	Subject - Mitigating Transformers lctrc789 I am sure that some of you have worked with these harmonic balancing transformers before, they are kind of new here in this country. I was always taught power in EQUALS power out 300 KVA in 300 KVA out. I had to take a course on these a few years ago VERY NEW to me never heard of a transformer that, has 300 KVA in and 360 KVA out. Has any one in here done any of these, in larger factories usually. I was surprised to find that no matter what kind of load you put on these Computers, electronic ballast, the nuetral was always at ZERO amps. I have only installed these in 3 applications in the last 6 years. JimmyDee This is new to me so I'm looking forward to learning something here. Jim Ryan_J Are you talking about a K rated transfomer? KSsparky Would this not amount to a transformer that is 120% efficient ? I don't see how this is possible. Do you have enough working knowledge of them to explain how they work ? Sounds very interesting. lctrc789 When we first installed the first transformer we had NO knowledge of it couldn't even get a schematic because of patents pending it is made and invented by a russian engineer. We had to call several people to get a diagram on this thing. I can tell you they have a seperate winding that actually comes from the primary side that hooks to the XO side that always produces a voltage that will eat up the unbalanced nuetral. You also have a seperate ground from the casing that minimum size for a 300 kva transformer is 500MCM to steel, or ground rod or water pipe. These things have a set of primary windings, secondary windings, and a primary to secondary winding to XO side that produces a voltage that will always take the demand factor of the secondary to a higher output. We asked this guy to explain it, and he said basically in the old days when an old car was running that you would see smoke coming from it and it was the heat from the crankcase and these transformers are self induced so they eat that so called heat up and re use it to balance the transformer as the PCV vavlve in a car. We have now installed two 300 KVA trans formers in a Large computer manufacturer building they both say 300 KVA in 360 out, The other one we installed was at a PHARMECUETICAL company and it was 112 1/2 KVA in and 135 KVA out. For years I was taught Power in equals power out but not true with these. I can find out more on these as time goes on. Right now you cannot get much info on them because of the patents pending. If some one does install any of these and gets info I would sure like to know JimmyDee Kind of sounds like a constant voltage transformer but they are very inefficient. Looking forward to seeing how these actually work and the concept behind them. Who actually makes these? Jim lctrc789 I am looking in to the manufacturer name on these. As I stated these things were so new when we installed them we couldn't get any answers because of the Patents that are pendingI beeive it was a Ruusian name I do know they were invented by a Russian engineer.I am trying to find more info on these myself. Will keep you guys posted.
