Black and white silver gelatin photograph taken inside Electricity Sub-station #2, Kodak factory, Coburg, November 1958.

Electricity Sub-station #2 was one of three sub-stations on the site (#1 in the Power House, Building 11, and #3 in the Garage, Building 14). Each of them supplied an adjacent group of buildings or equipment, with three phase 400 volt electricity. In this case, the outgoing circuits for this sub-station supplied Buildings 2, 3, 4, 5, 6, 7, 8, 9 &10. There were two separate incoming circuits, one from the Coburg City Council Supply, and the other from the Power House alternators.

In this view of the main electrical distribution board looking south-east, two sets (upper and lower) of isolating circuit breakers in individual openable cabinets for each building are shown. The distribution board was housed in an uncluttered brick walled, concrete floored room. Each building could be supplied from either one of the incoming circuits with appropriate interlocking to avoid these circuits being cross-connected (co-generation with the supply company was not allowed at this time). Since the Power House supply was considered to be much more reliable than the local council supply in terms of frequency of outages, the most important and continuous operations within the Kodak complex were usually connected to the Power House supply. Switching of buildings to either incoming supply, while not a frequent occurrence, was done to maintain maximum loading of the steam turbine driven alternators, and hence the highest efficiency of steam generation. Also, if one supply failed, building operations deemed to be the most important at the time, could be switched over to the alternative supply.

Kodak manufactured and distributed a wide range of photographic products to Australasia, such as, film, paper, chemicals, cameras and miscellaneous equipment. Its client base included amateur and professional photographers as well as specialist medical and graphic art professionals who used photography, x-ray and other imaging techniques.

This photograph is part of the Kodak collection of products, promotional materials, photographs and working life artefacts collected from Kodak Australasia in 2005 after the manufacturing plant at Coburg had closed down the year before.
