It is often possible to solve interruption or micro outage problems with much simpler solutions.<\/p>\n<p>The detailed analysis of the phenomenon, its occurrence, its frequency, its depth, its duration, etc. allows to determine the most appropriate solution for each case. In addition, it is very important to take into account the installation environment of the solution, in the choice and sizing of the latter (humidity, temperature, altitude, atmospheric pollution, nature of the loads to be protected, voltage variation range, etc.).<\/p>\n<p>Among the solutions we use, we can mention:<\/p>\n<ul>\n<li>on-line double conversion inverters<\/li>\n<li>industrial off-line inverters<\/li>\n<li>dynamic voltage regulators (DVR)<\/li>\n<li>voltage stabilizers<\/li>\n<li>voltage regulators<\/li>\n<li>static compensation batteries<\/li>\n<li>electronic VAR generators<\/li>\n<li>Etc.<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_raw_html]PHZpZGVvIGF1dG9wbGF5PSIiIGxvb3A9IiIgbXV0ZWQ9IiIgY29udHJvbHM9IiIgd2lkdGg9IjEwMCUiPgoKICAgIDxzb3VyY2Ugc3JjPSJodHRwczovL2VsZXhwZXJ0Lm1hL3dwLWNvbnRlbnQvdmlkZW9zL01pY3JvY291cHVyZXMud2VibSIgdHlwZT0idmlkZW8vd2VibSI+CiAgU29ycnksIHlvdXIgYnJvd3NlciBkb2Vzbid0IHN1cHBvcnQgZW1iZWRkZWQgdmlkZW9zLgo8L3NvdXJjZT48L3ZpZGVvPg==[\/vc_raw_html][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row&#8221; css=&#8221;.vc_custom_1591394175233{padding-top: 50px !important;padding-bottom: 50px !important;}&#8221;][vc_column][vc_column_text]<\/p>\n<p class=\"Normal tm5\" style=\"text-align: justify;\"><span class=\"tm6\">90% of operators think that micro outages come from the external network, whereas experience has shown that the opposite is true in 80% of cases.<\/span><\/p>\n<p class=\"Normal tm5\" style=\"text-align: justify;\"><span class=\"tm6\">That&#8217;s why, from the start, our experts start by determining whether the problem originates from the site or from the public network.
