And this is where the shoe can sometimes wriggle.<\/h4>\n<p>In a manufacturing environment, a strategy can only work if there is enough knowledge and experience to support the vision, but sufficient ROI must also be realised to ensure that everything is worthwhile. But as for Industrial Energy Wastage, there is no research institute anywhere where an industrial plant manager can go to determine what is \u201creasonable\u201d energy consumption in a production facility. So how can one then assess what part of the current energy consumption is reasonable and what part is wasteful, or what part of that wasteful part provides enough efficiency to justify intervention?<\/p>\n<p>The return we are talking about here includes the cost per kWh charged by the power company. The rates of these vary, depending on the time of day and time of year. Reducing these costs also leads to immediate cost savings. The investment consists of the material and labour required to change the energy consumption. The return is the period of time that must pass before the lower energy bill leads to the creation of returns. What remains after the costs have been paid is then the icing on the cake.<\/p>\n<p>If we then look again at the strategy, how can we estimate how much return these interventions are going to generate if there is no industry standard for reasonable energy consumption against which to measure it?<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<div class=\"vc_empty_space\"   style=\"height: 64px\"><span class=\"vc_empty_space_inner\"><\/span><\/div>\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h4>Profiling Industrial Energy Waste<\/h4>\n<p><a href=\"https:\/\/lhm-instrumentation.eu\/en\/product\/fluke-1732-1734-three-phase-electrical-energy-loggers\/\">Energy consumption<\/a> in the industry varies and this is due to several factors:<\/p>\n<ul>\n<li>the age of the factory<\/li>\n<li>the type of load and its format<\/li>\n<li>operating schedule, both hours per week and intensity of load<\/li>\n<li>the number of employees<\/li>\n<li>climate<\/li>\n<li>the maintenance philosophy.<\/li>\n<\/ul>\n<p>The answer to this question is: don't try every <a href=\"https:\/\/lhm-instrumentation.eu\/en\/product\/fluke-1736-power-quality-logger\/\">kW to manage<\/a> consumed by your facility. These are the \u2018knowledge and experience\u2019 in the equation. Divide the facility by electrical infrastructure and then by key systems.<\/p>\n<p>Energy conservation starts with two basic tactics: (1) general inspection of key systems and (2) targeted data collection, including logging energy consumption at main service inputs and at key load points.<\/p>\n<p>Establish what the specified consumption of a system is and how much the system currently consumes. In addition, establish how much waste is occurring (either in terms of hours and type of use of the system or in terms of equipment and the system itself). To realise the savings, this waste needs to be addressed in the facility, through changes in procedures, maintenance or equipment and controls.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<div class=\"vc_empty_space\"   style=\"height: 64px\"><span class=\"vc_empty_space_inner\"><\/span><\/div>\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-7932 size-full\" src=\"https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling2-e1692262118648.jpg\" alt=\"\" width=\"198\" height=\"179\" srcset=\"https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling2-e1692262118648.jpg 198w, https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling2-e1692262118648-100x90.jpg 100w\" sizes=\"auto, (max-width: 198px) 100vw, 198px\" \/><\/p>\n<h4>Energy components<\/h4>\n<p>Before we start looking at how to <a href=\"https:\/\/lhm-instrumentation.eu\/en\/product\/fluke-1770-series-three-phase-power-quality-analysers\/\">be able to track energy consumption<\/a>, we will take another look at how we define and measure energy.<\/p>\n<p>Energy can be expressed in terms of real, reactive and apparent power (<strong>Figure 1<\/strong>).<\/p>\n<p>The flow of energy is described as:<\/p>\n<ul>\n<li>actual (P) or active power in watts (W)<\/li>\n<li>reactive power (Q) in volt-amps reactive (VAr)<\/li>\n<li>complex power (S) in volt-amps (VA)<\/li>\n<li>apparent power, the size of complex power (VA)<\/li>\n<\/ul>\n<p>The mathematical relationship between real, reactive and apparent power can be represented by vectors or can be expressed by complex numbers, S = P + jQ (where j is the imaginary unit).