Auckland_Sky_Tower_Lightning_Protection.pngWhile there is no known lightning prevention method, there are plenty of suitable options to protect your facility from the damage of a strike. Lightning protection systems help to control the passage of lightning and discharge it to minimize risk, injury, fire or equipment downtime. 

Though, lightning protection systems are not one size fits all. It’s important to consider the height, architecture and type of structure to determine if an alternative to a conventional method is necessary.

The ERICO SYSTEM 3000 is an advanced lightning protection system that is specially integrated. The unique design includes an air terminal, downconductor, lightning event counter, and low impedance grounding system that work together to form a holistic protection system. 

The ERICO SYSTEM 3000 is a practical alternative when conventional methods may not be suitable, such as unconventional building facades, contemporary architecture, or structure height. In these cases, a conventional system would not offer suitable protection from a devastating lightning strike. 

Read below to learn how the ERICO SYSTEM 3000 has helped safeguard structures around the world from lightning.

How New Zealand’s Sky Tower Survived 16 Lightning Strikes

One of Auckland, New Zealand’s greatest attractions is the Sky Tower. Hovering over the skyline at 328 meters tall, tourists flock to the location for breathtaking 360-degree views of the city. 

Tourists aren’t the only thing the Sky Tower attracts; due to its height, it’s also susceptible to fierce lightning strikes. On July 21, 1999, over a 30-minute span, the Sky Tower was hit with approximately 16 lightning strikes.

While you may expect the result to be catastrophic, the ERICO DYNASPHERE was responsible for capturing and safely diverting all 16 strikes. In live video footage, the ERICO DYNASPHERE launches a continuous upward leader to intercept the strike.

The ERICO SYSTEM 3000 Continues to Strike Against Lightning

Besides the Sky Tower, cases of the ERICO SYSTEM 3000 capturing and preventing a catastrophic lightning event have been documented across the world. Some scenarios include:

  • The Bank of China in Hong Kong was protected by more than 100 direct strikes since it installed the ERICO SYSTEM 3000 in 1989.
  • In West Java, Indonesia, the ERICO SYSTEM 3000 saved the Mt. Tangkuban Perahu Communications Tower from the 56 lightning strikes over three years.
  • The Centerpoint Tower in Sydney sustained more than 40 strikes of lightning without damage or downtime.
  • Since installation, the ERICO SYSTEM 3000 protected Hong Kong’s Central Plaza from more than 20 lightning strikes.

Through stories like these and its use in modern lightning protection research, the ERICO SYSTEM 3000 has served as a building block for the latest protection advancements.
