Electric Megger (Insulation Tester) and its case
... to the advancement of technology. electrical meters, electrical equipment ...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.

Photograph (item), The Telegraph, James Melrose with aeroplane My Hildegarde, 16 October 1934
This was the first press photograph transmitted by radio from England to Australia. On 16 October 1934, South Australian aviator, C J Melrose, was pictured beside his plane at the Mildenhall aerodrome, England, preparing for the start of the Centenary Air Race. Within hours of capture, the image was transmitted from London to Melbourne and then sent via picturegram to Sydney’s press, the greatest distance a photograph had been transmitted over radio. Wirephotos, as they are commonly called, are produced through electrical pulses which travel along telephone or telegraph wires, or radio waves. Like the transmission of Morse dots and dashes, the technology communicates the light and dark portions of an image, to be recorded on a negative or photographic paper at the receiver’s end. Previously, photographs of an event appeared several days after the fact; wirephoto technology enabled visual communication with relative speed. Our consumption and expectation of the immediacy of news and communication continued to grow, an expectation that forms the basis of time-based social media activities such as Snapchat or Facebook and Instagram stories.london to melbourne air race, wirephoto, picturegram, uiver, james melrose -

Photograph: Mr. George Thomas Teacher and Councillor CTS 1937-1972
Mr. George Thomas' connection with Collingwood Technical School began as a junior technical student at Collingwood in 1913. He then became an apprentice in the electrical trades during which time he also undertook a Diploma course in Electrical Engineering. Mr Thomas was appointed as a teacher (part-time) of Electrical Wiring at Collingwood in 1922 having had previous experience teaching in Geelong at the Gordon Institute of Technology. In 1930 Mr Thomas became a full-time teacher in Electrical Trades, the year of the commencement of the Apprenticeship Commission in Victoria. In 1937 he was instrumental in introducing electroplating as a trade whereas it had previously only been taught as a section of the Electrical Trades. This was a period of severe economic constraints following the Great Depression and spending on education was limited. Needing the latest knowledge of industrial practices, Mr Thomas canvassed electroplating industries around Melbourne seeking employment opportunities and met with favourable responses. He approached Quinton’s electroplating firm in North Melbourne with the proposal to work for them on Saturday mornings without payment. In return for his labour, he asked to be taught the basics of the trade. During the week he was able to impart his knowledge to his students. Initially, he wanted to develop electroplating as an outlet for the Youth Employment Training Scheme. Once the class was firmly established, he submitted a proposal to the Education Department to establish an Electroplating Department, and this became the first of its kind in the southern hemisphere. He gave up teaching in 1939 to become the Northcote City Electrical Engineer where he served for 26 years. During this time he was also a Consulting Electrical Engineer to Box Hill and Port Melbourne Councils. His association with Collingwood Technical School (and later, College) continued, first as an examiner on the State Electricity Commission (SEC) panel and from 1947 as a member of the School Council. He was president of the Council in 1961 and 1962. He also represented the College on the Northern Regional Council and participated in the selection of Electrical Trades teachers. For four years, 1967-1971, he represented the metropolitan Technical Schools and Colleges on the Council of the Monash University, in which capacity he gave outstanding service to technical education. George H. Thomas attended his first Council meeting on June 12, 1947 and remained on the Council until the secondary and post-secondary sections were separated in 1981 – a period in excess of 34 years. (See Scott p36).Black and white photographs of Mr. George Thomas who had a long association with Collingwood Technical School and Collingwood Technical College, spanning the years 1937-1972. He began his connection with the school as a teacher and went on to become a member of the School Council. He introduced Electroplating as a trade to be taught at Collingwood Technical School in 1937. (Scott p36) The photographs include one of Mr. George Thomas in Monash University regalia 1971.

Parks Victoria - Cape Nelson Lightstation
Instrument - Morse Code Key Set
The battery powered set, which dates from the second half of the twentieth century, comprises two main components, the electronic keyer with a single lever for tapping, and a transmitter (?), both connected by a keying cable. Morse code was invented in the 1830s by American, Samuel Finely Breese by using electrical signals to quickly transmit information over a long range. In the early 1890s Italian inventor, Guglielmo Marconi improved the technology to the point where it became an essential device used for commercial and government purposes. The first practical applications were demonstrated with maritime messaging, where this simple mode of communication was seen as a timely replacement for the historic practice of signaling by flags, lights and foghorns. Cape Schanck has an earlier Morse code key, which is original to the lightstation (CSLS 0035), and Cape Otway has another early example although its provenance to the lightstation has not been formally verified (COLS 0074). The Morse code set has first level contributory significance for its historical value as an earlier communications device that has since been made redundant by more sophisticated technologies.Morse code key set.

Domestic object - Ceramic KOOKABURRA Electric Jug, Nilsen Porcelain Australia, 1930s
Electric kettles were invented by the English to speed up tea preparation. In Australia fancy ceramic electric jugs quickly became a status symbol. During the Great Depression era anyone who could offer you a cuppa from a beautiful Electric Kookaburra Jug was considered to be doing well. Made by Nilsen Porcelain Australia in the 193Os, these kettles were unique for their charming art deco bird shape. Nilsen Electric Kookaburra Jugs are now regarded as a classic Australian icon prized by collectors. Oliver John Nilsen was born in Collingwood, Victoria in 1894. In 1916 he began his own electrical business, Oliver J. Nilsen & Co. (later Oliver J. Nilsen (Australia) Ltd). Nilsen's manufactured goods included such diverse products as transformers, bearings, battery chargers, bells, buzzers and gongs, porcelain ware, fuses, insulators and neon signs. Nilsen Porcelain Australia was a smaller company within the Nilsen group. Nilsen still operates as an electro-technology company operating throughout AustraliaThis jug is an excellent example of art deco ceramic appliances of the 1930s to 1950s on both a local and national level. It is also representative of products developed by a major Australian manufacturer.

Flagstaff Hill Maritime Museum and Village
Instrument - Foghorn, Late 19th century
A foghorn is a device that uses sound to warn of navigational hazards like rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used with marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rocky outcrops, shoals, headlands, or other dangers to shipping. An early form of fog signal was to use a bell, gong, explosive signal or firing a cannon to alert shipping. From the early 20th century an improved device called the diaphone was used in place of these other devices, The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides, the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, this air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would be repeated. This method of producing a low audible sound was further developed as a fog signal by John Northey of Toronto and these diaphones were powered by compressed air produced by an electric motor or other mechanical means that admitted extremely powerful low-frequency notes. The example in the Flagstaff collection is an early cased and portable diaphone used on pleasure or sailing craft. By manually turning the crank handle air is produced and fed into valves that direct air across vibrating metal reeds to produce the required sound. in foggy weather, fog horns are used to pinpoint a vessels position and to indicate how the vessel is sailing in foggy conditions. One blast, when sailing on starboard tack and two blasts, when sailing on a port tack and three dots, when with wind is behind the vessel. Since the automation of lighthouses became common in the 1960s and 1970s, most older foghorn marine installations have been removed to avoid the need to run the complex machinery associated with them, and have been replaced with an electrically powered diaphragm or compressed air horns. The example in the collection is significant as it was used in the early 19th century for sailing vessels was important but these portable crank fog horns have also been superseded by modern electric varieties. Therefore the item has a historical connection with sailing and maritime pursuits from our past.English Rotary Norwegian Pattern nautical foghorn within a boxed pine varnished case with exposed corner dovetailing, original leather carrying strap, brass side crank, and original copper trumped horn.
