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
