Why Surge Protection?
Until the introduction of solid-state devices, most AC-powered equipment was too insensitive to be upset by “dirty” or surging power. However, electrical power surges and the damage they can cause are commonplace today. Our home and workplace are comprised of solid-state
devices vulnerable to surges. We deal daily with computers, office machines, data, telecommunication equipment, major appliances, etc. All of
these depend on solid-state devices, which are vulnerable to surge.
Solid-state devices depend on consistent, good-quality power. A single powerful surge literally melts, welds, pits, and burns its way through
solid-state circuits and components.
Device failure is often the result of surges and the cause is not detected by the repairing technician. In addition to the loss of use, the priceless stored data is lost and meaningful input or output information is turned into nonsense. The driving force to shrink device geometries to increase speed and storage capacity will continue to make solid state devices even more sensitive to AC power.
Many people think of surge damage as being caused by a single, catastrophic event such as a lightening strike. While lightning is one of
the most powerful and destructive surges, it’s not always the cause of most of the surge damage. In reality, surges range from mighty to the
minuscule.
Smaller surges occur several times a day, or hundreds of times an hour. Almost continuous surge can be produced by sources ranging
from 250 to over 1,000 volts. Typically, they are caused by the operation of electric motors or other inductive loads such as elevators office machines, HYAC equipment and material handling equipment. Microwave ovens, vacuum cleaners, lamp dimmers and countertop appliances are
some of the surge sources in the home.
Powerful, random surges result from the switching of an inductive load such as an electric motor starter, arc welder, furnace ignition, compressor, etc. and these momentary surge sources range from 250 to over 3,000 volts.
Over or under voltage power conditions of 250 to 6,000 volts usually accompanies a utility switching lines to meet changes in demand, or when
correcting a brownout or blackout.
While Mother Nature provides the most visible and spectacular surges in the form of lightning, the power company, your own equipment,
other equipment in the building you occupy, or from a source some distance from your facility can generate the surge damage you suffer.
Surges travel on AC lines, data lines, communication lines, coaxial cable, metal fences, metal conduit, metal duct work, as well as through the
ground and air. Surges travel via any conductor they can find.
Surge damage can be classified into three categories:
- Hard Failures
• Glitches
• Latent Failures
Hard failures cause damage requiring repair or replacement of electrical components. Glitches usually do not cause permanent damage,
just temporary damage or lost data.
Latent failures result from continuous exposure to smaller, non-catastrophic surges that erode equipment and its performance. In the end,
the equipment suffers hard failure and the cause is unseen.
Noise is another problem in power lines. Conducted noise is the most destructive type. It is usually present in your AC power source and
you are surrounded by these radiated noises.
Noises can come from the simplest device, such as an electric razor or a fluorescent lamp. Cars, TVs, cellular phones, electrical transformers, lamp dimmers, office machines, etc. are other examples. The list is endless. To solid-state devices, this is an invisible and lightning-fast
destructive force.
A high quality surge suppression system is your first, best and only defense against these potential threats to your equipment, data and
operation.
In designing the system, many factors should be taken into consideration. Every facility had some equipment that is critical to the overall operation of the facility. That equipment will probably require higher levels of protection.
How susceptible is the equipment to a surge? Equipment controlled by solid-state device is more susceptible to surge damage. Each facility is different and will require different levels of protection for perhaps even similar pieces of equipment.
The Institute of Electrical and Electronic Engineers (IEEE) has developed a schematic showing the levels of surge severity relative to location and showing even the point of entry of the electrical line. If surge sensitive equipment is located on the same circuit as equipment that generates surges, it must have protection. The only way to properly design a system of protection is careful evaluation of each and every facility.
Different surge suppression units offer varying levels of protection. All have the same basic job, to prevent damaging voltage spikes from
reaching the device it is intended to protect. More sophisticated suppression units also filter noise.
Only a thorough survey of your facility and its power supply, an examination of electrical layout, circuit plans and inventory of devices
(present and future) connected to all circuits can provide the information to form a recommended plan of protection.
High quality surge suppression units, when properly applied in surge suppression systems, are one of the best investments you can make.
Considering the small cost, it will be hard to find a higher return on any investment.

Surge Protection Function, Ratings, Testing & Warranties
Surge Suppression: Is by definition over voltage suppression. This is suppression of momentary over voltage of any cause. Surge suppressors are technically called TVSS (Transient Voltage Surge Suppression)
devices.
