Polyphaser Data & Signal Surge Protectors
Polyphaser data surge protection devices are designed to protect sensitive electronic equipment from damage caused by surges, lightning strikes, and other types of electrical interference. These surge protection devices are typically used in data centers, telecommunications facilities, and other environments where electronic equipment is vulnerable to power surges.
Polyphaser data surge protection devices are designed to protect a wide range of equipment, including routers, switches, servers, and other network devices. They are typically installed between the incoming power or data lines and the equipment being protected, and are designed to divert surges and electrical noise away from the equipment. Polyphaser surge protection devices use a range of different technologies to provide protection against different types of surges and interference. For example, some devices use gas discharge tubes to absorb high-energy surges, while others use metal oxide varistors (MOVs) to suppress voltage spikes.

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.
