Series of 12 black and white photographs of the construction of a new substation, during 1966 at the corner of Greville St and Punt Road, South Yarra. Shows the vacant block, construction of the foundations, walls and a part of the roof.

Set of four Polaroid prints of a Mercury Arc rectified bulb. One photo has written on rear "Hewittic Rectifiers type 500/6". Image i4 has a person standing alongside. See Inscriptions. Craig Tooke, formally of Yarra Trams substations advised 12/8/2020 by email to Warren Doubleday. "An interesting photo. I don’t know who the person in the photo is. More than likely the bulb in from an industrial installation such as mine etc. and not tram or train. The reason is that only Melbourne trams has Hackbridge Hewittic rectifiers that were used for traction. There was three sets of bulbs installed at West Brunswick, Deepdene and Preston. West Brunswick is definitely still in existence and probably Deepdene is still in existence as the old substation was abandoned intact and just left intact. Preston of course has gone and was removed as part of the work done at PWS. Another clue is the number 500/6 which means it was from a 500 kW – 6 bulb unit. The traction units were all in multiples of 150 kW per bulb i.e. the tramway ones were 600 kW rated. The number "40246" is the bulb serial number. Each bulb manufactured had an individual serial number. Interesting the bulbs at Brisbane Tram Museum have the following serial numbers to the ones that were at Essendon tram sub. The bulbs at Essendon of course are now up at Brisbane as spares."On the envelop with the photographs is "Keith Wilkinson Ph Orbost 051 510050" and "For Bill Kingsley 4/10/93".trams, tramways, substation, electrical equipment, electrical engineering, mercury arc

Megger as the device was called, is in fact its brand name. It is a device that supplies a DC (direct current as per car batteries) voltage to enable testing of electrical apparatus. This particular device produces 250volts DC when the handle is turned vigorously. If an electrical device, such as a kettle or toaster, blew a fuse or tripped a circuit breaker, when switched on, then it must be checked electrically before any more use. Following the repair of the faulty item a megger would be used to check if either of the AC 240volt plugs leads were touching the metal case (earth). The output leads of the megger would be connected with one to the earth (metal case) and the other to each of the power connections in turn. A good megger reading of 50,000 ohms (resistance) would enable the device to be returned to service. A reading of zero ohms resistance would mean that it would again blow a fuse, and was therefore unsafe to use. In the electrical industry e.g. the former State Electricity Commission, a megger would be used to test lots of similar item in sequence. Because of the vigorous job of winding the handle, two persons were often used to save time. One would crank madly whilst the other shifted the leads. This particular megger is of a small voltage, but other meggers are bigger and have a few ranges of DC voltages able to be selected. The optimal megger for large Generating machines was motor driven megger. This was applied to the device being tested for a duration of approximately 30 minutes with reading of the resistance taken at regular intervals.All equipment belonging to the State Electricity Commission of Victoria was labelled with a metal plaque attached to it. The SECV constructed the Kiewa Hydro Electric Scheme in the Upper Kiewa Valley and on the Bogong High Plains. The scheme began in 1938 and finished in 1961 when this megger was used and also possibly later as the SECV remained to maintain and operate the Scheme. This megger is of significance in relation to the advancement of technology.A rectangular box in dark brown bakerlite casing. It has an agent's plaque fixed to the left of the face and on the right is the marker's recessed stamp. In the middle in a transparent window so the level of ohms can be read. The front also has two recessed fixing knobs in black. On one side is a crank handle with a knob that lifts up and is turned vigorously to create the voltage. The back has four recessed screws and four small leather pads. There is a hole on each side to insert wires. There are two copper insulated wires. The SECV Plaque states: State/Electricity Commission/of/Victoria/ Electrical Engineer's Section/ No.1747 The Agent's Plaque states: H. Rowe & Co.

Its manufacture demonstrates from an industrial aspect a period of history following the occupation of Japan by the USA after the second world war and has a strong association with this event.Insulator - known as an egg type - ceramic - fired clay (porcelain) finished with a brown colour with two holes for span wire with the holes offset to each other. Marked in a very light almost clear finish on one side "Made in Occupied Japan" See item 8534 for another example - a larger size. https://www.gotheborg.com/glossary/occupiedjapan.shtml - accessed 15/4/20201 gives some background: "For the period from the end of World War II in 1945 through April 28, 1952, the United States and its Allies occupied Japan. The Occupation involved approximately 130,000 Americans (both military and civilian) and about 35,000 British Troops based in Japan. SCAP (Supreme Commander for the Allied Powers), led by General MacArthur, wrote a new constitution for Japan. As Japan needed to rebuild their economy after the war, part of the agreement to allow them to export goods out of their country was that they had to mark 50% of all items with "Occupied Japan" or "Made in Occupied Japan." This could be done with a paper label, cloth label (as on scarves, doilies, clothing), engraved, handwritten or stamped. Thus, you may come across things, such as a salt and pepper set, where only one of the pair is marked OJ and the other will just have "Japan" on it. The tags, labels, marks were placed on the items in Japan, before they were exported to other countries. "trams, tramways, overhead, trolley wire, insulation, electrical equipment
