The Surge Protection Measures (SPM) 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.

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.

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.

SCOPE OF WORK

Within the scope of Surge Protection Measures, A3A Engenharia de Sistemas can operate in the following areas:

Planning and Sizing

  • Assessment of transient and surge exposure
  • Definition of protection zones and coordination levels
  • Sizing of SPDs for main, secondary, and terminal boards
  • Compatibility with grounding and equipotentialization systems
  • Preparation of technical design and documentation

Implementation and Integration

  • Installation of surge protective devices in strategic points
  • Interconnection with electrical boards and critical circuits
  • Integration with UPS systems, automation, and sensitive loads
  • Technical supervision of assembly and energization

Testing and Validation

  • Verification of installation and device coordination
  • Inspection of grounding and protection continuity
  • Validation of technical documentation and executive design
  • Consolidation of records and acceptance reports

Maintenance and Review

  • Periodic inspection of protective devices
  • Replacement after events or end of life
  • Review according to expansion of circuits and loads
  • Update of technical records and mitigation criteria

APPLICATIONS AND ENVIRONMENTS

The solution applies to:

  • Corporate buildings
  • Industrial plants
  • Critical infrastructures
  • Data centers
  • Installations with sensitive electronic loads
  • Sites exposed to electrical transients and switching events

The architecture is sized to ensure mitigation of overvoltages, preservation of electrical and electronic assets, and greater operational predictability of the protected installation.
