This report covers a series of transformer room fire tests conducted by the General Services Administration (GSA). The tests were set up to demonstrate what shock hazard might be present when automatic sprinklers operated over energized electrical equipment. The test room was 25 feet long, 12 feet wide and 8 feet high. Fire protection was provided by standard one-half inch pendent automatic sprinklers temperature rated at 135 degrees F and installed to give approximately 150 square feet per head coverage. A 480 volt dry transformer was used in the room to provide a 3-phase, 4-wire distribution system, which is typical of the electrical systems found in GSA buildings. The tests showed that the induced currents in the test room during the various tests were relatively small and posed no appreciable personnel shock hazard. Detailed descriptions of the various tests, together with the results and conclusions, are contained in the body of the report.
