Unbalanced currents lead to torque pulsation, increased vibration and mechanical stress, increased losses, and motor overheating. Voltage and current unbalances could also indicate maintenance issues such as loose connections and worn contacts.<\/p>\n<p style=\"text-align: justify;\">Unbalance can occur at any point throughout the distribution system. Loads should be equally divided across each phase of a panelboard. Should one phase become too heavily loaded in comparison to others, voltage will be lower on that phase. Transformers and three-phase motors fed from that panel may run hotter, be unusually noisy, vibrate excessively, and even suffer premature failure.<\/p>\n\t\t<\/div>\n\t\t\t\t\n<style>\n#col-359769387 > .col-inner {\n  margin: 0px 0px -61px 0px;\n}\n<\/style>\n\t<\/div>\n\n\t\n<\/div>\n\t\t<\/div>\n\n\t\t\n<style>\n#section_1937517936 {\n  padding-top: 30px;\n  padding-bottom: 30px;\n}\n#section_1937517936 .ux-shape-divider--top svg {\n  height: 150px;\n  --divider-top-width: 100%;\n}\n#section_1937517936 .ux-shape-divider--bottom svg {\n  height: 150px;\n  --divider-width: 100%;\n}\n<\/style>\n\t<\/section>\n\t\n\t<section class=\"section\" id=\"section_777735909\">\n\t\t<div class=\"bg section-bg fill bg-fill  bg-loaded\" >\n\n\t\t\t\n\t\t\t\n\t\t\t\n\n\t\t<\/div>\n\n\t\t\n\n\t\t<div class=\"section-content relative\">\n\t\t\t\n<div class=\"row\"  id=\"row-188074907\">\n\n\t<div id=\"col-1301431225\" class=\"col small-12 large-12\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n<div class=\"container section-title-container\" ><h3 class=\"section-title section-title-center\"><b><\/b><span class=\"section-title-main\" style=\"font-size:150%;color:rgb(255, 194, 14);\">How to calculate voltage unbalance<\/span><b><\/b><\/h3><\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>\n<div class=\"row\"  id=\"row-313152020\">\n\n\t<div id=\"col-108545485\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_2118266897\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1020\" height=\"469\" src=\"https:\/\/techmaster.com.vn\/wp-content\/uploads\/2023\/11\/image.jpg\" class=\"attachment-large size-large\" alt=\"\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_2118266897 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t\n\t\t<\/div>\n\t\t\t\t\n<style>\n#col-108545485 > .col-inner {\n  margin: 24px 0px 0px 0px;\n}\n<\/style>\n\t<\/div>\n\n\t\n\n\t<div id=\"col-1972258055\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n<div style=\"text-align: justify;\">The calculation for determining voltage unbalance is straight forward.
