This equipment acts similarly to a modern day circuit breaker found on the electrical circuit boards of residential homes. ...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
