2.3.9 Installation of Lightning Protectors

Overview
A lightning protector is a device to be installed on an outside line to prevent a dangerous surge
from entering the building and damaging equipment.
A dangerous surge can occur if a telephone line comes in contact with a power line. Trouble
due to lightning surges has been showing a steady increase with the development of electronic
equipment.
In many countries, there are regulations requiring the installation of a lightning protector. A
lightning strike to a telephone cable which is 10 m (33 feet) above ground can be as high as
200,000 V.
This system should be installed with lightning protectors. In addition, grounding (connection
to earth ground) is very important for the protection of the system.
