Lightning protection at home

Induced lightning is actually very familiar to us

Lightning strikes 1 km away can destroy electrical products

What is induced lightning (YUDO-RAI)?

Sometimes lightning strikes nearby can cause electrical products to break down. This is caused by what is called "induced lightning".

Induced lightning refers to the large voltage and current that is generated in power lines, telephone lines, antennas, etc. in the vicinity when lightning strikes. When induced lightning travels through power lines and enters buildings, it can damage electrical products.

The influence of induced lightning is widespread, and if you hear thunder rumbling nearby, there is a danger of induced lightning.

Example of damage caused by induced lightning

I heard thunder last night, but…

In most cases, damage from induced lightning is seen at first glance as just a malfunction. Even if there is no damage on the outside, the induced lightning may have damaged the components inside the equipment.

  • The phone stopped working.
  • The air conditioner stopped working.
  • The Internet is disconnected.
  • Hot water stopped flowing from the water heater

There are many ways for lightning to enter a building

There are four main routes of entry for lightning.

These are the four main paths through which lightning can enter a home. Appropriate lightning arresters can be installed for each of these paths to protect equipment.

  1. Power lines (power outlets, etc.)
  2. Communication lines (telephone lines, cable TV, Internet lines, etc.)
  3. Antenna (TV antenna, etc.)
  4. Ground wire (e.g., ground wire)
