Instructors Biography Jim Phillips, P.E.Jim is a licensed Professional Engineer in many states and a member of the Institute of Electrical and Electronics Engineers IEEE where he is a member of IEEE P1584 - IEEE Guide for Performing Arc Flash Calculations. He wrote the guide, How to Perform an Arc Flash Study in 12 Steps published by NFPAs NEC Digest and available at www.brainfiller.com He is also CoChairman of the Task Group IEEE 1584.1 which is a guide for specifying arc flash studies. He is also founder of www.ArcFlashForum.com Jim wrote the book on arc flash and is the author of How to Perform and Arc Flash Study released by NFPAs publisher later in 2009. Jim earned a BSEE Degree from The Ohio State University. After college, his first real world job was with Square D Company's Power System Analysis Group in Lexington, Kentucky where he was responsible for performing power system studies, developing power system analysis software and teaching at their training programs (where his teaching bug all began!) He later moved on to work for Ohio Edison Company in Akron, Ohio in the Transmission Planning Group and later in the System Protection Group where he was in charge of the staff responsible for various power system studies. He also taught classes at Stark State College on the National Electrical Code and Transmission and Distribution Systems. Jim was also the founder of a training company called T2G Technical Training Group which started out small in 1987 but over the years grew to include many instructors. As the other instructors eventually moved on, the teaching staff eventually became just Jim. Although the T2G name still exists, the company is really just an extension of Jim's desire to help all who want to learn as much as they can about electric power distribution. Jim also formed Phillips Engineers + Consultants, Inc. which is an engineering firm specializing in the design and analysis of electrical power systems. He has provided electrical design for everything from small commercial buildings to large scale cogeneration power plants. The countless power system analysis projects that he has undertaken on everything from waste water treatment plants to aircraft carriers have given him a unique perspective on power system analysis.

26 Other Classes By Jim Phillips, P.E.DESIGN OF ELECTRIC POWER SYSTEMS - I Learn the basics of design including load calculations, voltage drop, voltage selection, conductor sizing, overcurrent protection, lighting design, grounding and more. DESIGN OF ELECTRIC POWER SYSTEMS -II Transformers, motor circuits, hazardous location design, power factor correction, harmonics, oversized neutrals, emergency power systems are all part of this design class. ELECTRIC POWER CALCULATIONS PER UNIT Very few universities teach the per unit system anymore but it is still a fundamental concept for electric power systems. This class teaches you the basics of electric power calculations including the per unit system for system modeling.

GENERATOR AND UPS APPLICATIONS - I With electric utility deregulation and large scale blackouts emergency and standby power systems are more important than ever. This class covers the requirements of sizing, operation, protection and planning a generator installation. Included is how to analyze the effect of harmonic producing loads and motor starting on the generator operation. GENERATOR AND UPS APPLICATIONS - II Power systems are facing a decrease in reliability yet mission critical systems must have 100% reliability. This class will show you how to properly size a UPS system, transfer switches selection, UPS heat loss, reliability, compatibility issues and more. GROUNDING AND POWER QUALITY Grounding is one of the more commonly mis-understood concepts of a power system. Poor or incorrect grounding can lead to safety and power quality problems. Learn the correct methods for grounding according to the NEC and IEEE. See how to locate and correct power quality problems including ground loops. HOW TO PERFORM AN ARC FLASH STUDY - I This class is based on OSHA and NFPA 70E and is designed to train students to understand electrical safety including shock and arc flash hazards as well as providing appropriate hazard assessment. Learn flash boundary calculations based on NFPA 70E, limited, restricted and prohibited approach boundaries, correct personnel protective equipment and many other topics. HOW TO PERFORM AN ARC FLASH STUDY - Il The class is based on IEEE 1584 and shows how to perform the detailed arc flash study including data collection and IEEE calculations. Jim discusses the effect of device settings and short circuit current magnitudes on arc flash as well as holes in the standards.

HOW TO STREAMLINE AND AUTOMATE ELECTRIC POWER DESIGN - I Learn how to develop design tables to more easily and quickly design electrical power systems. Day 1 covers conductor / protection tables and motor circuit sizing tables. This course is based on the NEC and power system design concepts. HOW TO STREAMLINE AND AUTOMATE ELECTRIC POWER DESIGN - II Day 2 covers developing transformer tables, grounding, interfacing with the utility. Jim has developed design worksheets to aid in quick calculations and fewer errors. This class also has a demonstration of commercially available software to automate the design process.

Other Classes By Jim Phillips, P.E.

POWER FACTOR AND HARMONIC ANALYSIS How do you manage harmonics? Learn how to analyze harmonics, perform resonance calculations, understand IEEE 519, perform THD calculations and design harmonic filters. In addition, learn what to do about neutral harmonics which often require oversized neutrals and K rated transformers. Understand the interaction between harmonics and power factor correction capacitors. POWER SYSTEM ENGINEERING COURSE 4 DAYS This course has become the industry standard that defines the Crash Course in electrical power systems. People from all over the world have attended this course at Jims public sessions. The class is a combination of his five most popular courses rolled into a 4 day program. The five courses include: Design of Electric Power Systems I and II, Short Circuit Analysis, Protective Device Coordination Analysis and Harmonic Analysis. PROTECTIVE DEVICE COORDINATION ANALYSIS This course is designed to show you how to use time current curves and perform coordination studies with breakers, relays and fuses. The program provides an explanation of how to maximize reliability by developing a properly coordinated power distribution system. PROTECTIVE RELAYING - I It has been said that protective relay coordination is more of an art than science. This class introduces you to overcurrent relays, relay coordination, current transformer burden and saturation. Many relay examples are included. PROTECTIVE RELAYING - II A continuation of the basic class, this class shows how other relays operate and are set such as differential, synch check and reverse power relays.
