The Weston cell, is a wet-chemical cell that produces a highly stable voltage suitable as a laboratory standard for calibration of voltmeters. Invented by Edward Weston in 1893, it was adopted as the International Standard for EMF between 1911 and 1990.[1] This is a type of standard cell, which is a battery that produces a precisely known voltage in laboratory conditions at 20 degrees centigrade.[2]Brass cylinder with 4 connections at top.

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.

This analog voltmeter is quite a large (industrial type) apparatus which permits the easy monitoring of electrical variations within the large SEC Victoria Hydro Scheme's electrical 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 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 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 voltmeter 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 analog volt meter has two metal rods protruding from the "back" of instrument with screw on points for the negative and the positive leads allowing the "current" to flow across the calibrated resistors to indicate on the "face" side the strength of the voltage "power". The "face" of the instrument has a zero point and then five evenly graduated marks from Zero to the "100, 200 and 300" marked points of measures. A large "V" below these pointers indicates that they represent levels of voltage. Three small screws hold the "face" in place. At the back of the meter is an aluminium "clasp" with three protruding screws (positioning fasteners) and a a screw tightening fixture for the correct fastening of the "clasp" into the correction location on the meter "board".Manufacturer's logo "CSG" underneath "ITALIA"kiewa valley tourism, victorian alps, alternate energy supplies, alpine population growth
