X.4031 - WESTINGHOUSE VIBRATOR REGULATOR (WITH COMBINED CUT-OUT) Further to our EFC4/T25.10.20 we have now made an experimental bench investigation of the operation of the Westinghouse combined cut-out and vibrator regulator sent to us from U.S.A. for test. Our tests have been carefully carried out with due consideration to all the points involved, and would indicate that this piece of apparatus is not suitable for doing such work as it is felt is required to make the characteristics of the chassis electrical system as nearly ideal as possible. Together with our EFC4/T25.10.20, already referred to, we issued a diagram and description of connections ofthis instrument. We are now passing on the instrument to Mr. Royce for his inspection as we think he would like to see this, although we do not think anything more is to be gained by further experimental work upon it. Most of our work on the instrument was carried out with the cut-out put out of operation, by wedging the contacts together, as it was latterly more particularly our intention to investigate the operation of the regulator. We had commenced, however, by investigating the cut-out operation. We do not Contd. | ||
