Arc Flash Study and Mitigation Services

Arc Flash Study and Mitigation Services

OUR SOLUTIONS

Because of the explosive nature of equipment failures, serious burn injuries
in the electrical industry are of great concern. Detailed investigation into
arc flash incidents has led the National Fire Protection Association (NFPA)
to adopt arc flash guidelines (NFPA-70E) for work on or near energized
electrical equipment. Arc flash studies help ensure employee safety against
dangers associated with the release of energy caused by an electrical arc,
ensure compliance with industry safety standards, and provide required
device labeling to communicate proper levels of Personal Protective
Equipment (PPE) and safe approach/working distances.

EN Consulting, a sector of ENTRUST Solutions Group, has extensive experience
in arc flash analysis within industrial, utility generation, and commercial
environments, including refineries, heavy and light oil terminals, utility
generation facilities, recreational buildings, convenient stores, large
production facilities, and chemical production facilities. Our highly
qualified and licensed professional engineers provide technically compliant
arc flash reports, arc flash equipment labels, electrical hazard training,
and arc flash mitigation services to help eliminate hazards.

IMPORTANT CONSIDERATIONS

  • Has an arc flash study been performed at your facility in the last 5
    years?
  • Does your electrical equipment have arc flash labels that comply with the
    latest NFPA 70E requirements?
  • Have you made changes to your electrical distribution system since the
    last arc flash study was performed?
  • Have your electricians received safety training to identify electrica

EN CONSULTING ARC FLASH STUDY SERVICES

  • Conduct site visits to collect data and build a model of your facility’s
    power system
  • Obtain short circuit, transformer, and protective device information
  • Create a system model using the latest version of ETAP, SKM, or EasyPower
    software
  • Perform short circuit and equipment duty evaluations to identify
    underrated electrical equipment
  • Perform a protective device coordination study to ensure protective
    devices will selectively open during a fault condition
  • Perform an arc flash hazard study
  • Create a report on the findings of the power system studies, provide
    recommendations, and review with management
  • Generate arc flash labels along with a label key

In addition, EN Consulting can perform the following optional services:

  • Install arc flash labels
  • Conduct Electrical Hazard Training which meets requirements of
    NFPA-70E-2018 for training qualified employees
  • Perform a preventive maintenance evaluation in compliance with NFPA
    70E-2018 Section 205.3 and compile maintenance records necessary to meet
    this requirement

MITIGATION SERVICES

As part of EN Consulting’s arc flash study, recommendations will be made to
mitigate arc flash hazards. Usually these are areas where the incident
energy exceeds 40 cal./cm2. Typical recommendations may include adjustment
of protective device settings, administrative controls, or the purchase of
remote breaker operating mechanisms. EN Consulting design professionals have
considerable experience implementing engineered solutions to mitigate arc
flash hazards, some of which include:

  • Replacement of molded case circuit breakers with adjustable trip units
  • Retrofitting power circuit breakers with solid state trip units and
    maintenance mode (fast trip) devices
  • Protective relaying upgrades (zone-selective interlocking, differential
    relaying, energyreducing maintenance switching)
  • Replacement of existing switchgear with arc resistant switchgear
  • Installation of Arc Flash Light Detection Relay systems
  • Installation of High Resistance Grounding systems
