Surge protection devices: your best defence
Every day, lightning strikes homes and properties 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 valuable possessions.
Destruction of electronics
A power surge can enter your house either via a direct strike, or indirectly. Direct strikes occur when lightning passes directly through a building, often causing major damage and fires. Indirect strikes occur when lightning strikes ground nearby, or power lines directly connected to a house. When this happens, any connected appliance or electronic device can be destroyed.
• High replacement costs of electronics and circuitry
• Disruption of your personal and/or professional connectivity
Protecting your equipment with surge protection devices
A lightning strike near a building or overhead supply lines suddenly increases the voltage from 230 V to 3 or 6 kV. The resulting surge, which lasts a few microseconds, can destroy electronic components such as memory, processors, capacitors, and screens.
An SPD can damp the spike down to a value compatible with that which most connected appliances can withstand: approximately 1.5 kV. All devices within 10 meters of the switchboard are effectively protected. If your devices are more than 10 meters away from the installed SPD, additional protection needs to be added, such as a type 3 SPD in a nearby switchboard of a power strip with integrated surge protection.
