the structure (handrails, elevator rails, pipes, ventilation ducts, etc.)
• Internal electrical and electronic circuits and systems.
