Protecting electronics from storms: Essential steps to prevent damage

Securing electronic devices during a storm is crucial to prevent damage. Most people remember to unplug devices from the power outlets, but that’s not the end of potential sources of risk.

Which electrical devices should be unplugged during a storm? Usually, we focus on home entertainment equipment, computers, and gaming consoles. These are expensive devices and are commonly considered sensitive to power surges. Discussions on this topic are popular, and while many consider unplugging electronics as excessive caution, there is evidence that it is an effective form of protection.

When we unplug devices during a storm, it’s usually enough to turn off the power strip or pull the plug directly from the socket. However, we must not forget about other cables connected to the devices.

Simply turning off the power may not be sufficient for televisions. These devices are often connected to at least one additional cable, such as an antenna cable, which can pose the greatest risk.

Antennas, both satellite and those for receiving terrestrial television can contribute to costly damage. A lightning strike to the antenna can destroy the TV via the antenna cable. That’s why it is essential to remember to unplug the television not only from the power cable but also from the antenna cable during a storm.

Sony takes electronics protection a step further. In their published guide, recommendations include disconnecting the television from the network and antenna, as well as from the internet cable and HDMI. During atmospheric discharges, devices such as decoders or routers can transmit high voltage to the TV ports, leading to damage.

Reaction speed is critical in all this. Once a storm starts in earnest, the risk of equipment damage increases. In this case, storm apps can be helpful, providing warnings about approaching atmospheric discharges. Monitor Burz, Blitzortung Lightning Monitor, and Windy are the three most reliable options.
