Choosing a PEL
You know you want one…
If you’re looking to cut your energy costs, you definitely should be interested in buying a PEL (portable energy logger). But beware, not all PELs are the same, says Julian Grant of Chauvin Arnoux. Follow his advice to choose a PEL that’s versatile, convenient and easy to use, and that will help you to access the full range of energy saving opportunities.
In any commercial or industrial electrical installation, there are numerous ways in which energy can be saved – or wasted. Just a few of the very common issues that are needlessly inflating business energy bills are unnecessary out-of-hours operation of equipment, inefficient lighting, unbalanced three-phase supplies, poor power factor and high levels of harmonics in the supply system. Action can be taken to address all of these issues, but before you can correct a problem, you need to know you have it!
So how do you go about identifying power supply problems? There’s the hard way, which involves taking a lot of measurements with multiple instruments of various kinds and then using a lot of time and expertise to analyse and interpret the results, or there’s the easy way, which is to use a portable energy logger (PEL).
