Although the Kiewa Hydro-Electric Scheme was first proposed in 1911, construction did not commence until 1938. As part of the push to cut electricity costs and diversify supply, the Victorian Government (circa 1930) initiated the conversion from primarily brown coal supply to hydro – electricity. Field investigations during the 1940’s resulted in a new proposal for a scheme that had more than double the capacity of the 1938 scheme. The Kiewa Hydroelectric Scheme became the largest scheme of its kind in the State Of Victoria and the second largest scheme in Australia. The number of personnel involved in the planning and construction of the scheme increased dramatically. During the late 1940’s, most activity centered around the construction of the West Kiewa Power Station, Rocky Valley Reservoir, McKay Creek Power Station and the Bogong Creek Aqueduct.A common thread across all the larger hydro scheme constructions was the need for workers, both qualified and unqualified who came from around the world seeking a new life for themselves and their families. New accommodation and facilities were required for the army of workers engaged in construction in often remote and wild areas. The SEC had a high demand for timber, and set up the first of a number of sawmills at Bogong Creek in 1939 and set up the first hardwood logging in the headwaters of the Kiewa River. These new ‘towns’ such as Mt Beauty and Bogong, survived, serving the needs of operational personnel and their families, and expanding with growth of new industries. Mount Beauty, and to a lesser extent Bogong, are among these places.

This protection relay apparatus (a large electrical fuse), which permits the easy monitoring and disconnection of faulty electrical apparatus connected to the large SEC Victoria Hydro Scheme's electrical power producing generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro Schemes was achieved from the early 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This protection relay is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a small apparatus it was part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both an industrial and a larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley.This protection relay unit has a black painted metal shell with four copper enclosed "prongs" fastened to the rear of the housing(from a bake-lite plate) . Between these "prongs" are four "empty" points allowing additional "screw on" bases. The front glass enclosed meter and recorder allows for the identification and automatic disconnection of any faulty equipment connected to the main power generator. This equipment acts similarly to a modern day circuit breaker found on the electrical circuit boards of residential homes.On the top section of the front panel "ASEA" to the left "Made in Sweden" and to the right "Frabrique en Suede" below this "RIS" below this a graph and next to it two columns of numbers and a pointer for each setkiewa hydro electricity scheme, victorian state electricity commission, relays, generators

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 Optacon OPtical-to-TActile-CONverter is a compact, portable reading aid for the blind. It is about the size of a textbook, and weighs less than 2kg. It works by converting a printed image into a tactile image that a blind person can feel with one finger. After a period of training and practice, a blind person can use the Optacon to read ordinary books, magazines, newspapers, and other printed materials. The Optacon was developed after intensive research at Standford University, California, USA and was trialed by clients of the Royal Victorian Institute for the Blind (now part of Vision Australia) in 1973. It has three main sections: 1 a miniature camera, 2 an electronics section, and 3 a tactile stimulator array. The miniature camera, about the size of a pocket knife, is mounted in a housing that has rollers for easy movement along a line of print. The camera is connected to the electronics section by a lightweight cable. The electronics section and the tactile stimulator array are in the main chassis. The array consists of 144 tiny metal rods arranged in six vertical columns and 24 horizontal rows. Each of the rods can vibrate independently. The tips of these rods protrude through holes in a concave finger plate where the index finger is placed flat in order to read. These three components act together to convert the image of a printed letter or other shape into a pattern of vibrating rods, a tactile image of the letter or shape. The letter shape is tactually perceived as an image that moves from right to left on the finger, showing the left or leading edge of the letter first. Letters are felt sequentially rather than all at once, and the image should be kept moving. The Optacon converts a printed O into a tactile form that resembles a crater with a vibrating rim -- a completed circle. C would have a gap or opening on the right side of the curve. The letter F would be felt, sequentially, as a vertical line with two trailing horizontal lines. Because it can convert any ordinary printed image into a corresponding tactile image, the Optacon is not restricted to any special typestyle or language. The camera has a zoom lens that compensates for differences in the size of type. The standard Optacon lens can accommodate type sizes from 6 point to 20 point. With the optional F4A magnifier lens, type sizes as small as 4 point can be read. Powered by a rechargeable battery, and comes with its own battery charger. The battery is contained within the main chassis, and is not removable by the user. There are four basic controls on the Optacon: the Magnification Adjustment zoom button located on the camera section on the side opposite the rollers; and the On-Off switch, the Stimulator Intensity Adjustment knob, and the Threshold Adjustment knob located on the right side of the front panel. The Circuit Breaker protrudes from the right-hand wall inside the chassis compartment. From left to right when the back panel is facing you, are located: the jack for connecting the battery charger; the Battery Check button; the Normal-Invert switch; and the Input/Output I/O connector for use with the Visual Display, when using the Repeater Cable to connect two Optacons to one another or with other accessories. Designed not be removed from the leather case during normal operation, the On-Off switch is a slide switch located on the right side of the front panel. It slides up and snaps into place in the on position. 1 black with orange front, rectangular device in leather case assistive devices, audio equipment