Surge Protector Rating: The rating of surge suppressors and their pass voltage is normally measured by
UL standards or ANSI/IEEE standards. All PSI surge suppressors are tested to ANSI/IEEE “B3” impulse
standards.
Surge Suppressors Pass Voltage:
The actual pass voltage of a surge suppressor (TVSS) is the most important measure of performance and is
the voltage level to which the connected equipment can be expected to be subjected. If the pass voltage is
above the damage threshold of the equipment, it has not provided your equipment with adequate protection.
Exaggerated Claims: Over the past few years, manufactures have been claiming their surge suppressors
can withstand very high amperage surges. Some of these claims are for a withstanding ability of 100,000
amps or more. These claims can be impressive if taken on face value and are not compared to the way UL
and
ANSI/IEEE test and rate surge suppressors. Surge suppressors are only rated in pass voltage by UL. The highest
recognized testing level is the ANSI/IEEE “C3” impulse of 20,000 volts and 10,000 amperes.
The ability of a surge suppressor to withstand “100,000 amps” is only telling you the surge suppressor may
survive a massive surge, not that your equipment will not be damaged or destroyed. The function of a surge
suppressor is to protect equipment from overvoltage, not to protect itself from a massive surge. If a surge
suppressor is sacrificed while protecting your equipment, it has done its job! Would you be happy if your
surge suppressor is unharmed after a massive surge and your equipment is destroyed?
Warranties: High quality surge suppressors normally have a lifetime warranty. If they are damaged due to
surge (lightning included), the surge suppressor is replaced free of charge.
Stormin Protection Products, Inc.’s Philosophy of Surge Suppressors & Warranty Policy: Our surge
suppressors are manufactured with the finest components available and are tested numerous times during
and after production to be sure they function properly. They are designed to protect your equipment. They
will withstand all but the most massive surges and restore themselves automatically after a surge occurs. All
our surge suppressors carry a lifetime warranty and will be replaced free of charge (see product warranty for
details). We will be happy to provide you with test results for any of our products. We will test to ANSI/IEEE
B3 impulse test standard any product you are considering purchasing, side-by-side with our equivalent product. You can then make a price versus performance evaluation of the surge suppressors you are considering.
How do you decide which surge suppressor meets your needs?
The first step is to determine the threshold level at which the equipment will be damaged by momentary
overvoltage. We can assist you, or you may contact the manufacturer of the equipment requiring protection.
The next step is to determine the style and type of connector etc., required for your equipment. Last step is
to make a price versus performance evaluation.

Main and Sub-Panel Protectors__________________________________________
Main and sub-panel surge suppressors usually come in two general types, series protectors and parallel protectors. Series protectors are load bearing devices and have to conform to the current the power company delivers to the main or sub-panel. Parallel protectors are non -load bearing devices and therefore can be used regardless of current delivered to the main or sub-panel.
Series protectors are usually very expensive and require breaking the incoming line to install. Parallel protectors are usually installed on the load side of the main breaker and are quite efficient. Underwriters Laboratories (UL) under 1449, has chosen to rate
surge suppressors in pass-through voltage categories. There is one serious fault in their testing.
Some manufactures of parallel type surge suppressors utilize plug-in modules, which allow for the replacement of damaged modules.
The ratings are obtained at the module itself without consideration for the length of wire required for the installation. A module rated
at 400 volt pass voltage with an additional two feet of wire added for the installation actually becomes a 1000 volt pass voltage. When
placed in a 24” x 24” box, two feet of wire would be minimal for the installation, therefore ratings of this modular type panel protector
can be deceptive.
Surge suppressors are designed to protect the electrical and electronic equipment to which they are connected. In rare cases, when
extremely large surges occur, the surge suppressor will
be sacrificed to save the protected equipment. This is the purpose of a surge suppressor. Some surge suppressors claim to have rating
of 100,000 amps or more. The ANSI! IEEE 587 and UL ratings have a maximum test of 10,000 amps. This is more than adequate for
the main service electrical entries.
The measurement of a surge suppressor’s performance is the pass voltage (actual voltage) your equipment sees after a suppressor
does its job. High current ratings do not mean low pass voltage. Our surge suppressors have a lifetime warranty and have been protecting customer facilities and equipment for 15 years. During this time our customers have experienced no equipment losses.
