Set of two brass manufacturing / data plates from the BTM Isolating transformer that failed Oct. 2004 and sent to ABB's Yarraville Workshop for assessment. Recovered from the transformer by ABB staff following inspection. Plates detail Manufacturer (State Electricity Commission of Victoria), ratings, connection diagrams, windings and date of manufacture (1931). These plates did not reflect the re-winding characteristics, but its original manufacturer. Transformer No. 1267. Each plate has four corner holes. Transformer acquired by the BTPS 1973 for re-winding from the SEC. See Reg.
