These are pictures of two of three routers that were damaged during our real world surge protector comparison. There were two routers damaged that were the same model (Router 1). Also damaged was a PC monitor.
Below are pictures of the actual plug-in suppressor units used in our example. These units were protecting the power side of a home network that included multiple electronic devices...
Each surge protector was in the field at some point during the five year span of our review.
Below are three different SPD units displayed.
Two of the power surge protector units were replaced within an eighteen month period.
During the 18 month period: one monitor and 3 separate cable routers were damaged and had to be replaced. It wasn't until the 3rd surge protector unit was installed that the problems ceased.
During the 18 month span... there were no power outages, lightning strikes or other large electrical anomalies of note.
Without the presence of large surge events, it's reasonable to determine the damage to the equipment was caused by continuous internal transient voltage.
It's also reasonable to determine that most of the internal transients were RingWave type surges. The first two surge protectors did not provide RingWave protective circuitry.
However, a second protective device did provide EMI/RFI filtration circuitry. Some confuse EMI/RFI as being the same as high quality RingWave protective circuitry. This circuitry is referred to as Sinewave Tracking or Frequency Responsive CircuitryTM.
Do not be confused. They are not the same.
The equipment lost do to damage over the 18 month period...
This unit was the first power surge protector used to protect the electrical gear. Using this particular device... one monitor and one cable router had to be replaced. This was over a 6 month period.
This unit was the second power surge protector used to protect the electrical gear. Using this particular device two cable router units had to be replaced. This was over a 12 month period.
This unit was the third and final power surge protector used to protect the electronics. This particular device has been in service for 3.5 years. Update: Unit has been in service for 10 years.
No connected equipment has been replaced.
This device has been a great modem surge protector as well.
Overall, the power surge protector has lived up to it's marketing for all connected equipment involved. So effective... I now have additional 6 receptacle-plug-in type units and a dual, portable/travel unit.
The results of our real world comparison leads to one conclusion.
All surge protectors are not created equal. They do not always perform as claimed... in the field... regardless of what marketing materials might state.
Again, all three units were marketed to protect electronics. Only one succeeded.
It's also important to understand what types of surges are active in a particular environment. As noted previously, there are impulse type surges and RingWave type surges.
In an environment that produces both types of surges, surge protectors that protect against impulse and RingWave transients provide the best surge protection results.
The real world comparison certainly make this case.
One should take into account the types of technologies, design functionality, quality and dependability of the surge protector units before purchase...
It doesn't matter if it's a whole home surge protector, industrial surge protector, modem surge protector, cable router surge protector, plug-in unit or other SPD. There is no substitute for Quality and Performance.
Our gear is often imitated... but rarely duplicated... The Surge Stops Here.
