How Does a Surge Suppressor Work to Protect Against Power Surges and Line Noise?
A standard Surge Suppressor passes the electrical current along from the outlet to a number of electrical and electronic devices plugged into the power strip. If the voltage from the outlet surges—rises above the accepted level—the Surge Suppressor diverts the extra electricity to ground through the outlet’s ground wire. In order to channel the excess energy of a surge from connected equipment, a Surge Suppressor requires connection to a properly wired and grounded AC outlet. Running a Surge Suppressor from an ungrounded outlet prevents the Surge Suppressor from doing its job. Most Surge Suppressors include a “LINE OK” or “PROTECTED” diagnostic LED that will alert you to potential grounding problems. Most Surge Suppressors include special noise filters that remove line noise. The amount of filtration is indicated in the technical specifications for each unit. Noise suppression is stated as Decibel level (Db) at a specific frequency (KHz or MHz). The higher the Db, the greater the prote
