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.

After the 1939 bushfires, the Forests Commission Victoria invested heavily in a radically new communications network. After suffering some inevitable delays due to the war, radio VL3AA switched into full operation in October 1945 proudly beaming out 200 watts across the State. But by today’s standards, the technology was primitive and the reception poor unless the user was on a high point somewhere. The radio signal was "line-of-sight" and bounced between fire towers and relay transmitters across the mountains back to the District offices. The advent of solid-state electronics in the 1960s replaced the more delicate valve sets which enabled greater use of vehicle mounted radios. The Commission continued to research, develop and build new radios at its many workshops around Victoria. The network was supported by a large team of skilled radio technicians. The more secure and versatile State Mobile Radio (SMR) digital trunk system came into operation in about 1995. Upgraded Tait Radios were purchased in 2014 after recommendations of the 2009 Bushfires Royal Commission. But it was the convergence of separate technologies such as 5G mobile phones, high-capacity and light-weight lithium batteries, Wi-Fi, the ever-expanding internet, cloud data storage, digital cameras, GPS, personal organisers and hundreds of supporting Apps into powerful smartphones and tablets which revolutionised bushfire communications from the mid-2000s.

An induction coil consists of two coils of insulated copper wire wound around a common iron core. One coil, called the primary winding, is made from relatively few (tens or hundreds) turns of coarse wire. The other coil, the secondary winding, typically consists of many (thousands) turns of fine wire. An electric current is passed through the primary, creating a magnetic field. Because of the common core, most of the primary's magnetic field couples with the secondary winding. The primary behaves as an inductor, storing energy in the associated magnetic field. When the primary current is suddenly interrupted, the magnetic field rapidly collapses. This causes a high voltage pulse to be developed across the secondary terminals through electromagnetic induction. Because of the large number of turns in the secondary coil, the secondary voltage pulse is typically many thousands of volts. This voltage is often sufficient to cause an electric spark, to jump across an air gap separating the secondary's output terminals. For this reason, induction coils were called spark coils. The size of induction coils was usually specified by the length of spark it could produce; an '8 inch' (20 cm) induction coil was one that could produce an 8 inch arc. (http://en.wikipedia.org/wiki/Induction_coil)A metal and plastic object on a timber stand. In an induction coil the distance between the plates is often used to measure the voltage of the spark since the air breaks down at 30 000 volts per centimetreballarat college of advanced education, scientific instrument, induction coil, scientific instruments, electricity

Motorola introduced the Bag Phone in 1988. These phones offered more durability and higher power output (up to 3 watts) than more conventional mobile phones of the time. Bag Phones were expensive to purchase and operate. They became available within the Department in the early 1990s but their use was very restricted to staff like fire communications duty officers. Senior regional managers also had bag phones. Bag Phones were also bulky and heavy and were often known as "The Brick". The 12 volt sealed lead-acid rechargeable battery provided up to 2.5 hours of talk time and 48 hours of standby time. They were replaced from the mid 1990s by smaller, analogue flip-phones with lighter Nicad batteries manufactured by companies like Nokia. The mobile phone network was patchy in country Victoria where two main telecommunications companies operated - Telstra and Optus.Motorola Bag Phone with handsetOptus 018 594 510 No battery Includes handset, aerial and 12 volt car-charger jack in vinyl bagforests commission victoria (fcv), communications

Differing gauges of transmission line was/is used in the Kiewa Hydro Electric Scheme. Some carried 330KV, 220KV, 66KV (Mount Beauty to Bright) and (Clover to Mount Beauty) and 22KV. All the cables have a core of steel for strength and an aluminium outer layer for transmission. Examples include 66KV copper cable, copper earth wire from the towers, copper cable found along the aqueducts for telemetering and copper earth wire. The 24 Volt Communication cables were/are used for linking different sites on remote SEC equipment.The State Electricity Commission of Victoria constructed the Kiewa Hydro Electric Scheme during the late 1930's to 1960's.

The cables No.s 1 to 9 have a core of steel for strength and an aluminium outer layer for transmission. The copper cables No.s 10 - 14 are used for earthing and are in the ground as copper doesn't rust or corrode (steel does). Copper is three times heavier (dense) than aluminium. Each of the outside aluminium wires are wound in the opposite direction so that when the cable is stretched under load, they tighten.state electricity commission of victoria. kiewa hydro electric scheme. cable. communication. transmission. telemetering. power. electricity.
