This transformer lamp system, which has a dial to transform 240 volts to a minimum of 32 volts was used by electrical technicians to inspect internal parts of the large generators (even in small confined spaces). The reason for the reduction of the 240 volts to the 32 volts was for the safety of the inspector. The SEC Victoria Hydro Scheme's electrical 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 the 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 transformer lamp is very significant to the Kiewa Valley as it was introduced as a very small 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 industrial and 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 is also a specific electronic item which was manufactured in Melbourne and not sourced from Europe or Asia. This demonstrates the fast evolution of Australian technology to a high standard compatible to that of the rest of the world.This heavy hand held electrical transformer (transforms 240 volts to 32 Volts) an has one leather handle on the top with three small (gauze filtered) air holes. It also has two 2 pin directional cable distribution (clipsal) in/out points 10amps / 240 volts. There is one glassed in volts/ac meter and one variable switch (180 to 150 voltage in settings of 10 volt increments.There are two vents (one on each of the smaller sides). There is also one three pin electrical lead coming out from the top.On one side is a manufacturer's plaque with "ELECTRONIC A & R EQUIPMENT MELBOURNE" and underneath "TYPE 1719, PRI V. 180 250" underneath "V.A. 1250" underneath "CYC 50" underneath "SEC V. 115" underneath "SEC A. 10 . 8".

Information from Norman F. Dalton: Ballarat had a reticulated DC supply in the early part of last century and in 1905 had sufficient generating capacity to enable the trams to be changed from horse drawn to DC electricity. The use of electricity increased with the main power station located on Wendouree Parade, near Webster Street, under the ownership of The Electric Supply Company of Victoria. AC generating plant was installed in 1925 and conversion to AC proceeded. In 1934 the company was taken over by the State Electricity Commission Victoria (SECV) and more AC generation was installed and the changeover of customers was accelerated. This is around the time that the Synchronome Frequency Checking Mast Clock was installed at the Wendouree Parade Power Station. The SECV Annual Report of 1921 states: ::Section 11 of the act directed the COmmission to enquire into the question of securing the adoption of such standards of plant and equipment of a system, frequency and pressure for the generation and distribution of electricity as will admit of the efficient interconnection of undertakings throughout the State. In 1934 when the SECV took over the Ballarat operations the question of linking with the State grid had been a planned operation for some years but due to financial considerations had hindered it and in fact would continue to do so for a further 10 years. So while the need for close frequency control for interconnection was hardly an issue, the need to keep electric clocks correct was important, particularly as this item was a frequent sales point to cover the inconvenience and sometimes expense of converting from DC to AC. The clock is a very accurate pendulum clock with provision for varying effective length during operation for precise time regulation. There are two normal time dials and one is controlled by the pendulum and the other is operated by the system frequency. When the clock was in use it was installed by the MEter and Tests Laboratory and the time was checked daily by radio time signals. The two dials were repeated in the operators control panel in the Power Station. A maximum deviation between the two dials was set in the operating instructions (eg 5 seconds) and the operator would correct this when necessary by remote manual alteration of the turbine governor set point. The clock was used to drive and regulate a system of "slave" clocks which were used to display the time in various locations around the power station. A slave clock is a simple clock which is driven by a small electric motor, its accuracy is regulated by the master clock every 30 seconds to ensure that it and all the other slave clocks in the station are on exactly the right time; slave clocks were placed in various locations, from common rooms to workshops. A master clock could potentially run thousands of slave clocks at one plant. The clock also contains a rectifier. A rectifier is a device that is used to convert AC power to more stable DC current.Two clocks in a timber case. Both are electric, one is powered by the main pendulum mechanism, the other is a self contained electric clock. The main mechanism is of the gravity arm and roller type, which sends an impulse to the slave clocks every 30 seconds. The This Synchronome Frequency Checking Master Clock was used at the Ballarat Power Station. Below the main section of the case is a smaller cabinet containing a rectifier to provide consistent DC power for the clock. The rectifier was made by the Victorian company Hilco, which was located in Burwood. There is a high chance this is not the original rectifier from this clock as there appears to be brackets to hold a larger device in the space the rectifier occupies.Front below main clock face on front of case: "Patented Sychronome Brisbane" Lower left-hand clock face: "Frequency time" Lower right-hand clock face: "Standard Seconds" Synchronous electric clock mechanism on door (Frequency time clock): >200/250 V. 50~ >"Synchronomains" Made in England >Direction indicator for clock starting switch >"To start move lever in direction of arrow and release" >"Patent applied for" Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for main clock face: >"English Made" >"Patented" >Serial number "8751" >0 above right-hand pillar on front-plate Inside case, back panel, top enamel plate: >Seconds Battery + Pos. > Battery Common or - Neg. >1/2 min dials Inside case, back panel, bottom enamel plate: external seconds dial Inside case, right hand side, electrical knobs: two switches, both "A.C. mains" Pendulum rod, below suspension spring: Serial number (?) 0000005 Rectifier in bottom cabinet: >"Hilco Rectifier" >"A.C.

This resistor was part of the Hydro generator control metering system which displays what electricity is produced at the underground generators. The control centre can be hundreds of meters above the generators and this resistor reduces the large current to a small voltage entering a calibrated control monitor. This resistor is highly significant to the Kiewa Valley because it represents a major construction and ongoing operational industry dealing with the supply of hydro electricity to Victoria. Although it is relatively small in size it is part of the controlling mechanism for the supply of a non polluting energy source for home and industrial use.This mainly metal and wire resistor has been built of copper and brass and designed to carry a current of 2000 Amperes. Wires are wound around a non conductive cement block which has grooves on the top and bottom ledges to hold the wires snuggle into place. At the rear there are three connection rods which have long 5mm thick screws (to fasten cable ends)On one side it is scribed "0.2 OHMS" and underneath this "10 AMPS"kiewa hydro electricity scheme, victorian state electricity commission, transformers
