Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.

The Victorian Gold Jubilee Exhibition, held at Bendigo from 13 November 1901 to 14 May 1902. The courts were numbered from one, or had titles like “Machinery”, “Agricultural”, “Naval & Military Court” and “Art”. The female visitors to the Exhibition were able to view exhibits deemed suitable for the fairer sex and located within their own “Women’s Court”. There were exhibits such as “Parasols & Umbrellas”, cotton and haberdashery from Manchester and Staffordshire, “Corsets & Embroideries” from Paris. The most valuable exhibits were mining machinery such as Taylor Horsfield’s £850 “Air Compressor & Rock Borer”. “Bohemian Glassware” brought down from Sydney was valued at £600. The profits from this Exhibition were used to fund the sculpture known as the Gold Monument, which still gazes along Pall Mall (from the McCrae Street end). The Exhibition’s Cash Book shows payments, which totalled £1160, were made to then up and coming sculptor C.D.Richardson. Recently a City of Greater Bendigo staff member used both these volumes to write a detailed report about this monument, for Heritage Victoria.Carol Holsworth Collection: Small book Souvenir, 29 pages plus cover; each page. has a photo of the exhibit.

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.

This general purpose Multi-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 particular meter was manufactured in the Netherlands. This type of "old" analogue meter was replaced by digital meters whose electronic components are a fraction of the size of the older analogue ones.This analog General Purpose multi-meter is quite a large (for handheld mobile) 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 General Purpose Multimeter is an analogue meter i.e. it has a needle arm that moves across a scale of divisions. This is a large(hand held) device due to the mechanical movement system within and the large size of its electronic components of its circuitry.There are two black bake-lite push buttons operating the wire inserts Positive/negative leads at the top. The meter (protected with a glass window) has clearly marked graduations (top - volts, bottom amperes). Below this are two bake-lite dials (left "potentiometer the right one measuring range selector). Below this is a "dial" switch to input the desired resistance measuring range "V" Front "H&B ELIMA" and to the right Elavi 15n. 0n the front side is a label "STATE ELECTRICITY COMMISSION OF VICTORIA TRANSMISSION DEPT E.C.No." On the bottom of the base is a stenciled layout of the battery "layout" including the fuse .

This leather case holder for a general purpose Multi-meter( KVHS 0307 (A)) 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 particular carry case was manufactured in the Netherlands.

Multimeter, therefore it is made from thick leather. It has a carrying strap from a thick "D" chromed link. This link is fastened to the main cover by a looped leather strip with a black coloured rivet. All the fasteners are either chrome or black coloured rivets. The front, which when opened back exposes fully the inside of the case. It is clip fastened to the lower section of the front piece which also can be pushed back allowing the meter to be removed from the frontal position. There is a strip retaining strap slightly higher from the mid point. This is fasted by a black press stud. There are two "L" shaped tin protrusions allowing the meter to slide only down the case until it rests on these shelves. This provides for an empty space for minimal storage,.On the front bottom and below the clasp is a tag "STATE ELECTRICITY COMMISSION OF VICTORIA TRANSMISSION DEPT."sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth

This tester was used between 1950 and 1980's. As part of the Occupation, Health and Safety requirements, equipment used to monitor the performance of electricity producing generators, regularly, hand held testers were used to check the insulation and the "earth" pin were up the the required operational levels. As the generators and their ancillary monitoring equipment was spread over a large area and cumbersome to service small hand held devices were required. These had to always be safe for the user to operate. A selected range of high quality meters were recalibrated every two years in the Meter and Calibration Laboratory at Yarraville(near Melbourne) This meter is very significant to The Kiewa Hydro Electricity Scheme because it was an integral part of maintaining the electricity producing water driven generators of the power stations. The reason why this meter was so essential is that provided the safety check on equipment used to monitor each Hydro Generator that they were complying within the grid network parameters. Grid parameters are set so that if there is an electrical fault on the system, that fault can be attended to with a very small change in the output stability of each generator. It is essential that the voltage of the network remain within the set limits. Generators are at Dartmouth, Mackay, Clover, West Kiewa, Yarrawonga, Cain Curran and three Power Stations in the Thornton area.This hand driven current generator produces 500 volts by winding the handle(on funnel curved side) to keep the voltage constant(one minute per test). The whole body is made from caste aluminium. One of the functions of this meter is to test the isolation resistance of any equipment being tested. This is to see if that equipment is safe to handle(no electrical shocks). The second function is to test the earth pin of any portable electrical equipment. The turn key on one side can direct which function is required(marked insulation or continuity). On the top side(enclosed in a glass fronted marked scale) is a continuity scale(top) and an insulation scale(bottom). This is covered , when not in use by "flip up" lid with manufacturer's details and name of the instrument. Opposite the winder are two screw tight knobs. One marked earth(left side) and one marked line(right side). On the top and next to the glass windowed scales in a post manufacture SEC Vic equipment equipment ID number.

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 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.This heavy and thick all leather case for the "easy" transportation of the Volt meter recorder has a opening top which pop riveted to the main body(rivets are aluminium). 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

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
