One of the greatest misnomers of the surge suppression industry is that the UL1449 Voltage Protection Ratings are a good basis for comparison of performance capabilities of SPDs. As a matter of fact, that assumption is only partly true.
We all know that IEEE recommends at least three levels of protection where it is possible, the object being to reduce the magnitude of surges entering a facility at the service entrance to a negligible level at the protected equipment. The added benefit of this approach is to reduce the impact of surges that are internally generated and may never reach the service entrance unit before damaging sensitive equipment within the facility. This is called the cascade or ‘systems approach’ and is the approach that SSI takes in providing complete TVSS systems.
One of the many things that I have learned over time is just because you are selling the most products does not necessarily mean that you are the one who is leading your industry. Another thing that I have learned at the "University of Hard Knocks" is if you are selling the most products you must keep up with the industry leaders or you won't be sales leader for long.
Before we get into the meat of the matter, let's take a few minutes to get back to the "basics" of surge suppression.
Our industry is fraught with alternate approaches to marketing products, which at times, tend to redirect the focus of what the product was originally designed to do. Occasionally, there is someone who comes along with valid points and pioneering ideas. These are the people who lead the industry and cause products to improve. Surge Suppression Incorporated falls into that category as the industry leader.
In this issue of our newsletter, we have released a much-requested video demonstrating the effects of transient voltage surges on two different types of light bulbs with and without a SPD attached.
