A problem at this level can result in production lines being shut down and services stopped for long periods of time, ranging from several hours to several days in some cases.<\/span><\/p>\n<p class=\"Normal tm6\" style=\"text-align: justify;\"><span class=\"tm7\">In addition, access by outsiders (management personnel, maintenance companies, etc.).<\/span><\/p>\n<p class=\"Normal tm6\" style=\"text-align: justify;\"><span class=\"tm7\">The main points to control in a MV\/LV substation are :<\/span><\/p>\n<ul>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Transformer temperature: It gives a direct indication of the load and operating conditions of the transformer. Temperature is a stressor for resin insulators and a chemical and physical alteration factor for mineral insulating oil for immersed transformers. When it exceeds a certain threshold, it can strongly accelerate the aging of these insulators.<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Other alarms from the transformer&#8217;s DGPT2 device<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Temperature distribution : it gives a precise idea of the good oil circulation in the immersed transformers, which allows to detect and anticipate many internal problems, such as the need for purging, &#8230;<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Ambient temperature in the station or cabin<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Humidity level and dew point calculation, which have a considerable impact on the insulation of medium voltage cells and transformer insulators.<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">The load level of the transformer. This depends on the intensity of the current flowing through it, but also on the iron losses caused by the circulation of harmonic currents. Measuring and monitoring the transformer&#8217;s k-factor allows the actual load level of the transformer to be calculated and the life of the transformer to be maintained.<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">The main electrical parameters of the installation: currents, voltages, powers, power factor, frequency, energies, harmonics, etc.<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">The load curve: monitoring of active and reactive power calls by time slot,<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Electrical disturbances, power outages and voltage quality events: this is the most suitable point of the installation to measure and detect voltage quality events, according to the EN50160 standard, because it represents the point of coupling to the public grid (PCC) but also because it is at this level that all the harmonic currents created by the loads of the plant or the building go up.<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">The total earth leakage current in the case of TT and TNS systems, or the overall insulation level in the case of an IT system<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">The operating status (On\/ Off\/ Fault) of the protection and control equipment: status of the cells, the general circuit breaker, etc.<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">The operating status of the compensation battery when it is present (reactive power, number of steps engaged, alarms generated, rate of capacity loss, etc.)<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Alarms coming from fire control units or access control units when they exist<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Monitoring of access to the workstation: time stamping of accesses, number of accesses per period, etc.<\/li>\n<\/ul>\n<p>[\/vc_column_text][vc_column_text]<\/p>\n<p class=\"Normal tm6\" style=\"text-align: justify;\"><span class=\"tm7\">In addition to the monitoring and recording of these parameters, the sending of alarms in real time ensures effective and rapid interventions, when necessary, allowing the containment of problems as soon as they occur, before they have time to cause irreparable damage such as :<\/span><\/p>\n<ul>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Overheating,<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Flooding (detection of water or oil at ground level),<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Insulation or current leakage problems<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Protection triggers<\/li>\n<li class=\"ListParagraph tm8\" style=\"text-align: justify;\">Access by a stranger,<\/li>\n<li