<\/p>\n<p>Reactive power does not transfer energy - it does not produce labour - and is thus represented as the imaginary axis of the vector diagram. Real power moves energy, so this is the real axis.<\/p>\n<p>The speed of energy flow in a system depends on the load - is it resistive, reactive or both?<\/p>\n<p>With a purely resistive load, voltage and reverse polarity of current simultaneously, the product of voltage and current is positive at all times and only real power is transferred: labour is produced.<\/p>\n<p>If the load is purely reactive, the voltage and current are out of phase and the product of voltage and current can be positive or negative. This indicates that part of the energy is transferred to the load and part of it flows back. The net transfer of energy to the load is zero: no work is produced.<\/p>\n<p>In reality, all loads include a combination of resistance, inductance and capacitance, creating both real and reactive power in a system. Therefore, electrical systems are designed to tolerate a certain amount of reactive power. Problems arise when too much reactive power is generated. Not only is there not enough real power to produce the required labour, but even the system's overall capacity to generate labour is compromised. This is also why utilities fine their customers if their loads produce too much reactive power: it is wasted power because it costs money to generate it, but it cannot be used. Most utility bills count VAr (reactive power) and on many they also calculate the power factor, where the power factor is an indication of how much a system has dropped relative to 100 per cent actual power. Most utilities require their customers to stay above the 0.95 PF (Power Factor) limit.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><a class=\"maxbutton-7 maxbutton maxbutton-plan-een-consultatie\" target=\"_blank\" rel=\"noopener\" href=\"https:\/\/lhm-instrumentation.eu\/en\/contact\/\"><span class='mb-text'>Schedule a consultation<\/span><\/a><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<div class=\"vc_empty_space\"   style=\"height: 64px\"><span class=\"vc_empty_space_inner\"><\/span><\/div>\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h4><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-7934 size-full\" src=\"https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling3.jpg\" alt=\"\" width=\"299\" height=\"187\" srcset=\"https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling3.jpg 299w, https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling3-200x125.jpg 200w, https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling3-100x63.jpg 100w\" sizes=\"auto, (max-width: 299px) 100vw, 299px\" \/>Monitoring energy consumption<\/h4>\n<p>By understanding the basic components of energy, an electrician can <a href=\"https:\/\/lhm-instrumentation.eu\/en\/products\/electric\/energy-and-power-quality-meters\/\">equipment for logging energy consumption<\/a> set to measure the overall level and quality of consumption and then track when energy is consumed and by what.<\/p>\n<p>Log power at main and secondary panels and at large loads.

Even a peak consumption of just a few minutes can increase the utility's tariff for several hours, days or even weeks.<\/p>\n<p>By scheduling the use of taxes differently, a company can take advantage of times when energy is cheaper. See how far below \u20181\u2019 the power factor is and check the power company's bills to see if there are deductions for a bad power factor. If so, the Power Logger can help trace the sources. After making changes in the necessary power areas, reconnect the logger to check that you are indeed benefiting from these efficiency improvements.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<div class=\"vc_empty_space\"   style=\"height: 64px\"><span class=\"vc_empty_space_inner\"><\/span><\/div>\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-7935 size-full\" src=\"https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling4.jpg\" alt=\"Detecting industrial energy waste\" width=\"299\" height=\"224\" srcset=\"https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling4.jpg 299w, https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling4-200x150.jpg 200w, https:\/\/lhm-instrumentation.eu\/wp-content\/uploads\/2023\/08\/energieverspilling4-100x75.jpg 100w\" sizes=\"auto, (max-width: 299px) 100vw, 299px\" \/><\/p>\n<h4>Knowing where energy waste occurs<\/h4>\n<p>Every system and process can be a source of waste and this needs to be contained or eliminated.
