What voltage optimisation levels can The Ark be set at?
The voltage optimisation of The Ark can be set at tappings of 6%, 8% or 10%. In Australia, the statutory minimum voltage is 216V, hence the voltage optimisation cannot be set to reduce the voltage below this level. Assuming a typical voltage of approximately 240V, an 8% tapping will reduce the voltage to approximately 221V. If the incoming voltage is higher than this, it is often possible to optimise the voltage by 10%, providing larger energy savings. The voltage at a site will generally fluctuate substantially over a 24-hour period. By measuring the voltage at 3-minute intervals over a 7-day period, we are able to get a very thorough understanding of the electricity supply quality delivered to a site, enabling us to set the appropriate voltage tapping level with regard to the statutory band.
