This milli-volt meter was manufactured after 1950 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to measure very small voltages associated with the operation of the various Hydro Generators. The readings were able to be shown by the resistor in use in the current circuit. During this time period, high quality testing instruments were either sourced from Europe or England.This milli-volt meter is very significant to the Kiewa Valley as it was used by those electrical technicians, who were part of the Kiewa Hydro Scheme. An "off spin" from the Scheme was the beginning of an explosion in "human" resources into the Kiewa Valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both industrial and larger residential community. This evolution in the Kiewa Valley created a change, not only in the "physical" landscape(better roads and infrastructure), but also the socio-economic growth within the Valley allowing other "tourist" based industries to expand within the valley and Alpine areas.This millivolts DC meter was used in the 1950's. It is contained in a wooden box and has two coloured (red/black, positive and negative) screw tight knobs which have bake-lite connections. It also has a covered (black tin) view meter marked from zero to 10 millivolts. Underneath this and within a round bake-lite is a small adjustment screw. The top of the box is fastened onto the main structure by six brass screws. The back of the structure is fastened by eight brass screws and there are four small bake-lite rest knobs.On the face of the millivolt compartment , and at the top "TO BE USED WITH DIAL HORIZONTAL TEMP.

The first transistor radio (the Regency TR-1) was produced by Regency Electronics in cooperation with Texas Instruments in 1954. Transistor 4 , the AWA transistor radio was manufactured by Amalgamated Wireless Australasia Limited (AWA), Australia's largest and most prominent twentieth century producer of radios, televisions, audio and telecommunications equipment. Transistor radios went on to become the most popular electronic communication device of the 1960s and 1970s. Billions of transistor radios are estimated to have been sold worldwide between the 1950s and 2012. They were exceptionally popular amongst young people in Australia due to their portability, allowing them to be taken wherever you wanted to gather with friends or, due to the headphone attachment, without disturbing those around you.

When this AVOMETER was being utilised in the early 1950's it was at the "leading" edge of electrical measuring instrumentation.The first meter was produced by Automatic Coil Winder and Electrical Equipment Co. in 1923. This model was produced in the time from 1933 to 1951 when it was superseded by the most popular model, Model 8 (1951 to 2008).This AVO meter brought the measuring of three electrical power indicators i.e., amps, volts and ohms into one measuring unit. By using a "one fits all" unit, the carrying of separate measuring devices was reduced considerably. The need for a mountainous and a large area of operational requirements, such as the SEC Vic Kiewa Hydro Electricity Scheme, to minimise the weight of equipment carried by electricians and technicians was of the utmost relevance. The significance of this meter to the Kiewa Valley region relates to the impact of modern technology (at that time) upon a mainly rural environment. This equipment shows how the boost of "modern" equipment into the area because of the "Hydro Scheme" was facilitated a lot faster than would have taken under "normal" evolutionary time. The speed of information on all "new technology" had a relatively slow assimilation rate to those living in rural communities. This AVOMETER is a Model 7 MKII, production pre 1951. This meter measures electrical Amps, Volts and Ohms and has two internal batteries for its power. The main casing is made from aluminium with a bake-lite front. The front has a "window" detailing, with a needle pointer, the amount of electrical power being tested. There are two big dial switches, detailing Direct Current(DC) and Alternating Current(AC) when reading measurements of Ampere, Voltage and Ohms for power. This meter took the place of three or four meters used earlier. Modern meters (2000 onwards) have become digilised and are considerably lighter in weight and smaller. There are two electrical connection leads (one black and one red) each has a removable clasp and is 125cm long.Molded on the front centre panel " UNIVERSAL AVOMETER". Below this and above the left hand dial "D.C. SWITCH" .Above the right hand switch the right "A.C. SWITCH". On the left of each switch is an arrow pointing to it.The left switch is marked with a "+" and the right one with a "-". There is a "divisional 2" mark. Between and below the dials is "CUT OUT" plunger.electrical meters, electrical equipment, sec vic., state electricity commission of victoria, mt beauty, bogong village

This Timing Relay is quite a large (industrial type) apparatus. The Timer is started by having a voltage of 250 volts direct current (as supplied by batteries). A DC motor then rotates driving into a clockwork mechanism, the output of which is an arm rotating at the same speed as a minute hand on a clock. Attached to this arm is a mercury switch which tips and makes an electrical circuit operate in a sequence control system. The sequences that use these timers are when starting and stopping Hydro Generators. They check that the machine has connected to the power system grid before 20 minutes duration. Brakes must go on for a set time when shutting down a generator slowing at the right speed as measured by this apparatus. 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 mid 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 Timing Relay apparatus is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a relay apparatus, it was however 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 Hydro Scheme was instigated by "the Government of the day" as a bold move and was the major force behind the acceptance of World War II refugee and "technical" workforce. Inclusion of skilled and unskilled migration into the Australian environment was of a higher priority than a selective quota system of later years.. 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.sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth
