Arc Flash

Arc Flash Hazard Analysis & Mitigation

  • Determine the risk of personnel injury as a result of exposure to incident energy (IE) released during an arc-flash event
  • Provide recommendations for appropriate arc-flash hazard protection
  • Inform the personnel about the existing arc electrical safety.
  • Comply with OSHA, NEC, and NFPA 70E requirements

Short Circuit Studies

  • Calculate the fault current at various locations in the plant.
  • Identify whether the system and the equipments could withstand the available fault current.
  • Specify the ratings of the equipments for future expansions.
  • Improve the reliability of the system.

Over-current Protective Device Coordination

  • Prevent injury to personnel
  • Minimize damage to system components
  • Limit the extent and duration of service interruption whenever equipment failure, human error, or adverse natural events occur on any portion of the electrical power system.

Dynamic Motor Starting Analysis

  • Determines the expected voltage dip and acceleration time for a motor  
  • Examines the impacts of motor starting on an electric power system.

Equipment Assessments

  • Identify the under-rated equipments that cannot safely interrupt the fault current.
  • Recommend replacements to the "failed" equipments.
  • Avoid extensive equipment failure, system outages, and personnel injury by underrated equipments in the event of a fault.

Development of Single Line Drawings For As-Builts

  • Point-to-point sketch of actual connected plant loads, beginning at the PCC, and collection of all pertinent component data.
  • Based on the collected information, single-line diagrams are re-created to show the current configuration and modes of operation of the system.
  • SKM PTW or ETAP EE software is used for creating single-line diagrams and modeling the components.

Load Flow Studies

  • Component or Circuit Loading
  • Bus Voltage Profiles
  • Real and Reactive Power Flow
  • Power System Losses
  • Proper Transformer Tap Settings

Power Factor Correction Studies

  • Release of Power System Capacity (kVA)
  • Improved Bus Voltage Profiles
  • Reduced Power System Losses
