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.

When this AVOMETER was being utilised in the early 1950's it was at the "leading" edge of electrical measuring instrumentation.The first meter was produced by Automatic Coil Winder and Electrical Equipment Co. in 1923. This model was produced in the time from 1933 to 1951 when it was superseded by the most popular model, Model 8 (1951 to 2008).This AVO meter brought the measuring of three electrical power indicators i.e., amps, volts and ohms into one measuring unit. By using a "one fits all" unit, the carrying of separate measuring devices was reduced considerably. The need for a mountainous and a large area of operational requirements, such as the SEC Vic Kiewa Hydro Electricity Scheme, to minimise the weight of equipment carried by electricians and technicians was of the utmost relevance. The significance of this meter to the Kiewa Valley region relates to the impact of modern technology (at that time) upon a mainly rural environment. This equipment shows how the boost of "modern" equipment into the area because of the "Hydro Scheme" was facilitated a lot faster than would have taken under "normal" evolutionary time. The speed of information on all "new technology" had a relatively slow assimilation rate to those living in rural communities. This AVOMETER is a Model 7 MKII, production pre 1951. This meter measures electrical Amps, Volts and Ohms and has two internal batteries for its power. The main casing is made from aluminium with a bake-lite front. The front has a "window" detailing, with a needle pointer, the amount of electrical power being tested. There are two big dial switches, detailing Direct Current(DC) and Alternating Current(AC) when reading measurements of Ampere, Voltage and Ohms for power. This meter took the place of three or four meters used earlier. Modern meters (2000 onwards) have become digilised and are considerably lighter in weight and smaller. There are two electrical connection leads (one black and one red) each has a removable clasp and is 125cm long.Molded on the front centre panel " UNIVERSAL AVOMETER". Below this and above the left hand dial "D.C. SWITCH" .Above the right hand switch the right "A.C. SWITCH". On the left of each switch is an arrow pointing to it.The left switch is marked with a "+" and the right one with a "-". There is a "divisional 2" mark. Between and below the dials is "CUT OUT" plunger.electrical meters, electrical equipment, sec vic., state electricity commission of victoria, mt beauty, bogong village

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. The back has four recessed screws and four small leather pads. There is a hole on each side to insert wires. There are two copper insulated wires.

Albion recorded a population of 4,334 at the 2021 census. Albion is bordered on the north by Ballarat Road, the south by Forrest Street, the west by Kororoit Creek and the east by Anderson Road. The suburb is completely surrounded by other parts of Sunshine except for Ardeer, which lies to Albion's due west across Kororoit Creek.History - The area was originally called Darlington, from at least 1860 to about 1890. The area originally known as Albion was directly west of Duke Street, as can be noted by the many streets there named after English counties and placenames – Albion being an ancient name for the island of Great Britain. Albion station opened on 5 January 1860 as Albion and Darlington but closed a year later. It was not until 1919 that a new station was opened on the same site with the name Albion station. In March 1885 the Albion Quarrying Company began its operations in the area. The disused Albion quarry, accessed from Hulett Street in Albion, was the location for AC/DC's Jailbreak music video. It was H. V. McKay of Sunshine Harvester Works fame who bought land to develop a residential community for his workers in first decades on the 20th century. His concept for Sunshine was the Sunshine Estate: a community designed with superficial similarities to garden cities of the early 20th century. This area was mainly in what is now called Albion. McKay's own residence, The Gables, was in Talmage Street (where the cul-de-sac The Gables now is) until it was consumed by fire and subsequently demolished. Today - Albion has many period homes such as California bungalows and 1940s weatherboard houses. In the eastern parts of Albion, many of the oldest homes were built by H. V. McKay as part of his Sunshine Estate, a housing community built according to the influential early 20th Century Garden city movement. Kororoit Creek provides the western border for Albion. Along it runs the Kororoit Creek Trail which runs all the way southwards to meet the Federation Trail in Brooklyn. Stony Creek lies on the eastern edge of Albion, close to Anderson Road. As of 2013, the creek's environmental state west of Anderson Road is very poor as it has long been converted to nothing more than a concrete stormwater drain for this particular section of its course. A notable landmark of Albion is the red brick John Darling and Son Flour Mill built in 1922. It is just to the south of Ballarat Road, next to Albion train station.7010.01 - 84 King Edward Avenue Albion Vic 3020 has a land size of 630m2.
