Protective relays are one of the critical components of the elctrical power grid that serve to detect defective equipment or other dangerous or intolerable conditions and can either initiate or permit switching or simply provide an alarm to provide an alarm to provide a safer, more reliable delivery system. Used in power stations. The function of relay is to quickly remove from service any equipment that might suffer damage or otherwise affect the operation of the system. Relays protect the electrical system in 2 ways: Prevent failure or damage to electrical systems. Mitigate the effects of failure when it occurs. Switches that control other switches. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal.Used by the State Electricity Commission of Victoria for the Kiewa Hydro Electric Scheme in the power stations. Manually operated by remote control for an external circuit breaker. The relays were from a Kiewa Hydro Power Station control panel.Collection of black metal rectangular boxes (heavy) containing electrical wires forming a circuit. The longer, narrower rectangles have a bakelite knob at one end. Some of the boxes have one side of clear perspex and another has all sides of clear perspex. One is labelled "group relay". Another has windows with labels eg. 'turbine overspeed' 'emergency trip' and one has 3 steel knobs. - with 'stop', 'start'. One box is larger than the rest and has clear perspex side showing 'overcurrent relay' and workings.One has a plaque attached. Manufacture: "The English Co. Ltd.

The box is cleverly designed to give quick access to the parts inside, having a lift-up lid and a pull-down front. The components within appear to be a portable radio, power supply or power converter with batteries and a charger. The attached leather strap makes the equipment easily portable. The portable power supply is significant for representing part of the evolutionary change in communications. The unit connects the use of power and radio for communication with the ability to save the power in power packs or batteries, or to convert the power from one form to another.Power supply, portable, electric; circuits can be Parallel or Series. Batteries (6) fitted into a square wooden box. Box has two catches to secure the lid and two catches to secure the drop-down front.

The Ferranti Sirius is an electronic second-generation transistor computer and is one of three remaining examples of this machine left in the world. It was an important addition to the computing facilities at Monash University in the early 1960s and provided access for computer programming and research for many early computer professionals, academics and teachers. The Ferranti Sirius computer was built in a period of rapid growth in computing technology. The first stored program computers appeared in the late 1940s and used individual designs with valve technology. By the mid-1950s valve technology was replaced by transistors and the first mass produced commercial computers became available. The Ferranti Sirius was announced in 1959 and offered a “small” academic computer. It was designed and built by the English company Ferranti Ltd and sold through a local office of the company in Melbourne. The Sirius was manufactured at the Ferranti Ltd.’s West Gorton, England factory from 1959 to 1963 and, in all, the company produced probably 22 installations although only 16 were actually recorded as sold; this included one at Ferranti’s Bureau in London and one at Ferranti’s Melbourne Bureau. Only 7 were exported and 4 of these 7 were located in Melbourne, Australia. All four were associated with computing at Monash University – the Sirius in the MMoCH collection was purchased by Monash University in 1962, a smaller Ferranti Sirius was used on the Caulfield campus (prior to amalgamation with Monash University) from 1963, the Ferranti company had its own Ferranti Sirius initially temporarily installed at Clayton campus in 1962 and then placed in their office in Queens Road, Melbourne. A fourth computer was purchased by ICIANZ (now Orica) in 1962 and was transferred to Clayton campus in 1967. Only two of these Melbourne examples have survived; one in the MMoCH collection and one at Museums Victoria. There is an example of the Ferranti Sirius in the Science Museum Group collection in the UK as well. The Ferranti Sirius in the MMoCH collection was the first computer purchased by Monash University and it was shipped to Australia to be installed by November 1962. The University had a similar model computer on loan from Ferranti Ltd during the first part of the year and it was returned to the office of the company in Queens Road, Melbourne once the University’s own machine was installed. The computer was placed on site at Clayton campus, Monash University. The computer operated from 1962 until 1972 when it was officially decommissioned. The Ferranti Sirius was sold to Mr Paul Stewart in late 1974 and removed from Monash University. Mr Stewart later donated the computer back to the University in 1988 and it was transferred to the collection of the Monash Museum of Computing History after 2001. The Ferranti Sirius is an electronic second-generation transistor computer and is one of three remaining examples of this machine left in the world. It was an important addition to the computing facilities at Monash University in the early 1960s and provided access for computer programming and research for many early computer professionals, academics and teachers. The Ferranti Sirius is of scientific (technological) significance as one of the early transistor digital computers that transitioned computing from first-generation valve computers to second generation commercial installations. This example of the Sirius is of historical significance in its role as a part of the Computer Centre, Clayton campus, Monash University which provided computing facilities in Melbourne in the early 1960s when there were few installations available for academic, administrative and commercial users. Staff and students were able to undertake investigative research and learn programming techniques. The Computer Centre encouraged the use of the computer across all disciplines and this provided the base to establish computer science as a subject offering and, later, a new department in the University. This growth in computer education eventually culminated in the establishment of the Faculty of Information Technology, Monash University. The Ferranti Sirius in the collection at Monash Museum of Computing History has a main unit with a CPU and memory combined with input/output equipment and one extra cabinet of memory. The Central Processing Unit is a floor-standing unit which contains the computer circuits, power supplies and has a decimal digit display panel and a normal clock. A moveable control panel is placed in front of the Unit (Currently set on a recreated desk/filing cabinet support in the display). The Sirius base unit uses acoustic delay line memory with 1000 word store. An additional 3000 word memory cabinet is set adjacent to the CPU and can be connected to increase the memory. The computer is supported by a range of input/output devices. There is a Ferranti Paper tape reader, located on desk in front of CPU. Red label on front “Ferranti tape reader. Type TR 5. Serial No. 477”. Adjacent to the CPU is a set of Simplified tape editing equipment in three pieces which includes a (1) Table unit with switches on front face. Metal tag on reverse reads “Creed & Co. Model No. S4060. Serial No. 1457. Original Customers Marking GRP7 V706”. The table has a numbered internal tag “Table Serial No. 198579. (2)Creed teletype set on table unit. Metal tag on reverse “Creed & Co. Model No. 75RPR K4M4. Serial No. 5897 Made in England”. (3)Creed paper tape reader set on table unit. This set of equipment could read paper tape and print it, or copy paper tape while allowing it to be edited, or allow a programmer or data preparation person to type and punch a new program or data. It has no electrical connection to the computer. Paper tapes were usually torn off and carried across to the computer. There is also another table unit with switches on front face and changeable setting switch on front right side which holds a Ferranti Westrex paper tape punch set. Label on reverse “Teletype Code BRPE11” This was the Computer’s only output device. BRPE-11 is a teletype model number.

