It offers up to six three-phase restraint inputs, three independent restricted ground fault (REF) protection elements, and two three-phase voltage inputs. The SEL-487E limits transformer damage by responding to internal fault conditions in less than 1.5 cycles. The relay also helps prevent catastrophic transformer failure by detecting turn-to-turn faults involving as little as 2% of the total winding. You can reduce commissioning time and eliminate costly errors with included software that recommends matrix compensation settings. Thermal and through-fault monitoring allows you to track transformer wear and schedule maintenance as needed. Circuit breaker wear monitoring saves time and money by reducing the need for costly and inefficient maintenance. The SEL-487E includes two differential elements and complete feeder and distance protection, making it possible to fully protect a distribution substation with a single device. Use the SEL-487E-4, with its 6 voltage and 18 current terminals, as the substation's phasor measuring unit.<\/p><p style=\"font-weight: 400;\">Transform the way you modernize your substation with optional Time Domain Link (TiDL) technology or Sampled Value (SV)-based technology using IEC 61850-9-2.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-79a8683 elementor-mobile-align-center elementor-widget elementor-widget-button\" data-id=\"79a8683\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/gridenergy.ma\/en\/contact\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">REQUEST A QUOTE<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-9debea2 e-con-full e-flex e-con e-child\" data-id=\"9debea2\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f528a17 elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"f528a17\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"900\" height=\"655\" src=\"https:\/\/gridenergy.ma\/wp-content\/uploads\/2025\/04\/487E_Front.png-1024x745.jpeg\" class=\"attachment-large size-large wp-image-14725\" alt=\"\" srcset=\"https:\/\/gridenergy.ma\/wp-content\/uploads\/2025\/04\/487E_Front.png-1024x745.jpeg 1024w, https:\/\/gridenergy.ma\/wp-content\/uploads\/2025\/04\/487E_Front.png-300x218.jpeg 300w, https:\/\/gridenergy.ma\/wp-content\/uploads\/2025\/04\/487E_Front.png-768x559.jpeg 768w, https:\/\/gridenergy.ma\/wp-content\/uploads\/2025\/04\/487E_Front.png.jpeg 1440w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>SEL-487E Accueil SEL SEL-487E Relais de protection de transformateur.
