Victorian Institute of Occupational Safety and Health (VIOSH) Australia is the Asia-Pacific centre for teaching and research in occupational health and safety (OHS) and is known as one of Australia's leaders on the field. VIOSH has a global reputation for its innovative approach within the field of OHS management. VIOSH had its first intake of students in 1979. At that time the Institution was known as the Ballarat College of Advanced Education. In 1990 it became known as Ballarat University College, then in 1994 as University of Ballarat. It was 2014 that it became Federation University. VIOSH Australia students are safety managers, senior advisors and experienced OHS professionals. They come from all over Australia and industry. Students are taught active research and enquiry; rather than textbook learning and a one-size fits all approach. VIOSH accepts people into the Graduate Diploma of Occupational Hazard Management who have no undergraduate degree - on the basis of extensive work experience and knowledge.

Edward ( Ted) Salamy (1903-1977) succeeded his father in business in Warrnambool as a jeweller and was at 179 Liebig Street when he retired in the 1960s. On 1st December in 1924 he obtained an amateur radio licence ( Call sign A3AJ). This was the 35th licence issued in the State of Victoria and the first in Warrnambool. The original licence cost two shillings and sixpence. Amateur radio, still a popular hobby today, was particularly important in the 1920s when few people had radios of any sort and there were no provincial radio stations. People were able to access amateur radio sets to listen to such broadcast as overseas cricket matches. This amateur radio set is of considerable historical importance as it belonged to Ted Salamy, credited with being the first to operate an amateur radio station in Warrnambool.This is a rectangular box containing five valves, a radio frequency mechanism and three coils with fine copper winding. The mechanisms are connected by wires and metal screws. The box has a raised black -composite material front which has a voltage meter, three switches or knobs and a tuning dial.

This insulator disk for the high voltage carrying electrical cables was manufactured in 1964 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to connect high voltage cables to their "towers" going from various Hydro Generators to and from power "stations". During this time period, high quality "cable" insulators were manufactured in Japan. In an earlier time they would have been sourced from Europe or England. After the 1950's the sourcing of electrical hardware was being influenced by the lower costs obtainable from Japan. Later on other Asian sources also became available.The need for a mountainous and a large area of operational requirements, such as the SEC Vic Kiewa Hydro Electricity Scheme, to distribute the electricity produced in the Victorian Alps to the major users required power transmission lines to "carry" high above the sometimes inaccessible land mass electricity generated at the power stations to the various sub stations along the valleys and ranges to flatter populated regions. The significance of this insulation "high voltage" disk to the Kiewa Valley region relates to the impact of modern technology (at that time) upon a mainly rural environment. These power lines are a stark visual "show" of the impact that the "Scheme" has on the mostly rural landscape of the Kiewa Valley and what a boost of "modern" equipment into the area has taken place. The "Hydro Scheme" had facilitated the transition of a semi rural area to an advanced rural region within a shorter time frame, than would have taken under "normal" evolutionary time. The speed of information of all "new technology" had a relatively slow assimilation rate before the SEC Kiewa Hydro Scheme came to those living in the then quieter rural communities. This high voltage (330 KV) insulation disk is made from non conductive porcelain stoneware. It is highly polished brown in colour and has a clip fastening for the high voltage cable to be attached to. This disk was hit by lightning and the burn marks are quite noticeable. The top metal connector has a "mushroom" extension jutting below the semi cone like insulation disk. Also four circular ridges or grooves (old 78 rpm disc recording style).Cable bell on top of insulation disk "4K " next to it the international symbol for electricity (triangle containing one horizontal line under one V line and one vertical flame like line.)

