A SEVERE MEDICAL PROBLEM TODAY
As we are called to look at power problems everywhere we have found one universal headache in every city and every state. All hospitals, clinics and heavy electronic users complain that their equipment works only occasionally and even then not well. And since all of them suffer together they have come up with a common solution which does help them. They call them harmonic transformers. The problem is that there is no such a thing. What they are really doing is isolating their problems to one location with isolation transformers. This is a band aid approach.
High harmonics which is the problem for everyone are created by all the new power supplies that come with all electronic devices which even include fluorescent, LED, and High Pressure Metallic lighting. Each power supply is adding a very small piece of harmonic disturbance. Since we have added so many electronic systems everywhere, the combined small pieces have added up into such large amounts that they have become a nightmare as this distortion attacks the very equipment that creates it.
Hospitals now have sophisticated electronic devices in almost every patient room let alone all that is used for diagnostic purposes outside of the patients location. This almost excessive amount of harmonic creation has gradually created a severe problem. X-Ray and other devices that depend upon accuracy to do their work are under attack from all the harmonic disturbance that exists in the electric power they must have to operate. So the quick assistance is to put expensive isolation transformers everywhere because they understand that the power is the problem without knowing what to do.
In only a few locations, including military medical facilities, we have used our harmonic filters to economically solve this headache for a whole section and not just where isolation transformers do selective assistance. The answer is to eliminate the harmonic disturbance in the line not just isolate it. Several hospitals have learned what we are doing and are waiting for us to grow enough to serve many of them and not just the few we have been able to work with to date.
