In the preventive maintenance strategy, the breaker is subject to regular timing tests to detect trends in the degradation and aging of the equipment, so that corrective action may be applied before the problems become a danger to the network or to the personnel.<\/p>\n<p><a href=\"http:\/\/: https:\/\/www.zensol.com\/en\/circuit-breaker-testing\/troubleshooting-examples\/ \u200e\" target=\"_blank\" rel=\"noopener\">Read more &gt;&gt;<\/a><\/p>\n<\/div><\/section><\/div>\n<div class='flex_column av-av_one_fourth-f78fb3c186c5ceb3cf0bf54353219056 av_one_fourth flex_column_div '     ><section  class='av_textblock_section av-av_textblock-0366cc7376be6c9e82a3e9cc8987b64f'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><article  class='iconbox iconbox_left av-av_icon_box-24eb8b891035ecbad5579f68b012d931'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class=\"iconbox_content\"><header class=\"entry-content-header\"><div class=\"iconbox_icon heading-color\" aria-hidden='true' data-av_icon='\ue871' data-av_iconfont='entypo-fontello'><\/div><h3 class='iconbox_content_title '  itemprop=\"headline\" >Related products: <a title=\"HV Circuit Breaker Vibration Analyzer \u2013 CBV-32\" href=\"https:\/\/www.zensol.com\/en\/product\/circuit-breaker-analyzer-24-contacts\/\">CBA-32<\/a>P, <a href=\"https:\/\/www.zensol.com\/en\/product\/hv-circuit-breaker-vibration-analyzer-cbv-19\/\">CBV <\/a>  <\/h3><\/header><div class='iconbox_content_container '  itemprop=\"text\" ><\/div><\/div><footer class=\"entry-footer\"><\/footer><\/article>\n<\/div><\/section><\/div>\n<div  class='hr av-av_hr-dcd2069817a0e3d34ae04cad8f3443c7 hr-default'><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<div class='flex_column av-av_three_fourth-2a9015ff38129c418a3f2eafba3e9512 av_three_fourth first flex_column_div '     ><section  class='av_textblock_section av-av_textblock-0366cc7376be6c9e82a3e9cc8987b64f'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h3>Breaker timing<\/h3>\n<h2><strong>1.1\u00a0 THE ELECTRIC NETWORK<\/strong><\/h2>\n<p>Electricity is a natural phenomenon.

><h3>An expert system for acoustic diagnosis of power circuit breakers and on-load tap changers<\/h3>\n<p>Article from Expert Systems with Applications\u00a0&#8211;\u00a0olume 42, Issue 24, 30 December 2015, Pages 9426\u20139433<\/p>\n<h2 class=\"greenbold\">Abstract<\/h2>\n<p><i>Most of the faults on power Circuit Breakers (CBs) and On-Load Tap Changers (OLTCs) on high voltage transformers are of mechanical origin. Mechanical malfunction, mechanical wear and other types of abnormal behaviors can be detected as changes in the acoustic signatures. In this paper, an Expert System (ES) with the addition of a signal processor module and factual database module to the conventional ES has been proposed for the diagnosis of CBs and OLTCs. The feature extraction of the acoustic signatures has been done by decomposing them into voiced and silent portions in time domain and through FFT spectrum analysis in frequency domain. The OLTC&#8217;s motor current has been decomposed into inrush, steady-state and extended currents to locate the cause of different anomalies in the OLTCs and acoustic-current pair has been used for the synchronization testing. Each extracted feature of the testing signal has been compared to the similar feature of a reference signal to not only identify the health of the testing device but also to locate the cause of each anomaly. Several test signals have been compared against the reference signature and the proposed expert system has proved to be a suitable, effective and reliable system for the acoustic diagnosis of OLTCs and CBs.<\/i><\/p>\n<p><a title=\"Maintenance of MV and HV Power Circuit Breakers\" href=\"https:\/\/www.zensol.com\/pdf\/An-expert-system-for-acoustic-diagnosis-of-power-circuit-breakers-and-on-load-tap-changers.pdf\">Read more &gt;&gt;<\/a><\/p>\n<\/div><\/section><\/div>\n<div class='flex_column av-av_one_fourth-f78fb3c186c5ceb3cf0bf54353219056 av_one_fourth flex_column_div '     ><section  class='av_textblock_section av-av_textblock-0366cc7376be6c9e82a3e9cc8987b64f'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><article  class='iconbox iconbox_left av-av_icon_box-39804582cc024588cfd4e364e9b1efbe'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class=\"iconbox_content\"><header class=\"entry-content-header\"><div class=\"iconbox_icon heading-color\" aria-hidden='true' data-av_icon='\ue871' data-av_iconfont='entypo-fontello'><\/div><h3 class='iconbox_content_title '  itemprop=\"headline\" >Related products: <a title=\"HV Circuit Breaker Vibration Analyzer \u2013 CBV-32\" href=\"https:\/\/www.zensol.com\/en\/product\/hv-circuit-breaker-vibration-analyzer-cbv-32\/\">CBV-32<\/a>   <\/h3><\/header><div class='iconbox_content_container '  itemprop=\"text\" ><\/div><\/div><footer class=\"entry-footer\"><\/footer><\/article>\n<\/div><\/section><\/div>\n<div  class='hr av-av_hr-dcd2069817a0e3d34ae04cad8f3443c7 hr-default'><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<div class='flex_column av-av_three_fourth-2a9015ff38129c418a3f2eafba3e9512 av_three_fourth first flex_column_div '     ><section  class='av_textblock_section av-av_textblock-0366cc7376be6c9e82a3e9cc8987b64f'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h3>Maintenance of MV and HV Power Circuit Breakers<\/h3>\n<p>Article from <span class=\"rubybold\">Electric Energy T&amp;D<\/span>, Magazine &#8211;
