Protection Measures (SPM)"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">The <strong>Surge Protection Measures (SPM)<\/strong> solution includes the design and implementation of a structured system to mitigate overvoltages caused by lightning, switching operations, and disturbances in the electrical network, protecting electrical and electronic assets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The architecture is structured to ensure coordinated protection levels, compatibility between protective devices and the installation, and proper integration with grounding, equipotentialization, and electrical infrastructure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A3A Engenharia de Sistemas develops each solution based on analysis of transient exposure, criticality of protected loads, system topology, and technical standards, ensuring predictability and protection effectiveness.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SCOPE OF WORK<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Within the scope of Surge Protection Measures, A3A Engenharia de Sistemas can operate in the following areas:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Planning and Sizing<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Assessment of transient and surge exposure<\/li>\n\n\n<li>Definition of protection zones and coordination levels<\/li>\n\n\n<li>Sizing of SPDs for main, secondary, and terminal boards<\/li>\n\n\n<li>Compatibility with grounding and equipotentialization systems<\/li>\n\n\n<li>Preparation of technical design and documentation<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Implementation and Integration<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Installation of surge protective devices in strategic points<\/li>\n\n\n<li>Interconnection with electrical boards and critical circuits<\/li>\n\n\n<li>Integration with UPS systems, automation, and sensitive loads<\/li>\n\n\n<li>Technical supervision of assembly and energization<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Testing and Validation<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Verification of installation and device coordination<\/li>\n\n\n<li>Inspection of grounding and protection continuity<\/li>\n\n\n<li>Validation of technical documentation and executive design<\/li>\n\n\n<li>Consolidation of records and acceptance reports<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Maintenance and Review<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Periodic inspection of protective devices<\/li>\n\n\n<li>Replacement after events or end of life<\/li>\n\n\n<li>Review according to expansion of circuits and loads<\/li>\n\n\n<li>Update of technical records and mitigation criteria<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">APPLICATIONS AND ENVIRONMENTS<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The solution applies to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Corporate buildings<\/li>\n\n\n<li>Industrial plants<\/li>\n\n\n<li>Critical infrastructures<\/li>\n\n\n<li>Data centers<\/li>\n\n\n<li>Installations with sensitive electronic loads<\/li>\n\n\n<li>Sites exposed to electrical transients and switching events<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The architecture is sized to ensure mitigation of overvoltages, preservation of electrical and electronic assets, and greater operational predictability of the protected installation.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"<p>Structured surge mitigation system for protection of electrical and electronic
