Arc Flash Solutions

Per NFPA 70E, the electrical safety program shall be audited at intervals not to exceed 3 years. The Arc Flash assessment has become an important factor in the electrical safety program. Per NFPA 70-2018 the incident energy analysis shall be updated when changes occur in the electrical system that could affect the result of the analysis. 

The incident analysis shall be reviewed for accuracy at an interval not to exceed 5 year. Mangan PDG understands that each client has a unique specification and provides a customized approach to each Arc Flash project for Arc Flash Safety Solutions.

NFPA Arc Flash Analysis Assessments Steps

Facilities

  • All Hot-Work Facilities
  • Industrial Processing Plants
  • Power Generation Stations
  • Municipal Utility Facilities
  • 911 Call Centers
  • Reviewing existing Single Line Diagrams and other available existing documentation
  • Team up with the client to collect system and installation data
  • Provide execution plans for shut down and access to electrical equipment
  • Coordinating with operations and end-users engineer to determine the system modes of operation,
  • Modeling the system per available documentation and collected data using ETAP, SKM or EasyPower software.
  • Running the Arc Flash studies per IEEE 1584-2018 or ArcFault Method.
  • Providing arc flash mitigation recommendations where incident energy is above the acceptable levels. Some of the Arc Flash Mitigation methods are:

    • Use of a breaker or relay with a maintenance mode to enabled or lower instantaneous settings
    • Zone Selective Interlocking
    • High Impedance or Low Impedance Differential bus protection
    • Relays with Fiber or optical sensor input
    • Use of Arc Resistant equipment
    • Arc Current Limiter
    • Remote operation of circuit breakers
    • Isolation of main breakers from commonly accessed equipment
  • Assist with prioritization and risk ranking of associated high incident energy sources.
  • Execute the mitigation recommendations in future projects

Arc Flash Mitigation Services

Here at Mangan PDG, we understand that each client has specific requirements. That is why we provide flexible and innovative designs that are tailored to exactly what you need for Arc Flash Safety Solutions.

The Arc Flash assessment has become an important factor in the electrical safety program.

Because of this, we make sure that it is audited at least every three years, as per the NFPA 70E regulation. In addition to that, the incident energy analysis shall be updated when any changes occur in the electrical system that could affect the result of the analysis, and the incident analysis will be reviewed for accuracy at least once every five years, so you know that everything is above board and up to date.
