It goes without saying that ‘The Public Sector Decarbonisation Scheme’ is laudable in its objectives, as the world as a whole is dealing with an unprecedented ecological crisis. However, perhaps the first thing facilities managers should invest in when looking to improve energy efficiency is an instrument that allows them to accurately measure and record energy usage. Having an initial benchmark – before embarking on any changes and upgrades – is essential for measuring improvement and progress through time.
A portable energy logger (PEL) like the Chauvin Arnoux PEL103 is the ideal tool for accurately monitoring power consumption and much more, including harmonic levels, voltage imbalance and power factor. In addition, by using a PEL103 across entire buildings and recording the results over time, facilities managers will be able to gain detailed and revealing insights into what’s actually contributing to their energy bills.
A PEL is an all-in-one instrument that measures a whole range of electrical parameters, such as voltage, frequency, current, real power, reactive power, harmonic levels and more. Crucially, the PEL doesn’t only measure these parameters, it also stores the results over a period of time that can range from a few minutes to months. This is essential, as some key issues, like equipment that is not needed during the shutdown but is still switched on and off automatically by a timer, can only be identified by looking at time-stamped energy usage records.
