Line Voltage Information
If the facility is located in an area where power lines are subject to frequent
lightning strikes, verify with the electric company that the building transformer
is equipped with surge protectors. These, as well as a "crowbar" type of
protection, can be installed at the main service entrance if the building
transformer is not equipped with lightning protection.
While lightning is one cause of power line transients, others can be internal or
external to the building environment. The general application of transient surge
suppression is low-cost insurance to ensure long life of the equipment being
installed.
