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

This case is for a testing voltmeter recorder. The last time it was certified by SEC Vic laboratories on the 17/4/77. It was used extensively in the transportation of the mobile recorder which was sometimes 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. See KVHS 0302 (A) for the instrument.This case for a 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 all leather top has a shaped carrying handle which is also riveted on. There are two straps on the side of the top which can be fastened to the main body by metal "shoe" buckles. The bottom end is secured to the main bag by large rivets.Tick grade stitching is on all corners.Nilsec vic kiewa hydro scheme, alternate energy supplies, alpine growth in electricity consumption

As part of the push to cut electricity costs and diversify supply, the Victorian Government (circa 1930) implemented the conversion strategy from mainly brown coal supply to hydro - electricity. The Kiewa Hydroelectric Scheme became the largest scheme of its kind in the State Of Victoria and the second largest scheme in Australia. Clover Dam and Power Station were built by the State Electricity Commission of Victoria as part of the Kiewa Hydro Electric Scheme from the late 1930's to the early 1940's. This dam was constructed to supply water to feed four turbines (62 mega watts) at the West Kiewa Power Station. This was at the forefront of sustainable "Green" energy. Costs associated with power supplies is still a major incentive of governments, however environmentally friendly alternatives such as wind and nuclear have also made inroads. The Kiewa valley and its surrounding alpine catchment were looked at(Victorian State Government), from the beginning of the twentieth century as a source of alternate power for an ever-increasing demand for electricity by growing population and heavy industrial areas within Melbourne City and State regions. Construction of dams, such as Clover Dam provided the large quantity holding areas of water required to turn the turbines at the various power stations to provide the electricity needed. The impact of these controls by moderating water run-off from the alpine regions is beneficial in reducing flooding from thawing of snow on the alps. This by-product allows agriculture and grazing to be less vulnerable to seasonal flooding thereby resulting in a more stable annual production level.Black and white photograph of Clover Dam with Kiewa River in flood. .5mm white boarder on 3 sides of photo.Handwritten on back of photograph in black pen - Kiewa in flood.