Although the Kiewa Hydro-Electric Scheme was first proposed in 1911, construction did not commence until 1938. As part of the push to cut electricity costs and diversify supply, the Victorian Government (circa 1930) initiated the conversion from primarily brown coal supply to hydro – electricity. Field investigations during the 1940’s resulted in a new proposal for a scheme that had more than double the capacity of the 1938 scheme. The Kiewa Hydroelectric Scheme became the largest scheme of its kind in the State Of Victoria and the second largest scheme in Australia. The number of personnel involved in the planning and construction of the scheme increased dramatically. During the late 1940’s, most activity centered around the construction of the West Kiewa Power Station, Rocky Valley Reservoir, McKay Creek Power Station and the Bogong Creek Aqueduct.A common thread across all the larger hydro scheme constructions was the need for workers, both qualified and unqualified who came from around the world seeking a new life for themselves and their families. New accommodation and facilities were required for the army of workers engaged in construction in often remote and wild areas. The SEC had a high demand for timber, and set up the first of a number of sawmills at Bogong Creek in 1939 and set up the first hardwood logging in the headwaters of the Kiewa River. These new ‘towns’ such as Mt Beauty and Bogong, survived, serving the needs of operational personnel and their families, and expanding with growth of new industries. Mount Beauty, and to a lesser extent Bogong, are among these places.

Megger as the device was called, is in fact its brand name. It is a device that supplies a DC (direct current as per car batteries) voltage to enable testing of electrical apparatus. This particular device produces 250volts DC when the handle is turned vigorously. If an electrical device, such as a kettle or toaster, blew a fuse or tripped a circuit breaker, when switched on, then it must be checked electrically before any more use. Following the repair of the faulty item a megger would be used to check if either of the AC 240volt plugs leads were touching the metal case (earth). The output leads of the megger would be connected with one to the earth (metal case) and the other to each of the power connections in turn. A good megger reading of 50,000 ohms (resistance) would enable the device to be returned to service. A reading of zero ohms resistance would mean that it would again blow a fuse, and was therefore unsafe to use. In the electrical industry e.g. the former State Electricity Commission, a megger would be used to test lots of similar item in sequence. Because of the vigorous job of winding the handle, two persons were often used to save time. One would crank madly whilst the other shifted the leads. This particular megger is of a small voltage, but other meggers are bigger and have a few ranges of DC voltages able to be selected. The optimal megger for large Generating machines was motor driven megger. This was applied to the device being tested for a duration of approximately 30 minutes with reading of the resistance taken at regular intervals.All equipment belonging to the State Electricity Commission of Victoria was labelled with a metal plaque attached to it. The SECV constructed the Kiewa Hydro Electric Scheme in the Upper Kiewa Valley and on the Bogong High Plains. The scheme began in 1938 and finished in 1961 when this megger was used and also possibly later as the SECV remained to maintain and operate the Scheme. This megger is of significance in relation to the advancement of technology.A rectangular box in dark brown bakerlite casing. It has an agent's plaque fixed to the left of the face and on the right is the marker's recessed stamp. In the middle in a transparent window so the level of ohms can be read. The front also has two recessed fixing knobs in black. On one side is a crank handle with a knob that lifts up and is turned vigorously to create the voltage.

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

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.

