St. Louis - General Office April 12, 1968 TRANSFORMER AS KAREL PROMOTIONAL ADS H. S. Bergen - HEEBG N. x. Johaioa Gary Clark - GCLAB Following recent discussion* with General Electric (who approved our initial series of ads), the consensus now is that in future ads we should merely state that askarel transformers are flare-resistant. This is to say that we will not state that the arc-formed gases from askarel are noncambustible, and we will not state that no harmful amount of phosgene is formed. Since indeed the arc-formed gases of askarel fluid are noncoir.bustible, and since indeed on rechecking for phosgene. General Electric found no phosgene, there is good reason to ask why we do not emphasize these apparently favorable factors rather titan omit them--as we intend to do. What lies behind this is that in recent times, particularly,the utilities are placing a great deal of emphasis on the analysis of gases formed ia trans formers during operation, and especially coincidental with any fault. This is aimed primarily at mineral oil transformsrs,aad VPC apparatus is now recommended for monitoring transformers in ope ration. In light of this. General Electric are apprehensive, and we agree, that if we emphasise the nature of gases related to askarel transformers, we are unnecessarily inviting a host of inquiries that would then lead to utilities and other users seeking to make routine gas analysis on askarsl trans formers also. For example, although the arc-formed gae from askarel fluid is almost entirely Kd, which is noacombustiblc, the more practical consideration is that in a transformer system a lot of paper and cellulosic material is present. This then, is indeed a source of hydrogen and organic gases--which are combustible. This is to eay that on arcing, the paper ia a&askarel transformer acts Just about the same as the paper in a mineral oil transformer, and we do not wish to bring attention to this, or to raise questions aboutThis through our stating that the arc-formed gas from askarel fluid is aoncombustible. It will serve our promotional purpose fully adequately, and be much cleaner and simpler, to merely state in future ads that askarel transformers are fire-resistant. This is not to imply there is any harm or criticism of our previous statements, it is merely implied that if we had continued to emphasise these things, ws would open ourselves to unnecessary confusion and questions.

This ie the newer view by General Electric, and we agree. /ecd P. G. Benignue STLCOPCB4062957
