Worse, inverters are even among the first to suffer from the occurrence of these phenomena.<\/span><\/p>\n<p class=\"Normal tm6\" style=\"text-align: justify;\"><span class=\"tm7\">These disturbances are often of external origin. They can come from :<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li class=\"ListParagraph tm8\">Transient overvoltages arriving through the agency&#8217;s power supply line following network disturbances (accidents affecting the lines), switching overvoltages (Ferranti effect), or triggering of protections in the vicinity (short-circuits)<\/li>\n<li class=\"ListParagraph tm8\">Temporary or permanent overvoltages caused by the cutting of the neutral conductor supplied by the energy distributor<\/li>\n<li class=\"ListParagraph tm8\">Temporary or permanent overvoltages caused by faults or uncorrected earth leaks in the neighbourhood<\/li>\n<li class=\"ListParagraph tm8\">Indirect lightning strike: Penetration of lightning current through the ground (step voltage).<\/li>\n<li class=\"ListParagraph tm8\">Rocky soil or unfavorable terrain (very high resistivity)<\/li>\n<li class=\"ListParagraph tm8\">Etc.<\/li>\n<\/ul>\n<p class=\"Normal tm6\" style=\"text-align: justify;\"><span class=\"tm7\">But disturbances of internal origin can also exist. They are often caused by:<\/span><\/p>\n<ul>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Degradation of the grounding system (high ohmic value of the grounding well, bad connections of the grounding conductors, etc.)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Untimely tripping of protections (in case of short-circuit on an outlet for example)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Ground leaks on some feeders or insulation faults on equipment, not detected (air conditioners, lighting, etc.)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Poor distribution of the protective conductor (equipotentiality)<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/4&#8243;][vc_cta h2=&#8221;Download the brochure&#8221; txt_align=&#8221;center&#8221; add_button=&#8221;bottom&#8221; btn_title=&#8221;Download&#8221; btn_align=&#8221;center&#8221; add_icon=&#8221;top&#8221; i_icon_fontawesome=&#8221;fas fa-cloud-download-alt&#8221; btn_link=&#8221;url:http%3A%2F%2Felexpert.ma%2Fwp-content%2Fuploads%2F2021%2F07%2FP28.pdf|title:Solutions|target:%20_blank|&#8221;][\/vc_cta][\/vc_column][\/vc_row][vc_row cspt-text-color=&#8221;white&#8221; cspt-bg-color=&#8221;globalcolor&#8221; full_width=&#8221;stretch_row&#8221; css=&#8221;.vc_custom_1631449639763{padding-top: 50px !important;background-color: #ff9314 !important;}&#8221;][vc_column][vc_column_text]<\/p>\n<p class=\"Normal tm6\" style=\"text-align: justify;\"><span class=\"tm7\">ELEXPERT offers a unique solution on the market, designed to improve the continuity of service in bank branches, preserve the equipment installed there and optimize their lifespan.<\/span><\/p>\n<p class=\"Normal tm6\" style=\"text-align: justify;\"><span class=\"tm7\">The solution includes several features offering:<\/span><\/p>\n<ul>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Protection against rapid variations in the voltage of the electrical network, allowing to compensate for voltage dips, undervoltage and a large part of micro outages. This static voltage stabilizer-regulator function also protects the equipment against permanent or temporary overvoltages arriving through the external line, in addition to ensuring a very stable voltage for the equipment (+\/- 3%), thus improving their life span.<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Protection against overvoltages due to coupling phenomena and the circulation of fault currents from the external network (galvanic isolation transformer)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Protection against overvoltage due to cutting of the neutral conductor (local neutral tap)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Protection against transient switching surges and lightning strikes (internal surge protectors)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Protection against very high frequency interference voltages (LC filter between neutral and ground)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">A protection against overvoltages due to electrostatic discharges (electrostatic screen)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Protection of persons and equipment against indirect contact by intelligent, ultra-immune differential relay with earth leakage current display<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Possibility to adjust the output voltage level between 210 and 240V +\/- 3% (voltage regulator function)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Automatic reset of protections (optional). This function can be crucial in the case of pharmaceutical laboratories or bank branches that need to operate strategic machines during the night and weekends (automats, servers, ATMs, etc.). 7 out of 10 trips are often due to temporary phenomena (first rains, atmospheric disturbances, etc.) and do not require repair. It is therefore sufficient to reset the differential protections in these cases.<\/li>\n<\/ul>\n<p>[\/vc_column_text][vc_single_image image=&#8221;13522&#8243; img_size=&#8221;large&#8221;
