Polyphaser DC Line Surge Protection
Polyphaser DC surge protection is a type of technology designed to protect electrical equipment from damage caused by surges in voltage. These surges can occur due to lightning strikes, power grid fluctuations, or other electrical disturbances. Polyphaser DC surge protection devices work by diverting excess electrical energy away from sensitive equipment and towards a grounding system.
Polyphaser DC surge protection devices typically consist of a series of components, including surge suppressors, DC blocking capacitors, and inductors. These components work together to protect equipment from both high-frequency and low-frequency surges, which can damage or destroy sensitive electronics. Polyphaser DC surge protection devices are commonly used in a variety of applications, including telecommunications, power generation, and industrial automation. They are particularly important in settings where sensitive electronics are exposed to outdoor environments, such as cell towers, radio transmission sites, and wind turbines.

Surge Protection Basics
What causes power surges?
Lightning strikes are one of the most common causes of power surges and can affect an electrical system even if the strike occurs miles from the electrical source. Conductors buried underground can still transmit the energy of the strike to electrical equipment located indoors. Lightning rods and other grounding equipment can help, but do not completely eliminate the risk.
Switching equipment such as motors, transformers and other equipment can cause a sudden change in load, power loss and disconnection of circuit breakers. This sudden switching can cause overvoltage, leading to power surges. The closer the switching occurs to the electrical system, the more threat it will pose to the equipment.
Operations that a user performs can cause surges, but typically have a very short duration. Examples include: starting a motor, opening circuit breakers and welding equipment.
What is the best way to stop power surges?
By using transient surge suppressors, the problems associated with most transient surges can be eliminated. They provide protection by either blocking or shorting the voltage over its operating limit to ground, protecting circuits downstream of the suppressor. The best way to approach this is in tiers.
Tier 1 – The protection is closest to the incoming power source. This is the main protection for a particular location.
Tier 2 – This is in an area that will be protecting multiple devices that have branch protection. An electrical control panel would be an example of this type of application.
Tier 3 – Individual protection. In the case of an industrial control panel, this would be protection for each instrument entering the panel.
