The following people make up Lewellyn Technology’s Arc Flash Assessment Team. These Arc Flash Engineers are responsible for Arc Flash Hazard Analysis, Arc Flash Consulting, and Arc Flash Training. At Lewellyn Technology we strive to be a national leader in workplace safety and performance.
Chris Guffey, PE
Title: Engineering Manager
School: Rose-Hulman Institute of Technology
Degree: B.S. Electrical Engineering
Duties: Engineering Manager responsible for supervising engineering work associated with Arc Flash Analysis including, but not limited to, data collection, construction of the electrical model in the SKM software, short circuit study, coordination study, and final recommendations for reducing arc flash levels as found in the arc flash study. Over 8 years of experience utilizing the SKM software as well as 5 years of arc flash experience.
Six years of industrial power and control design in the consulting industry. Including power distribution network design, equipment layout and sizing, conductor routing, control schematics, drawing preparation, and specifications for a complete bid package.
Industries: Hospital campuses, metal recycling facilities, schools, retail outlets, power generation facilities, industrial manufacturing facilities including retail, steel mills, paper mills, water and waste water facilities, and food processing.
Amanda Jerrell, EE
Title: Engineering Department Assistant Manager, Electrical Engineer
School: Rose-Hulman Institute of Technology
Degree: B.S. Electrical Engineering
Duties: I handle all data collected for our arc flash hazard analysis – from training our field technicians to maintaining and improving our data collection standards, to quoting new projects, to assisting in keeping all of our deliverables up to the latest standards, to managing the technicians and handling their questions, comments, and concerns. I am the technical contact for customer service – if a customer has a technical question, chances are I’ll be the one they talk to. And in my spare time, I still do some arc flash analysis.
Industries: Since I’ve been here I’ve had a hand in most industries we’ve worked on – food processing, college campuses, aerospace, roofing and asphalt, water treatment facilities, plastics, bedding, paper products, cement, and the list goes on.
Brad Wiley, EE
Title: Electrical Engineer
School: Purdue University
Degree: B.S. Electrical and Computer Engineering Technology
Duties: Perform Arc Flash Studies on distribution systems to identify electrical safety hazards based on IEEE 1584 and NFPA 70E specifications. Recommend methods to ensure proper coordination of over-current protective devices and resolve device failure due to insufficient interrupt ratings. Field work includes data collection, report delivery and field technician training.
Industries: Power Generation Plants, Water Treatment Plants, Food Processing, Paper Mills
Joel Gibson, EE
Title: Electrical Engineer
School: Purdue School of Engineering and Technology, Indianapolis, IN
Degree: B.S. Electrical Engineering
Duties: Constructing a computer model of the electrical distribution system of the facility for analysis. Conduct short circuit studies for the system to determine if the interrupting rating of the system equipment is acceptable versus the calculated values. Construct TCC curves to provide analysis of system coordination. Conduct an arc flash analysis to determine category ratings throughout the electrical system and provide recommendations for lowering these levels.
Industries: Power generation, food processing, paper manufacturing facilities, wineries, theatres, warehouse, and aerospace.
Eric McCall, EE
Title: Electrical Engineer
School: Indiana University – Purdue University Indianapolis
Degree: B.S. Electrical Engineering
Duties include modeling a facility’s electrical system using SKM software and then performing system analyses to determine fault currents throughout the system for use in the arc flash evaluation. Produce system TCC curves to provide recommendations on system coordination. Provide final recommendations on equipment interrupting ratings and recommendations for reducing arc flash category ratings within the system.
Industries: Medical suppliers and corrugation, bedding, glass, and meat packaging plants.
Justin Sanders, EE
Title: Electrical Engineer
School: Purdue University
Degree: B.S. Electrical Engineering
Duties: Create a computer model of the electrical distribution system using SKM software. Analyze the system to determine fault currents and create TCC curves to improve system coordination. Perform arc flash analysis to determine category levels and recommend changes to the system to lower these levels.
Industries: Industrial manufacturing facilities, power generation, warehouses, schools
Carrie Burger
Title: Arc Flash Project Coordinator
Duties: As the Arc Flash Project Coordinator, I assemble the reports that the engineers have analyzed into a presentable book form and print the hazard labels. I am responsible for scheduling the data collection and delivery phases of the Arc Flash Study. I am a liaison between the engineering department and the customers.
Field Technicians
Our field technicians round out the Arc Flash Team. The field technician’s duties include travelling to customer facilities to collect data required for the arc flash analysis and again to deliver our final reports. During the data collection phase of a project, our technicians will use safe electrical work practices to determine appropriate Personal Protective Equipement (PPE) to wear while exposing energized electrical equipment. Data collected from the customer’s electrical system will include (but is not limited to) protective device types, sizes, settings, transformer nameplate data, generator and motor ratings, and conductor sizes and lengths. For the final report delivery phase, our technicians will return to the customer’s facility and present the Arc Flash Assessment Report. This phase will include a meeting to discuss the findings and recommendations presented within the report. Also, our field technicians will apply arc flash hazard warning labels to all equipment found to be a Category 1 or higher PPE requirement. Field technicians work closely with Engineering and our customers to ensure that the electrical system model built by Engineering is accura
