In a world where technology plays an integral role in the daily operations of our facilities, the need for reliable, resilient, and safe electrical systems is paramount. Lightning strikes pose a significant threat to the infrastructure, electrical equipment, and human life within all types of facilities including:

  • Data centres
  • Pharmaceuticals
  • Hospitals / Primary Care Sites
  • Schools /Colleges / Universities
  • Government Buildings
  • County Councils Offices
  • Heritage sites

To ensure the safety of personnel against loss of life and protect valuable assets, it is crucial for your facilities to have their lightning protection, earthing systems and surge protection devices tested and maintained regularly so that these systems comply with the current safety standards.

Regular maintenance checks by certified specialist technical engineers allow any potential problems to be identified early before they become an issue, that could cause potential harm, loss of human life, or damage to the facility like a data centre, where critical information is stored.

This article by our testing and maintenance engineers explores the reasons behind this practice and outlines the key aspects that LPI Group carry out as part of an inspection.

1. Ensuring Safety

The main reason for the annual testing and maintenance of lightning protection systems, earthing systems, and surge protection devices is to ensure the safety of personnel and occupants within a facility.

Lightning strikes can cause devastating consequences, such as electrical shock hazards, fires, and at worst, loss of life. By conducting regular inspections, potential hazards and deficiencies can be identified and rectified in a timely manner, mitigating the risk of accidents.

2. Protecting Infrastructure and Equipment

Damage, degradation, or disruption of electrical and electronic systems within a structure is a distinct possibility in the event of a lightning strike.

Lightning strikes can induce power surges that can damage or destroy sensitive devices, leading to costly downtime and repairs.

Environmental conditions can also affect your systems such as corrosion.

Annual testing and maintenance of surge protection devices help ensure their proper functioning, providing an added layer of defence against power surges caused by lightning strikes or other electrical disturbances.

3. Compliance with Standards and Codes

Many industries and regions have specific regulations and codes in place that mandate regular inspections of lightning protection systems, earthing systems, and surge protection devices. Adhering to regulations and standards is recommended as most insurance companies require certification.

LPI Group’s testing and maintenance engineers carry out inspections in line with EN 62305, UNE 1186, and NFC 17 102 Standards.

Once a test and maintenance check has been completed by the LPI engineers, a detailed report is generated that outlines evidence of compliance with relevant standards. This is then issued to clients, which can be crucial during audits or inspections by regulatory bodies.

 

4. Identifying Deficiencies and Expanding Lifespan

Regular inspections allow LPI engineers to identify deficiencies, weaknesses, or damage in lightning protection systems, earthing systems, and surge protection devices. These deficiencies may include corroded conductors, loose & corroded connections, damaged grounding electrodes, outdated surge protection devices, or degradation due to environmental factors.

Annual inspections will increase the lifespan of lightning, earthing, and surge protection systems to protect against premature replacements.

When Does My Facility Require an Inspection?

 

There are certain factors that can determine when your facility will require a test and inspection of the lightning, earthing, and surge protection system.

  1. Geographical Location

If a data centre or other facility is in an area with high lightning activity, more frequent inspections may be required to protect the critical data housed inside.

  1. Age of Equipment and Infrastructure

Older equipment and infrastructure may be more susceptible to lightning-related damage, requiring more frequent inspections.

  1. Compliance Regulations

Industry compliance regulations may require regular inspections and testing of lightning protection and earthing systems.

  1. Type and Level of Lightning Protection and Earthing System

The type and level of protection systems installed in the data centre may also determine how often inspections should be conducted.

Key Aspects of an Inspection

During an annual inspection of lightning protection systems, earthing systems, and surge protection devices, several key aspects are examined by LPI Group.

1. Site Assessment

LPI Group may perform a site assessment to identify any vulnerable areas of the facility and determine the lightning activity in the area.

2. Risk Assessment

LPI may perform a risk assessment to help identify potential lightning strikes and their impact on the facility. LPI’s specialist technical design and engineering teams will then develop measures to control or eliminate the risks identified.

3. Visual Inspection

For levels of protection, I and II, should be completed annually, while III to IV should be every 2 years.

Lightning protection systems utilised in applications involving structures with a risk of explosion should be visually inspected every 6 months.

This involves examining the overall condition of lightning protection components, earthing electrodes, bonding conductors, and surge protection devices for signs of damage, corrosion, or wear.

4. Continuity and Resistance Testing

Conducting tests to ensure the integrity of grounding connections, bonding conductors, and lightning protection system components.

This includes measuring the resistance of grounding electrodes and verifying the continuity of conductors.

5. Surge Protection Device Testing

Surge protection devices are visually inspected by LPI engineers.

6. Documentation and Reporting

Prepare documentation of inspection findings, including any deficiencies or recommendations for repairs or upgrades. This documentation helps create a historical record and serves as a reference for future inspections.

Regular maintenance schedules and on-site surveys can contribute to effective lightning protection and earthing in data centre facilities. This is done by ensuring these systems are functioning effectively and are up to date with the latest safety standards.

7. Conduct Periodic Inspections and Maintenance

LPI Group may conduct periodic inspections and maintenance on your facility to ensure that the lightning protection and earthing systems are functioning correctly. Inspections also ensure systems meet the current industry standards and regulations.

By conducting regular inspections and maintenance, potential problems can be identified early before they become big issues that could potentially cause harm or damage.
