How does an electrical surge suppressor protect electronic devices?
1 Answer
An electrical surge suppressor, also known as a surge protector or surge suppressor, is a device designed to protect electronic devices from voltage spikes and electrical surges. These surges can occur due to various reasons, such as lightning strikes, power grid fluctuations, or switching of electrical devices.
Here's how an electrical surge suppressor works to protect electronic devices:
Diverting excessive voltage: Surge suppressors are equipped with metal oxide varistors (MOVs) or gas discharge tubes. These components have a high resistance when the voltage is within a normal range. However, when a surge occurs, the voltage across these components increases, causing them to conduct electricity and divert the excess voltage away from the connected devices.
Clamping voltage: The surge suppressor has a clamping voltage rating. When the voltage exceeds this threshold, the suppressor activates and begins to redirect the excess voltage. The clamping voltage rating is typically set to a level that is safe for most electronic devices, ensuring they are protected from dangerously high voltage levels.
Absorption of energy: When a surge happens, the surge suppressor absorbs and dissipates the excess electrical energy as heat. This prevents the surplus voltage from reaching the connected devices and damaging their sensitive components.
Multiple outlets: Surge suppressors usually offer multiple outlets, allowing you to connect several electronic devices to a single surge protector. This means all the connected devices are protected from surges simultaneously.
Indicator lights: Many surge suppressors have indicator lights to show if the device is functioning correctly. Some models include a "protected" light to indicate that the surge suppressor is operational and capable of safeguarding connected devices.
It is essential to note that electrical surge suppressors have a limited lifespan and can wear out over time, especially if they experience repeated surges. To ensure continuous protection, it's recommended to replace surge suppressors periodically or if they have experienced a significant surge event. Additionally, while surge suppressors can protect against voltage spikes, they may not safeguard against other types of power issues like brownouts or complete power outages, for which other solutions like uninterruptible power supplies (UPS) might be necessary.
