Dr. Prigmore is a licensed Electrical Engineer with expertise in the fields of power systems, power electronics, power markets, arc flash and arc blast, short-circuits, power system protection, fuses, circuit breakers, relays, magnetics, electromagnetics, rotating electrical machinery (motors and generators), electrical current sensing technologies, semiconductor device applications, explosives, HAZMAT shipping regulations, microcontrollers, circuit board analysis, high power lab testing, standards testing, standards development and compliance. He has eight years’ experience in developing and implementing short-circuit current limitation techniques and devices, which, includes novel concepts of, fault current limiters and solid-state circuit breakers in addition to traditional techniques. He has evaluated power systems and commissioned their components on six continents for a wide range of industries, including mining, petrochemical, pulp and paper mills, and renewable energy installations. Dr. Prigmore has the training necessary to climb wind turbines.

Dr. Prigmore’s experience while at Exponent consists of performing arc flash hazard analysis, short-circuit studies, load flow studies, and protection coordination studies. He has performed thorough electrical analysis on wind turbines, which included a comparison of the wind turbine components and their installation to the National Electric Code, arc flash hazard analysis, protection coordination and has investigated wind turbine failures including fires. He has investigated electrical power generator failure modes, provided recommendations on maintenance procedures and has recommended protection devices for both large electrical power generators and smaller consumer electronic motors. In addition, he has investigated transformer failures.

Dr. Prigmore has advised utilities on interconnection plans and screening criteria of distributed energy resources for renewable energy installations such as solar farms and wind farms.

He has performed arc flash hazard studies and advised clients on recommended solutions to reduce the incident energy site wide. He has performed load flow studies and short-circuit studies for power systems and is experienced in system protection coordination. He has experience in designing high voltage power transmission lines and performed protection coordination studies low, medium and high voltage. He has designed, analyzed and type tested current limiting fuses for both low and medium voltage systems.

He has designed wide-band, high accuracy current transformers and has developed Rogowksi coils that can measure electrical currents over 100,000A with greater than 99 percent accuracy in industrial applications. Dr. Prigmore has performed numerous heat runs and dielectric tests on low and medium voltage equipment as well as numerous tests, analysis and improvements on analog control circuitry designs. He has experience performing and leading high power tests on industrial equipment in accordance with IEEE/ANSI, IEC and UL standards. In addition, Dr. Prigmore has experience in hardware design for integrating a small scale solar farm and battery storage into a microgrid. He has programmed novel control algorithms using microcontrollers and FPGAs. He has also designed a GUI for a controllable thermostat incorporating human factor principles.

Prior to joining Exponent, he was a member of the system protection division from G&W Electric, an electrical switchgear manufacturer. He was responsible for sales, marketing, application engineering, R&D, manufacturing improvements, field service and troubleshooting. Dr. Prigmore was instrumental in developing a product that was deemed a “Product of the Year” winner in the Electrical Safety Category from Plant Engineering Magazine for its significant improvement in the reduction of incident energy levels in arc flash and arc blast hazardous electrical systems vs. existing technologies.

Dr. Prigmore is the chair for the IEEE Industrial Application Society’s Early Career Development Subcommittee and he is a voting member of the IEEE Region 4 Power and Energy Society’s Scholarship Committee. He is a voting member for the standard committee of IEEE P1584 (Guide for Performing Arc Flash Hazard Calculations) and is a chapter chair to the CIGRE “Green Book” on Fault Current Limiters. He has also authored a chapter on High Voltage Direct Current (HVDC).

Dr. Prigmore is proficient in EasyPower, ETAP, SKM, MATLAB/Simulink, PLECS, LabVIEW, PSCAD, ARCAD, C, VBA and PowerWorld. He has experience with Code Composer Studio, Arduino, SABER, Pspice, and AMPL software.
