This
advanced course involves hands-on exercises based on real world
projects, where you'll learn in-depth and practical knowledge of the
principles of proper and economical Arc Flash Hazard analysis through
the use of the SKM software. Hands-on lab exercises provided throughout
the course are designed to reinforce lecture content, enabling students
to gain practical experience designing and analyzing power systems with
the mindset of mitigating dangerous Arc Flash conditions. While this
course covers the Arc Flash evaluation module in detail and functions,
it also explores the real-world realities that apply to the every use
of the SKM software. Emphasis is placed on helping you develop skills
and knowledge in technical areas that can have practical value in your
projects!
This course is also structured to
expose intermediate and experienced users to robust and powerful
features that will enhance productivity and leave students saying “I
didn’t know I could do that!” Learn advanced SKM features quickly with
a fluid workflow and best practices!
Satisfy
OSHA requirements and steer clear of significant fines by protecting
employee safety. Avoid costly legal & medical expenses, downtime,
expensive equipment replacements, and insurance increases. Learn what
is needed to develop a successful Arc Flash program and comply with
sections of OSHA mandated NFPA 70E!
Objectives:
- Scope of work: A scope of work that will satisfy the requirements of the NFPA 70E-2012 standard.
- Scope of survey:
Detailed explanations and suggestions on how to perform a data
survey that balances both the requirement of the NFPA 70E standard and
the cost of the data collection process. How to proceed when
utility information is not available, when other component data is not
available or not accessible, or when library information is missing.
Determine appropriate tolerances when data is not precisely known.
- Modeling Components: How to model different component of the electrical distribution system (such as busducts) to obtain technical accuracy.
- Data Validating Techniques: Discuss input validating methodology for a complete system model to prevent errors in calculations due to bad data.
- Choosing Proper Options:
Before performing an Arc Flash study, many options should be
considered. Review all options that can cause a significant
difference in the Arc Flash results and provide suggestions on how to
select various options.
- DC Calculations: Understand and calculate incident energies for DC systems.
- Output of Results:
Results of the Arc Flash Hazard Analysis can be shown in
different document types. Explore all of types and provide
formatting suggestions to obtain useful and visually appealing
documents. Learn how to integrate Equipment Evaluation results in
the Arc Flash Hazard documents. Discuss the new NFPA 70E-2012
personal protection equipment requirements and how to include them in
labels and other output reports.
- Mitigation:
Explore the many practical mitigation techniques to reduce high
levels of incident energy. Suggestions on how to optimize
mitigation, protection, and coordination will be explored.
- Labeling: Discuss formating and printing arc flash labels. Methodology on how to affix labels to electric equipment.
Prerequisites:
- Basic computer skills
- SKM Power*Tools Standard 5-Day Training (101/102) OR working knowledge of SKM PTW Software
This class is not recommended for beginners. Instructor
will not delay the course answering basic questions regarding the use
of the PTW software not related to the Arc Flash study module.
- Students are urged to review:
- IEEE 1584 2002/2004a, Guide for Performing Arc Flash Hazard Analysis
- NFPA 70E-2004 Standard for Electrical Safety in the Workplace
Course Description:
This course covers the Arc Flash evaluation module in
detail and functions. The course involves hands-on lab exercises based
on real world projects, where you’ll learn in-depth and practical
knowledge of the principles of proper and economical Arc Flash Hazard
analysis through the use of the SKM software. Advanced SKM features
will be demonstrated to provide maximum productivity for experienced
users. Students will earn 2.0 CEUs for this 3-day course.
