Surge Protection


Meter Based Surge Arrester Program


From computers to microwaves and high-tech entertainment centers, the average home has a huge investment in electronic equipment. AC (alternating current) surges are not caused by lightning only. Utility work, adverse weather conditions, or even something as simple as electric motor activity within a building (air conditioners, elevators, copiers, printers and refrigerators, for instance) can cause power fluctuations. Surge protectors extend the lifetime of sensitive electronic equipment by protecting it against harmful power surges and overvoltage problems.

Meter based surge arresters add the advantage of buffering electronic equipment from everyday fluctuations. This is critical, as "invisible" power disturbances have a cumulative effect, and can lead to premature failure of all or part of an unprotected electronic system.

Klickitat PUD recommends that to protect these sensitive electronics, the best offense is a two-step defense: 

External Surge ProtectionMeter based surge arresters help stop external power problems before they can enter the home. Transient voltage can enter a home through the main power, telephone and television service entrances. In addition, transient voltage can also enter a home through: electric fences, electronic dog fences, electric driveway gates and intercoms, closed circuit video systems, air conditioners, any antennas mounted on a home, pool pumps/filters, outdoor speakers, etc. Any electronic equipment that is wired to a home's main electrical panel is a potential avenue for transient voltage to enter or exit. 

Internal Surge ProtectionWhile the meter based surge arrester is an extremely effective tool to protect a home from transient voltage, Klickitat PUD highly recommends using "point of use" surge protectors inside a home to further protect electrical equipment from the damaging effects of transient voltage. As mentioned above, transient voltage can enter a home a multitude of ways, so if by chance the transient voltage enters from a point other than the main service entrance, using point of use surge protectors will give you peace of mind that you are protecting your electrical equipment to the best of your ability. When looking for this type of product we recommend the UL1449 standard. Call for more details.

KPUD Meter based Surge Arresters:

  • Can be installed on a residence with a 200 amp metered service or smaller.
  • A monthly fee of $4.50 will be added to your utility bill once installed.
  • Power will be off to the home for approximately 30 minutes for the installation.
  • Lead-time of approximately two weeks from time of request
  • Surge arresters cannot be installed if your house is not grounded or you have either a CT meter or a 400 amp service.
  • A list of covered appliances, electronics computer & office equipment, tool and other items is attached.
  • Warranty: up to $5,000 per item, but not to exceed an aggregate of $50,000 per failure. Warranty information is attached for your review. Exclusions apply. 

Customer Responsibility - Once the arrester is installed, remember to periodically check the two red indicator lights on the surge arrester to make sure they stay lit. If one or both of these lights are not lit, this means the device is either not working properly or it took a hit and protected your home. If the lights are not lit, contact our Energy Services Department at (509) 773-7622, to have the device inspected and replaced.

Warranty Claim – If you experience a loss due to apparent arrester failure, please contact our Energy Services Department at (509) 773-7622 to make the report to start the claim review process. We will send a service man to replace the arrester and test the existing arrester. Claim forms will be supplied if necessary.
