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.

What device converts AC to DC? rectifier A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current.

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 This model was produced in the time from 1933 to 1951 when it was superseded by the most popular model, Model 8 (1951 to 2008).This AVO meter brought the measuring of three electrical power indicators i.e., amps, volts and ohms into one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

When this AVOMETER leather case was being utilised in the early 1950's it contained 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 leather case which holds its AVO Meter brought the measuring of three electrical power indicators i.e., amps, volts and ohms into one measuring unit.

The speed of information on all "new technology" had a relatively slow assimilation rate to those living in rural communities. The use of solid leather carrying bags for transporting equipment up and down the mountains provided some form of protection against bumps and dust.This carry case for its AVO meter has an outer leather covering with an inner thick cardboard liner. The case has two mild steel buckles but stitched onto one side but no lid to fasten down. The sides are stitched together with strong tick twine. On either side there are small strap holds. On the bottom are four large chromed metal lugs acting as feet to keep the bottom from lying flat on any floor. The outside bottom has been branded "SOLID COWHIDE"Between the front two buckles is a identification plate riveted onto the cowhide "STATE ELECTRICITY COMMISSION OF VICTORIA ELECTRICAL ENGINEERING SECTION"electrical meters, electrical equipment, sec vic., state electricity commission of victoria, mount beauty, bogong village

A shock of different voltages was delivered to a person using the two metal handles or two heavy soft wire combs (missing but known of) were moved across the skin. Perhaps this was an early TENS Unit. The unit came to the donor's grandfather (Roy F. Leibig - Chief Electrical Inspector of the Brunswick (Melbourne) Electric Supply) for repair and returned to his keeping once it had become obsolete (upgraded by newer machine). Donor often helped his Pa repair electrical equipment.Historical: The Resuscitator or Electric Therapy Unit was used in hospitals, possibly Mental hospitals. Provenance: The donor worked at Mt Beauty in the Kiewa Hydro Electric Scheme with the State Electric Commission of Victoria as an electrician.
