Surge protection devices (SPDs) work to safeguard your electronics by protecting them against sudden and unwanted power surges. For many electronic devices, even a tiny spike in voltage can damage them and become a safety hazard.
What Can Cause a Power Surge?
A power surge can occur when something triggers electricity to flow back into the system, or when the flow of electricity is interrupted and restarted. This could be caused in several ways, including lightning strikes, electrical overloading, faulty wiring, and restoration of power after an outage.
A power surge could be as little as 5 or 10 volts from an additional outlet being turned on, or thousands of volts from a lightning strike. Luckily, power surges caused by lightning strikes are rare. But when they do occur, the large power surge will cause instantaneous damage, “frying” circuits and melting plastic and metal parts.
More commonly though are low-level surges, which can still be damaging. These may not melt physical parts or blow any fuses, but instead they can prompt “electronic rust,” which gradually degrades the internal circuitry eventually leading to complete failure of the outlet.
Most homes have multiple items which are susceptible to power surges. Any devices containing a microprocessor are particularly vulnerable to irreparable power surge damage. These small digital components are so sensitive. Even a small fluctuation can damage their functioning.
How SPDs Can Help
An SPD will help prevent damage to electrical devices as they limit any voltage surges that may arise within the electrical system. They provide point-of-use protection against current spikes and overvoltage by diverting surging current and limiting any surplus of voltage to a level that will not damage the protected device or appliance.
SPDs encompass surge suppressors and surge arrestors. The suppressor works to protect outlets from spikes in voltage, by blocking or shorting to ground the incoming current. Whilst arrestors protect from external occurrences that may cause over voltage transients. Essentially an SPD can help by safeguarding your device or appliance.
