Lightning Surge Protection

Transient over-voltages – an introduction

Lightning Surge protection benefits from technological innovation which increasingly places electrical and electronic equipment at the heart of our everyday lives. From satellite communications and sophisticated computer technology to power generation from environmentally sustainable sources, modern electrical and electronic systems are a fundamental part of today's business activities, yet these critical systems are at risk from the multiple daily occurrences of transient over-voltage.

What are transient over-voltages?

Transient over-voltages are high magnitude voltage peaks of only micro-seconds duration, also known as surges. Direct and indirect lightning strikes are their most common source, but they may also be created by the switching of large inductive or capacitive loads within buildings.

What are the risks from transient over-voltages?

Transient over-voltages cause damage to electrical and electronic systems and equipment, leading to the disruption of operational and sometimes even critical services, and resulting in expensive down time and repair costs. Measured against the potential losses to business operations or essential services, the need for protection against transient over-voltages becomes clear.

Surge Protection under BS EN 62305

BS EN 62305 requires that surge protection must be included as part of a lightning protection system, to safeguard the building, and the people and equipment within it, from the damaging effects of transient over-voltages.
