How it is works:
The nominal voltage of electricity supplied in Australia is supposed to be at 230V, however the acceptable range is between 217V to 253V. In a number of places, the voltage is significantly higher reaching 270V even.
Devices and in particular lights are usually designed to work within the voltage range of 220 - 240V. Voltage that is higher results in lower lifespan of electrical devices and increased power bills. More details
ES- reduce voltage to the optimum, and make all your lights and devices work within designed voltage.
