Test of Model GO Transformers (Contractor: Hygrade Sylvania Corporation)
Abstract
Of the two defective transformers sent to the Laboratory, one had been disassembled and no cause of failure could be determined. The second transformer had a severe gash in the secondary winding as shown by the accompanying plates. This gash was a mechanical fault whose appearance showed it could not have been caused by overheating and whose location was such that it must have occurred at the time the transformer was wound. Undoubtedly the gash caused the failure of this particular transformer. The replacement transformers are of toe same design as that of the production model now at the Laboratory. Overloads, excessive heating, short circuits, vibration, high humidity, use of 500 cycle power supply, and use of poor rectifier tubes failed to cause a single transformer failure and consequently the fundamental design is considered adequate for the requirements of the circuit.
