Southwest Energy Systems conducts engineering studies to ensure electrical safety, reliability, and compliance with industry standards. By performing an arc-flash hazard analysis, we can determine incident energy levels and the appropriate safety measures necessary so personnel can work safely around the energized equipment. We can also perform a short-circuit study to determine the available fault current in an electrical system, and a coordination study to determine the appropriate equipment settings to prevent unnecessary damage and outages in the event of a fault. In addition to being mandated by law, these studies are considered an engineering “best practice” and provide safety and peace of mind for your personnel. In the process, you are also protecting your electrical equipment and valuable infrastructure.

Our engineering studies comply with industry standards, including OSHA and NFPA 70E. Some of our engineering services include:

  • Arc Flash Hazard Analysis
  • Short Circuit Studies
  • Coordination Studies
  • Load Flow Studies
  • Harmonics/Grounding
  • Protective Relay Logic and Program Development
  • Power Quality Studies
  • Capacity Analysis
  • Motor Starting
  • Transient Voltage Analysis
  • Ground Fault Studies

Commissioning of electrical systems, a process in which a system undergoes extensive quality assurance testing and examination to ensure the system will operate as intended in a safe and efficient manner, is a well-accepted and critical step in the building process. Commissioning can occur at any time in the lifecycle of a building or facility. Retro-commissioning is commonly performed on existing buildings to maximize efficiency and safety. Southwest Energy Systems Technicians and Engineers perform, manage and document commissioning projects for electrical systems from 120 Volts to 500,000 Volts.
