ABSTRACT
James H. Harlow is self-employed as principal of Harlow Engineering Associates, consulting to the electric power industry since 1996. Prior to this, he had 34 years of industry experience with Siemens (and its predecessor company Allis-Chalmers) and Beckwith Electric. While at these –rms, he managed or conducted groundbreaking projects that blended electronics into power transformer applications. Two such projects were the introduction of the –rst microprocessor-based intelligent electronic device used in quantity in utility substation environments (for the automatic control of load tap changers) and a power-thyristor-based load tap changer to accomplish arc mitigation during the tap change event in step-voltage regulators.
