Annual Lightning Maintenance Programme

Lightning is the most commonly feared naturally occurring phenomenon. It has an amazingly destructive force. The safety of any structure and its components exposed to an electrical storm is wholly dependent on a correctly designed, manufactured and installed lightning protection system.

Unitech adopts a six-step lightning maintenance program:

  1. LIGHTNING PROTECTION SYSTEM ANALYSIS
  2. LIGHTNING RISK ASSESSMENT ANALYSIS
  3. SURGE PROTECTION INVESTIGATION WORKS
  4. EARTH RESISTANCE TESTING & DATA COLLECTION
  5. UPDATING OF ALL LIGHTNING ENGINEERING DRAWINGS
  6. REPORTS, RECOMMENDATIONS AND COMPLIANCE

6 Steps Lightning Maintenance Program

 

1. LIGHTNING PROTECTION SYSTEM ANALYSIS

Our top priority in any lightning audit works would be to fully understand the existing lightning protection system in place at customer’s site and its adequacy, strength and weaknesses with regard to SS 555 Part 1 – 4: 2010 lightning protection standard. This analysis include all existing earth termination network, structural lightning protection, equipment and electrical earthing and static discharge applications.

2. LIGHTNING RISK ASSESSMENT ANALYSIS

We conduct a lightning risk assessment of customer’s premises and evaluate its tolerable risk limit based on SS 555 Part 2 recommendations which facilitates the selection of appropriate measures to be adopted to reduce the risk of loss of human live, physical damage and failure of electrical and electronic systems.

3. SURGE PROTECTION INVESTIGATION WORKS

We investigate the causes of any damage to equipments, structures and sensitive electronics equipment with regard to the secondary effects of lightning and determine the adequacy of any existing surge protection installation on site.

4. EARTH RESISTANCE TESTING & DATA COLLECTION

Upon completion of our lightning protection system and risk analysis, our engineers proceed to site to test the mechanical and electrical integrtiy of all lightning protection system components and earth resistance readings during our data collection process.

5. UPDATING OF ALL LIGHTNING ENGINEERING DRAWINGS

Once all site works are completed, we implement the updating of new or existing AutoCAD drawings for the complete lightning and earthing systems on site indicating all earth points, air termination networks and bonding points where applicable.

6. REPORTS, RECOMMENDATIONS AND COMPLIANCE

All our lightning audit and rectification works are incorporated into a hard and soft copy report with recommendations for improvements on any deficiencies found and upon completion of all rectified works, a certificate of lightning compliance would be issued by our Professional Engineer.

Want to know more?

 

Our team of expert engineers undertake detailed inspection and testing of existing earthing and lightning protection systems. Following the test, in addition to your test certificate, you will also receive a comprehensive report on the condition of the system with our recommendations for repairs or upgrades where necessary to restore it to a compliant condition.
