Coltrane Systems has a highly experienced team of professionals specializing in Arc Flash Studies completing hundreds of studies.
Coltrane Systems inhouse IBEW Union Electricians are available to assist our engineers with field data collection.
Coltrane Systems will provide analysis of NEC compliance and provide recommendations.
Coltrane Systems implement “best practices” developed over years of experience resulting in successfully completing projects on-time, and under budget.
Our project management philosophy makes use of skills, knowledge, and tools to achieve the following goals:
BENEFITS OF ARC FLASH STUDY
Benefits of an Arc Flash Study include the following:

WHAT DOES THE CODE SAY ABOUT ARC FLASH STUDIES
OSHA 1910.132(d) states that the employer shall assess the workplace to determine hazards present, or are likely to be present, requiring the use of personal protective equipment (PPE). If such hazards are present, or likely to be present, the employer shall select, and have each impacted employee use the required PPE to protect employees from the hazards identified in the hazard assessment.
OSHA 1010.335(b)(1) states that safety signs, safety symbols, or accident prevention tags shall be used where necessary to warn employees about the electrical hazards which may endanger them.
OSHA recommends that employers consult standards such as NFPA 70E Handbook for Electrical Safety in the Workplace to identify safety measures that can be used to comply with OSHA standards for preventing or protecting against arc flash hazards.
NFPA 70E establishes procedures for arc flash hazard analysis.
National Electrical Code (NEC) requires electrical equipment that is likely to require examination, adjustment, servicing or maintenance while energized shall be labeled to warn qualified personnel of potential electric arc flash hazards.
HOW OFTEN IS AN ARC FLASH STUDY REQUIRED
The Arc Flash Study should be updated when changes occur in the electrical distribution system that could affect the results of the analysis. At a minimum, the Arc Flash Study should be reviewed for accuracy at intervals not exceeding 5 years.
WHAT DOES AN ARC FLASH STUDY TYPICALLY INCLUDE
An Arc Flash Study typically includes the following services:
ARC FLASH RISK ASSESSMENT
An Arc Flash Risk Assessment determines the Incident Energy, Arc Flash Boundary, and Personnel Protective Equipment (PPE) required for personnel to work on equipment live.
Once Assessment is complete, Arc Flash Labels are installed on electrical equipment.
An Overcurrent Protective Device Coordination Study analyzes the relationships between overcurrent protective device curves as depicted below. Recommendations are made to improve coordination, reduce nuisance tripping, improve protection of distribution system, and potentially reduce arc flash hazards.
SHORT CIRCUIT ANALYSIS
Short Circuit Analysis determines the maximum fault currents present throughout the Power Distribution System at various equipment locations and analyzes the adequacy of equipment Short Circuit Current Ratings (SCCR) to either withstand or clear the maximum fault currents that may be present. The National Electrical Code (NEC) requires that equipment be adequately rated for maximum fault currents.
If equipment is found to be inadequately rated, recommendations can be provided to increase the SCCR of existing equipment.
ADDITIONAL SERVICES OFFERED
Additional services offered include the following services:
AutoCAD One-Lines
Load Flow & Voltage Drop Analysis
Harmonic Analysis
Infrared Thermography Analysis
Safety Programs
AUTOCAD ONE-LINES
If your facility is old enough that AutoCAD drawings are not available, or perhaps have been lost, we can provide those.
Load Flow & Voltage Drop Analysis will provide calculated load flow current amperes and voltage drop throughout the Power Distribution System.
HARMONIC ANALYSIS
Harmonics typically are caused by non-linear loads connected to your Power Distribution System. A Harmonic Analysis will calculate the harmonic distortion levels, and based on our analysis corrective measures can be recommended. Benefits can include:
INFRARED THERMOGRAPHY ANALYSIS
Thermographic analysis is utilized to identify hot spots caused by defects in electrical connections and components. By identifying these hot spots, corrections can be made before components fail and cause damage to equipment, create potential safety hazards, or result in productivity losses. Benefits can include:
SAFETY PROGRAMS
Safety Programs offered include the following:
