And this would be right in the principle. However, the final decision will depend on several installation criteria which is related to:<\/p>\n<ul>\n<li>Economical interest \u2013 the cost of the solution<\/li>\n<li>Engineering simplicity \u2013 the efforts to evaluate this solution and to commission it<\/li>\n<li>Maintenance easiness \u2013 which is also related to the cost of the maintenance<\/li>\n<li>Footprint<\/li>\n<li>Weight<\/li>\n<li>Energy saving \u2013 the possibility to reduce energy consumption for some applications, for example when the operation is integrating idle cycles or reduced flow rate<\/li>\n<li>Flexibility of adaptation \u2013 for varying operational conditions of flow, pressure, operating cycle<\/li>\n<\/ul>\n<p>The next table provides a relative comparison of the above solutions for these installation criteria. It shows that the basic, contactor-based starting methods are also the most cost effective and easier for maintenance; but from the previous table we can see that these also cause the most stress on the network and the load:<\/p>\n<p> <img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-53808\" src=\"https:\/\/blog.schneider-electric.com\/wp-content\/uploads\/2019\/01\/Image-2-d.png\" alt=\"\" width=\"1054\" height=\"388\" srcset=\"https:\/\/blog.schneider-electric.com\/wp-content\/uploads\/2019\/01\/Image-2-d.png 1054w, https:\/\/blog.schneider-electric.com\/wp-content\/uploads\/2019\/01\/Image-2-d-300x110.png 300w, https:\/\/blog.schneider-electric.com\/wp-content\/uploads\/2019\/01\/Image-2-d-768x283.png 768w, https:\/\/blog.schneider-electric.com\/wp-content\/uploads\/2019\/01\/Image-2-d-1024x377.png 1024w\" sizes=\"auto, (max-width: 1054px) 100vw, 1054px\" \/> <\/p>\n<p class=\"Normal1\" style=\"margin-bottom: 10.0pt\"><span style=\"font-family: 'Calibri',sans-serif\">You can find more information about large motor starting in the PCIC Conference <a href=\"http:\/\/www.pcic-europe.com\/images\/stories\/docs\/2017\/EUR17_60.pdf\">tutorial here<\/a>. <\/span><\/p>\n<p class=\"Normal1\" style=\"margin-bottom: 10.0pt\"><span style=\"font-family: 'Calibri',sans-serif\">Learn more about motor management <a href=\"https:\/\/www.schneider-electric.com\/en\/work\/solutions\/system\/s1\/motor-management.jsp\">here<\/a>.<\/span><\/p>\n<p>The post <a rel=\"nofollow\" href=\"https:\/\/blog.schneider-electric.com\/oil-and-gas\/2019\/01\/08\/large-motor-starting-103-motor-starting-methods-how-to-choose-the-right-one\/\">Large Motor starting 103: Motor starting methods \u2013 how to choose the right one<\/a> appeared first on <a rel=\"nofollow\" href=\"https:\/\/blog.schneider-electric.com\">Schneider Electric Blog<\/a>.<\/p>\n<p><a href=\"https:\/\/blog.schneider-electric.com\/oil-and-gas\/2019\/01\/08\/large-motor-starting-103-motor-starting-methods-how-to-choose-the-right-one\/\" target=\"bwo\" >http:\/\/blog.schneider-electric.com\/feed\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong>Credit to Author: Delcho Penkov| Date: Tue, 08 Jan 2019 12:36:11 +0000<\/strong><\/p>\n<p>This is the third post in our series on motor management covering various aspects of motor integration in an electrical network and the industrial process.