An induction coil consists of two coils of insulated copper wire wound around a common iron core. One coil, called the primary winding, is made from relatively few (tens or hundreds) turns of coarse wire. The other coil, the secondary winding, typically consists of many (thousands) turns of fine wire. An electric current is passed through the primary, creating a magnetic field. Because of the common core, most of the primary's magnetic field couples with the secondary winding. The primary behaves as an inductor, storing energy in the associated magnetic field. When the primary current is suddenly interrupted, the magnetic field rapidly collapses. This causes a high voltage pulse to be developed across the secondary terminals through electromagnetic induction. Because of the large number of turns in the secondary coil, the secondary voltage pulse is typically many thousands of volts. This voltage is often sufficient to cause an electric spark, to jump across an air gap separating the secondary's output terminals. For this reason, induction coils were called spark coils. The size of induction coils was usually specified by the length of spark it could produce; an '8 inch' (20 cm) induction coil was one that could produce an 8 inch arc. (http://en.wikipedia.org/wiki/Induction_coil)A metal and plastic object on a timber stand. In an induction coil the distance between the plates is often used to measure the voltage of the spark since the air breaks down at 30 000 volts per centimetreballarat college of advanced education, scientific instrument, induction coil, scientific instruments, electricity

This testing voltmeter recorder was last certified by SEC Vic laboratories on the 17/4/77. It was used extensively as mobile recorder placed for periods of one month at locations experiencing unacceptable fluctuations of power. These locations would cover the North East regions of Victoria. They cover voltage drops at domestic and business properties especially those that were experiencing regular fluctuations(daily) at approximately the same time of the day. As the electrical network is required to operate within a set level of voltage, fluctuations outside of this has to be investigated and necessary remedial action taken. This is especially so for rural properties where power "drainage" can occur through animal/bird and tree interference. It can also be the result of defective wiring and overloading at peek operational times (milking machines).This mobile voltage recorder is very significant to the Kiewa Valley because it highlights the difficulties that can occur in maintaining a power supply that experiences fluctuating power demands by the rural industries that it supplies. The requirement of a mobile testing apparatus to cover the various sections in the Kiewa Valley and other rural areas in the northeast region is one of necessity as electricity once connected to a rural property is a labour saving supply as generators on rural properties require a higher degree of maintenance an ultimately at a higher cost. The testing of the SEC Vic supplied electricity to rural properties,those who had previously run on generators, had to be quick and unassuming with certainty of correct supply levels.The mechanism of this voltage recorder has been installed(by the manufacturer) into its own protective wooden box. This box has a front (swing open) lockable section which permits direct access to the installed measuring equipment (for servicing and data collection). The top section of the box has two screw on terminals for access to the machine being tested. This tester has its own inbuilt ink supply facilities and a mechanical clockwork device that unwinds a roll of paper onto a second roll at a rate of 10 mm per hour. The recording chart is marked with time slots against voltage. There is a recording arm which has an ink pen at the end. Both arm and pen carry the ink supply from the ink reservoir, located on the left side of the cabinet door in specially constructed bottle holder( three small bottle capacity). To record a suspect power problem to a home or business establishment the voltmeter is connected to a power supply outlet being tested and wind the recording clockwork mechanism (gives a four week running time). Before leaving the recorder in situ the electrician checks to see if the chart is recording the correct voltage and that the clock mechanism is advancing correctly.On the front of the access "door" at the top a metal label "RECORDING AMMETER" below this "MURDAY SYSTEM" below this "ALTERNATING CURRENT" and below this the manufacturer's registered number "No. 139156" Below this is a metal tag with State Electricity Commission of Victoria Electrical Engineer's Section equipment number "338" Below these tags and above the viewing window is the manufacturer's dtails "EVERSHED & VIGNOLES Led LONDON"sec vic kiewa hydro scheme, alternate energy supplies, alpine feasibility studies temperature, rainfall, power outages

A shock of different voltages was delivered to a person using the two metal handles or two heavy soft wire combs (missing but known of) were moved across the skin. Perhaps this was an early TENS Unit. The unit came to the donor's grandfather (Roy F. Leibig - Chief Electrical Inspector of the Brunswick (Melbourne) Electric Supply) for repair and returned to his keeping once it had become obsolete (upgraded by newer machine). Donor often helped his Pa repair electrical equipment.Historical: The Resuscitator or Electric Therapy Unit was used in hospitals, possibly Mental hospitals. Provenance: The donor worked at Mt Beauty in the Kiewa Hydro Electric Scheme with the State Electric Commission of Victoria as an electrician.

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.
