Lightning Surge protection helps protect terminal damage to electrical and electronic equipment at the heart of our everyday lives from a power surge.

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 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 disruption of operational and critical services, and resulting in costly down time and repair costs. Measured against the potential losses to business 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.
