To prevent these problems, it is important to take certain precautions and protect the most sensitive appliances from possible overloads.
During a thunderstorm, surges can damage electrical appliances connected to the mains. Lightning striking the electricity system can generate overloads, affect the operation of devices and in some cases render them completely useless.
To avoid damage, specialists recommend unplugging certain electrical appliances when there is a risk of thunderstorms.
1. Televisions
Televisions are vulnerable to electric shocks, as their internal systems can be affected by a sudden change in voltage. An overload can burn out the main board and damage the screen, making repair costly or even impossible.
To minimize the risks:
- Turn off and disconnect the TV from the power supply before the storm begins.
- Use a surge protector to prevent damage in case of sudden power outages.
- Do not use the TV during lightning strikes or power fluctuations.
2. Computers
Computers and laptops contain sensitive circuits that can be damaged by a sudden power surge. In addition, a power surge can affect the hard disk and cause loss of important data.
To protect them:
- If you need to use it, do so with a battery backup (UPS) that regulates power.
- Save important files before the storm to avoid loss due to unexpected power outages.
- Turn off and disconnect your computer from the mains and internet.
3. microwaves
Microwaves have sensitive electronic components that can be burned by an electric shock. Moreover, as it is a high consumption device, an overload can affect the internal fuse or transformer and render it inoperable.
To avoid damage:
- Unplug the microwave during heavy thunderstorms.
- Use a voltage stabilizer to reduce the effects of electrical fluctuations.
- Do not use the microwave during lightning strikes or intermittent power outages.
How to protect appliances during a storm
- Use surge protectors on the plugs of sensitive devices.
- Avoid using multiple plugs in the same unprotected outlet.
- Unplug sensitive devices at the first sign of a storm.
- Wait a few minutes before reconnecting devices after a power outage.
