Instruction to Ballarat motormen and depot staff dated 13/1/1950, about ensuring the controller was closed in the off position before opening the automatic circuit breaker. Appears this was not done on tram 14 and a fire resulted. Significant damage can result of the action. When the tram was rewired during 2024, this fire damage was apparent.

Controller from an old tram, possible Tram 22. Appears to be a typical parallel drum controller with the casing removed. The arc shield is in place. With this swung back the drum segments and fingers are revealed. The controller is supplied with power via a current limiting automatic circuit breaker. It has a handle on top and this turns a drum fitted with insulated copper segments. There is usually a star wheel and roller which ensures that the drum advances in notches to match the drum segments.Large laminated photograph of a tram controller c1920controller, tramcars, parallel drum controller, automatic circuit breaker, handle, star wheel

Protective relays are one of the critical components of the elctrical power grid that serve to detect defective equipment or other dangerous or intolerable conditions and can either initiate or permit switching or simply provide an alarm to provide an alarm to provide a safer, more reliable delivery system. Used in power stations. The function of relay is to quickly remove from service any equipment that might suffer damage or otherwise affect the operation of the system. Relays protect the electrical system in 2 ways: Prevent failure or damage to electrical systems. Mitigate the effects of failure when it occurs. Switches that control other switches. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal.Used by the State Electricity Commission of Victoria for the Kiewa Hydro Electric Scheme in the power stations. Manually operated by remote control for an external circuit breaker. The relays were from a Kiewa Hydro Power Station control panel.Collection of black metal rectangular boxes (heavy) containing electrical wires forming a circuit. The longer, narrower rectangles have a bakelite knob at one end. Some of the boxes have one side of clear perspex and another has all sides of clear perspex. One is labelled "group relay". Another has windows with labels eg. 'turbine overspeed' 'emergency trip' and one has 3 steel knobs. - with 'stop', 'start'. One box is larger than the rest and has clear perspex side showing 'overcurrent relay' and workings.One has a plaque attached. Manufacture: "The English Co. Ltd.

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.

Item used to contain the compressor fuse on tram 14, salvaged during the project to renew the wiring of the tram. The box was located alongside the circuit breaker at No. 2 end of the tram. Demonstrates an item fitted to a tramcar to contain a renewable fuse.Wooden box containing a fuse, fuse holder and short sections of associated wire. The fuse holder is secured to the base of the box with brass screws. The box has a cover secured with a brass screw. There are two pieces of wire secured on the ceramic fuse holder, one of which the insulation has deteriorated and fallen off. The other wire has its cloth covered rubber insulation remaining in position. The outside of the box has been painted with the SEC tram green paint. fuse, tram 14, tramcars, tramcar maintenance

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