DEFINITION microfarad Posted by: Margaret Rouse WhatIs.com Contributor(s): Kenda, Jack Clements The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad. The microfarad is a moderate unit of capacitance. In utility alternating-current (AC) and audio-frequency (AF) circuits, capacitors with values on the order of 1 µF or more are common. At radio frequencies (RF), a smaller unit, the picofarad (pF), is often used. This unit is equal to .000000000001 (10^-12) µF. In RF scenarios, capacitances range from about 1 pF to 1,000 pF in tuned circuits, and from about 0.001 µF to 0.1 µF for blocking and bypassing. At audio frequencies (AF), capacitances range from about 0.1 µF to 100 µF. In power-supply filters, capacitances can be as high as 10,000 µF. Capacitor, 1/3 M.F.D.

In March 2024, Milissa Box (DTP) was at a trash and treasure market. She'd found a $5 photo album for sale with some photos that she thought might be of interest… From what I can gather it belonged to the gentleman pictured who was a worker at Dandenong in the Comeng and ABB eras. He appears to have worked on the Z3, A1/A2, B1/B2 class trams, Hong Kong LRVs, Comeng Melbourne suburban trains, and later the extra Victorian-purchased XP power cars and XAM sleepers to enable the Riverina XPT to be extended to Melbourne. It's clear he was very proud of the vehicles he'd helped to build. I have scanned a selection of the images, which appear to be a mix of official builder's portraits, team photos, and self-taken shots showing candid everyday scenes on the shop floor. There are also images of the launch of the XP power cars with then-Victorian Premier Joan Kirner; and some personal visits to see the Flying Scotsman, Victorian Goldfields Railway, Coal Creek, etc. Filename Description Date Comeng Scans 2024-03-05 0001 Three Comeng workers (including the photographer) stand in front of Comeng suburban train 697M (Chopper unit) c.

The Optacon OPtical-to-TActile-CONverter is a compact, portable reading aid for the blind. It is about the size of a textbook, and weighs less than 2kg. It works by converting a printed image into a tactile image that a blind person can feel with one finger. After a period of training and practice, a blind person can use the Optacon to read ordinary books, magazines, newspapers, and other printed materials. The Optacon was developed after intensive research at Standford University, California, USA and was trialed by clients of the Royal Victorian Institute for the Blind (now part of Vision Australia) in 1973. It has three main sections: 1 a miniature camera, 2 an electronics section, and 3 a tactile stimulator array. The miniature camera, about the size of a pocket knife, is mounted in a housing that has rollers for easy movement along a line of print. The camera is connected to the electronics section by a lightweight cable. The electronics section and the tactile stimulator array are in the main chassis. The array consists of 144 tiny metal rods arranged in six vertical columns and 24 horizontal rows. Each of the rods can vibrate independently. The tips of these rods protrude through holes in a concave finger plate where the index finger is placed flat in order to read. These three components act together to convert the image of a printed letter or other shape into a pattern of vibrating rods, a tactile image of the letter or shape. The letter shape is tactually perceived as an image that moves from right to left on the finger, showing the left or leading edge of the letter first. Letters are felt sequentially rather than all at once, and the image should be kept moving. The Optacon converts a printed O into a tactile form that resembles a crater with a vibrating rim -- a completed circle. C would have a gap or opening on the right side of the curve. The letter F would be felt, sequentially, as a vertical line with two trailing horizontal lines. Because it can convert any ordinary printed image into a corresponding tactile image, the Optacon is not restricted to any special typestyle or language. The camera has a zoom lens that compensates for differences in the size of type. The standard Optacon lens can accommodate type sizes from 6 point to 20 point. With the optional F4A magnifier lens, type sizes as small as 4 point can be read. Powered by a rechargeable battery, and comes with its own battery charger. The battery is contained within the main chassis, and is not removable by the user. There are four basic controls on the Optacon: the Magnification Adjustment zoom button located on the camera section on the side opposite the rollers; and the On-Off switch, the Stimulator Intensity Adjustment knob, and the Threshold Adjustment knob located on the right side of the front panel. The Circuit Breaker protrudes from the right-hand wall inside the chassis compartment. From left to right when the back panel is facing you, are located: the jack for connecting the battery charger; the Battery Check button; the Normal-Invert switch; and the Input/Output I/O connector for use with the Visual Display, when using the Repeater Cable to connect two Optacons to one another or with other accessories. Designed not be removed from the leather case during normal operation, the On-Off switch is a slide switch located on the right side of the front panel. It slides up and snaps into place in the on position. 1 black with orange front, rectangular device in leather case assistive devices, audio equipment

Used to communicate with the local telephone exchange and for connection to other subscribers. The introduction of automatic exchanges saw the their demise. This phone was used in the family home of the donor at Caboolture (aboriginal for carpet snake) during the 1940s and 1950s.A magneto telephone for communication with a manual telephone exchange. The handle on the right hand side, which was turned to rotate the magneto to call the exchange - ask operator for a number and then to be connected. Telephone enclosed in a specially designed box for mounting on the wall. There was a bell on top which rang when the magneto ringer at the exchange was turned. Fitted with a carbon microphone mounted on the front of the box for the transmission of the spoken word and an electro- magnet. A receiver which hangs on the left hand side on a hook. The hook acts as the on and off switch to answer the call and to switch on the battery to provide power for the receiver and energize the transmitter. There is an angled ledge for writing any messages. There is no battery.
