During this phase, the system processes sensor readings (like vibration, temperature, and pressure) into statistical features such as RMS, kurtosis, and FFT bins <a href=\"https:\/\/medium.com\/intuz\/ai-powered-predictive-maintenance-roi-calculator-architecture-guide-da35f654f20c\" target=\"_blank\" style=\"display: inline;\" rel=\"nofollow noopener noreferrer\"><sup>[12]<\/sup><\/a>. This step ensures the data is in a format that machine learning models can work with effectively.<\/p>\n<p>Once the baseline is established, the system begins <strong>real-time scoring<\/strong>. Every 1\u201360 seconds, live sensor data is compared to the learned &quot;normal.&quot; If the reconstruction error surpasses a set threshold, the system flags it as an anomaly &#8211; even if the absolute values of the readings seem within acceptable ranges. For example, at a 310 MW hydroelectric station in 2026, continuous monitoring detected a rise in partial discharge from 200 pC to 840 pC over six weeks. Thermal imaging confirmed a hotspot 14\u00b0F higher than usual. This prompted a planned 9-day outage for stator rewedging, avoiding a replacement cost of $2.2 to $3.1 million and extending the generator&#8217;s life by 8\u201312 years <a href=\"https:\/\/oxmaint.com\/industries\/power-plant\/power-plant-predictive-maintenance-roi-case-study\" target=\"_blank\" style=\"display: inline;\" rel=\"nofollow noopener noreferrer\"><sup>[2]<\/sup><\/a>.

Keep the focus on numbers that resonate with the CFO&#8217;s priorities.<\/p>\n<h2>Related Blog Posts<\/h2>\n<ul>\n<li><a href=\"\/en\/predictive-maintenance-for-asset-management-infrastructure-and-real-estate-is-critical-use-the-web-site-the-web-sitehttpstheiamorg\/\" style=\"display: inline;\">Predictive Maintenance for Asset Management (Infrastructure and Real Estate) is critical &#8211; use the web site the web site:https:\/\/theiam.org<\/a><\/li>\n<li><a href=\"\/en\/how-predictive-maintenance-without-iot-and-real-time-brings-value-to-infrastructure-and-building-asset-owners\/\" style=\"display: inline;\">How predictive maintenance (without IOT and real time) brings value to infrastructure and building asset owners<\/a><\/li>\n<li><a href=\"\/en\/predictive-maintenance-and-roi\/\" style=\"display: inline;\">Predictive Maintenance &#038; ROI<\/a><\/li>\n<li><a href=\"\/en\/machine-learning-maintenance-realistic-expectations\/\" style=\"display: inline;\">Machine Learning in Maintenance: What You Can Realistically Expect<\/a><\/li>\n<\/ul>\n<p><script async type=\"text\/javascript\" src=\"https:\/\/app.seobotai.com\/banner\/banner.js?id=69f3f01fac8ee36f7cef4caa\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Utilisez l'apprentissage automatique pour d\u00e9tecter rapidement les anomalies des \u00e9quipements, r\u00e9duire les temps d'arr\u00eat et les co\u00fbts de maintenance, et prolonger la dur\u00e9e de vie des actifs.<\/p>","protected":false},"author":9,"featured_media":14548,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_seopress_titles_title":"Anomaly Detection for Predictive Maintenance","_seopress_titles_desc":"Use machine learning to detect equipment anomalies early, reduce downtime and maintenance costs, and extend asset life.","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"","footnotes":""},"categories":[1],"tags":[],"customer-name":[],"industry":[],"class_list":["post-14549","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"acf":[],"_links":{"self":[{"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/posts\/14549","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/comments?post=14549"}],"version-history":[{"count":1,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/posts\/14549\/revisions"}],"predecessor-version":[{"id":14584,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/posts\/14549\/revisions\/14584"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/media\/14548"}],"wp:attachment":[{"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/media?parent=14549"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/categories?post=14549"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/tags?post=14549"},{"taxonomy":"customer-name","embeddable":true,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/customer-name?post=14549"},{"taxonomy":"industry","embeddable":true,"href":"https:\/\/oxand.com\/fr\/wp-json\/wp\/v2\/industry?post=14549"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
