course has been redeveloped to include additional materials including
photovoltaic systems and new DC Arc Flash methods based on Dan Doan's
IEEE paper and NFPA 70E
2018. This course is geared towards electrical power engineers
responsible for the design and analysis of DC systems
as well as managers responsible for reviewing and approving
studies. Join us and learn from the expert that developed the DC
Arc Flash equations that is used in the SKM software! Feel free to bring your own questions!
Discussions include an overview on commonly used DC
equipment and the application of the Power*Tools program to analyze
example DC electrical distribution systems. Battery sizing, load-flow,
short-circuit, protection, and DC arc flash studies will be reviewed
and then performed using the software.
- Review of DC equipment (Batteries, PV, Rectifiers,
Inverters, and Loads)
- DC Short Circuit calculations
- DC Protection overview
- Review of DC Arc Flash methods (Method to use based on application & limitations)
- Provide practical DC system examples from typical industrial and commercial power systems with explanations of why the
study results are presented.
- Discuss issues, examine study results and potential problem
- Discuss considerations when selecting equipment, along with
explaining equipment datasheets.
- Provide relevant information needed to successfully
complete a DC Systems study.
This course will be instructed by experts Daniel Doan and Ruperto Sanchez with
a combined 55 years of power systems experience.
Daniel R. Doan was the Principal Consultant for DuPont
in Wilmington, Delaware for 35 years.
Dan received his BSEE and MSEE degrees from the Massachusetts Institute
of Technology (MIT). He has co-authored IEEE
papers at IAS/PCIC and Pulp&Paper on subjects ranging from electrical
safety to electrical system reliability and operations. He has co-authored PCIC Tutorials on
Electrical System Reliability and Arc Flash Hazard Analysis, and has
participated in many IAS Electrical Safety Workshops as author and
is an IEEE Fellow, Secretary of the IEEE IAS Electrical Safety
Committee, a member of the IEEE 1584 ‘Guide for Performing Arc-Flash
Hazard Calculations’ Working Group, and is a registered Professional
Engineer in Pennsylvania.
Ruperto G. Sanchez is a Senior Engineer for SKM Systems
Analysis, Inc. where he provides technical support for all the SKM Power*Tools products.
He has instructed thousands of engineers on the SKM Power*Tools software worldwide
and assists Project Engineers with short circuit, load flow, motor starting,
arc flash hazard analysis and other power system studies. Ruperto received his BSEE with emphasis in
Power Systems from California State Polytechnic University, Pomona. Ruperto
has 20 years of experience in the
application of engineering computer software and is a member of the
