Lightning and Electrical Surge Protection

REQUEST A CALLBACK

Electrical surge protection minimises the risk of damage from lightning strikes, voltage and power surges and transient voltages by blocking or redirecting unwanted surge current to earth.

Remark Group are an experienced lightning protection and maintenance specialist, covering the whole of the UK. We are experts in our field, installing lightning protection systems that comply with the industry-recognised safety standards.

We offer survey, design, installation, testing, maintenance and repair solutions for earthing, lightning protection, surge protection and height safety.

Did you know?

  • Every day there are about 8 million lightning strikes globally.
  • The tallest structure is the most likely point of contact in a lightning strike.
  • Isolated structures on large expanses of flat land are likely to attract lightning strikes.
  • While some structures are more likely to attract a strike, lightning is 100% unpredictable.

Depending on your needs, our expert design team can provide either a standard or bespoke solution. We can also offer layout drawings to meet architect, consultant and contract engineer specifications.

Once a lightning protection system is installed, it must be professionally tested at least once a year to ensure it is capable of conducting a potential lightning strike to a safe earthing point. This ensures compliance with the Electricity at Work Act 1989, BS6651 and BS EN 62305.

Surge Protection

Electrical Surge Protection Risk Assessment

Every day, lightning strikes buildings somewhere in the world. Any structure in the path of an electrical storm is at risk. While only lasting for a few microseconds, lightning causes a dangerous voltage surge that can destroy your electronic devices. Installing surge protection devices, SPDs, can reduce or even prevent damage to your electronic devices

A surge or lightning protection device prevents damage to electrical equipment from over-voltage transient events by blocking or redirecting surge current to the ground instead of passing through the equipment.

Surge protection is connected to a conductor on the line side of equipment. The protection is also connected to ground and functions by routing energy from an over-voltage transient to ground if one occurs, while isolating the conductor from ground at normal operating voltages. A varistor is usually adopted to achieve this, as its resistance is variable for different voltage levels.

Frequently Asked Questions

What is lightning and surge protection?

A surge or lightning protection device prevents damage to electrical equipment from over-voltage transient events by blocking or redirecting surge current to the ground instead of passing through the equipment.

Is there a legal requirement for 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. However, the Electricity at Work Regulations 1989 do apply to most businesses. This means that adherence to BS EN/IEC 62305 for the installation of LP systems is compulsory.

How often should lightning protection be tested?

It is imperative that all lightning protection systems are inspected and tested at least once a year.
