- Usage and application: Historically the Zellweger method of injecting a specific audio tone signal through medium voltage to low voltage mains to control receiving relays was a cheap and reliable method for supply companies to control load shedding applications for peak times for air conditioners, street lighting and other applications. Nowadays smart meters and electronics are used to function with these signals.
- This system often referred to as ripple injection, is not unique to Australia and is used elsewhere with other signal frequencies and systems. In Australia it is used for applications of load shedding and control in South East Queensland and NSW. The mains power is 230-250V at a frequency of 50hz and the ripple control signal is transmitted at a higher frequency that can be detected by smart meters or ripple signal detectors. The exact frequency of the ripple signal depends on your location and the system used by the energy operator in that area.
- In South East Queensland, for example, Energex use a 1050hz ripple signal. Elsewhere, such as NSW there is a mix of 1050Hz, 750hz and 492hz depending on location boundaries. (Note: these products are not suitable for use in the St George region that uses 492Hz) The advent greater use of electronic devices in the home has seen greater interference in everyday installations from the use in ripple injection. Back when incandescent lights were used, they would flicker a little during the ripple injection and then stabilize, however many electronic products require quality mains input signals and do not have filtering to cope with these higher frequencies through the standard sine wave and they react by flashing and losing control. The use of dimmers in the circuit can often increase the level of flashing or effects. Other products such as ceiling fans also suffer with the injected signals causing hum in the motors and fluctuations.
