Q. What is a Power Gleaner Surge Protection Device (SPD)?

A.:    A Power Gleaner SPD is a passive electronic module that connects directly to the circuit panels of your facility. When one of our non-degrading SPD units senses a voltage surge that is greater than 10% over the rated voltage for that circuit, it instantly turns “on,” suppressing the surge by safely diverting it to earth ground. It quickly turns “off” when the transient is gone, and allows the normal power to continue flowing to your equipment.
    


Q. How does the Power Gleaner SPD prevent equipment damage?

A.:    Damage is caused by high voltage transients containing large amounts of energy that breakdown the input semiconductors and insulation of electronic equipment. By diverting this transient energy before it gets into the building distribution system, the SPD protects downstream equipment from damage. The same damaging affect applies to motors, lighting, HVAC and automation equipment.

Q. Why is “Electrical Pollution” the most costly to ignore and the least costly to eliminate?

A.:    Ignoring “Electrical Pollution” will eventually cost you thousands of dollars in catastrophic failure repairs, deteriorated equipment, lost production, wasted man-hours, corrupted computer data, downtime, etc. However, installing a relatively low cost Power Gleaner surge suppression system will eliminate these problems and protect your assets. It is much less costly than UPS systems, standby generators and other types of power conditioning equipment.

Q. Why is the Power Gleaner SPD System so innovative?

A.:    Power Gleaner has a unique SE Single Element Technology which uses individual large suppression elements capable of safely handling high levels of surge current. This insures that the suppressor will never degrade, even after multiple strikes. Many other surge protectors are constructed using small multi-elements in parallel to obtain high surge ratings. These small elements are prone to degradation due to unequal sharing of the high transient currents, leaving the user only partially protected.

Q. What do you mean by “non-degrading” SPD?

A.:    “Non-degrading” SPD means that the unit will not loose its ability to handle high peak currents with time or use. Power Gleaner uses large, 40 and 53 millimeter diameter MOVs (metal-oxide variable resistor) in all its '‘Non-degrading Single Element Technology” SPDs. This means that a Power Gleaner surge suppressor retains its full surge current capability for its lifetime with no reduction in its capability. Many other manufacturers use a large number of smaller MOVs in parallel to “build up” their ratings. This type of “multi-element” construction looses some of its ability to handle surges each time it operates. All Power Gleaner modules, from the S series rated at 45,000 amps per mode, all the way up to the Power Gleaner Triangle rated at 320,000 amps per mode, maintain full ratings for their lifetime. Your Power Gleaner dealer will be able to assist you in determining which units to use to achieve the maximum and most cost effective protection possible.

Q. How many surge suppressors do I need in my building?

A.:    The Power Gleaner SPD System works best when applied as recommended by the Institute of Electrical and Electronics Engineers (IEEE) Emerald Book. A high energy suppressor should be placed at the service entrance to the building, a category C primary location. This removes the high energy transients from the distribution system. Additionally, lower rated suppressors should be applied at the category B secondary locations on the distribution power panels for each critical load. This method of placing SPD modules creates a “cascading grid of protection,” protecting each individual load from any residual external transients as well as any internally generated transients.

Q. What does a “cascading grid of protection” really mean?

A.:    This is a term for the placement of Power Gleaner SPD modules at strategic locations in a facility so that all the equipment is protected from internally as well as externally generated transients. The primary protector at the service entrance performs the initial “coarse” suppression and then the secondary protector at a sub-panel or on a low voltage circuit performs a “fine” suppression, limiting the transient to harmless levels. This “cascading grid” of multiple suppression levels insures that there will be no equipment damage.

Q. How does Power Gleaner SPD provide “circuit isolation” from transients?

A.:    Connecting the SPD modules at power panels, in parallel with all the loads connected at that point, enables them to block transients coming from any direction and to effectively provide “isolation” of each load from the others connected at that same point.

Q. If I have panel mounted Power Gleaner surge protection, do I still need plug-in protection?

A.:    Plug-in protection is for category A locations. A plug-in protector alone without upstream panel protection at category B or C locations is ineffective. Plug-in protectors do not have the surge current capacity to handle large transients by themselves. When used downstream in a cascaded configuration, they can provide the best protection for very critical loads by clamping at the local 120 volt level. Whether the voltage is from inside your building (a motor switching on, for example) or from outside your building, unprotected equipment is damaged. This damage decreases efficiency and longevity of your equipment.
