Prepare for power outages caused by thunderstorms in summer
Article
Summer is thunderstorm season, so it’s important to prepare for possible faults caused by lightning. Thunderstorms can damage devices in electricity and telephone networks, especially in rural areas. The easiest and most affordable way to protect computers, entertainment electronics, and phone equipment is to unplug them during a storm. It’s also wise to disconnect antenna, telephone, and internet cables.
Most faults in the electricity network during thunderstorms are caused by strong winds that topple trees onto power lines. Lightning can also damage transformers, which convert alternating voltage up or down. As a result, thunderstorms can lead to both short and long power outages in some areas.
We prepare for thunderstorms and monitor weather forecasts around the clock.
Tips for preparation
- If you live in a detached house or rural area, consider installing a lightning conductor and surge protectors in your sockets
- To ensure uninterrupted power for a computer or other sensitive device, use a UPS system. It filters voltage disturbances and allows you to save data and safely shut down the device during an outage
- If continuous electricity is essential, consider a backup power system. For example, farms often use a generator or a tractor-powered generator
- As our customer, you can receive outage information on your mobile phone through the free Sähkövahti service. You can also check the outage situation in your area on Caruna’s fault map.
