The advanced modeling tools and innovative equipment developed by Jinliang He is making drastic improvements in protecting high-voltage power transmission lines from the effects of lightning strikes. Using electromagnetic field theory, He developed lightning shielding failure analysis methods for extra- and ultra-high-voltage transmission lines that are more accurate than conventional electrogeometric analysis. Tackling the difficult subject of upward lightning leaders originating from the transmission lines, He’s models more accurately simulate the real process of a lightning strike, enabling optimal design of overhead power lines to reduce lightning shielding failure events. He also pioneered polymeric surge arrestors that are smaller, lighter, and safer to better suppress overvoltage due to lightning strikes and to effectively reduce the cost of constructing ultra-high-voltage systems.
An IEEE Fellow, He is the Chang Jiang Scholars Distinguished Professor of China’s Ministry of Education with the Department of Electrical Engineering at Tsinghua University, Beijing, China.
George Dorwart Rockefeller’s prescient work on how to use computers to provide real-time analysis of voltages and currents for fault detection laid the foundation for today’s digital protection, control, and monitoring of the electric power grid. Known as “the father of digital protection,” Rockefeller invented the concept of on-line, real-time protective relaying of electric power systems in 1967 while with Westinghouse Electric Corporation—well before the advent of microprocessors made it a cost-effective reality. His development of the Prodar 70 digital relay, installed in a California transmission substation in 1971 by Westinghouse and Pacific Gas and Electric, transformed protective relaying of power systems and set the standards for modern microprocessor relay products. Rockefeller’s contributions inspired the industry to look at protection and control in a completely new, and smarter, way.
An IEEE Life Fellow, Rockefeller is retired and works as an engineering consultant, New York, NY, USA.
George Anders’ expertise has contributed toward setting the standard for rating electric power cables, which has provided significant economic benefits to the power industry. His computational techniques using analytical and finite element methods enable engineers to accurately rate cable circuits. He also developed optimization techniques for selecting the most economic conductor sizes, providing accurate calculations to avoid costly oversizing of buried cables. The software for steady-state and emergency ratings of underground cables, which he developed, is used throughout the world and is considered the industry standard for power cable rating calculations. Anders’ contributions to early leak detection methods are also helping to reduce the costs of detection, location, clean up, and repair related to cable leaks.

A pioneer in exploring the potential of SF6 (sulfur hexafluoride) as a dielectric insulator, Wolfram Boeck provided the power industry with technology that enables reliable and efficient high-capacity electricity transmission. Prof. Boeck’s research on SF6 began in the 1960s, resulting in the first gas-insulated, hermetically encapsulated high-voltage switchgear. He addressed key aspects of SF6 as an insulting gas, including development of the “volume time law” that describes time lag as a function of stressed gas. Prof. Boeck also investigated insulation coordination and methods for avoiding external effects and for monitoring insulation quality using UHF signals. He championed the implementation of SF6 in practical devices and standards, resulting in space-efficient gas-insulated substations and reliable gas-insulated transmission lines, which have been implemented worldwide as safe methods for supplying power.
An IEEE Fellow, Dr. Boeck is a Professor Emeritus with the Technische Universität München, and lives in Meersburg, Germany.
Willem Boone’s pioneering diagnostic and condition-assessment methods for power cables have been invaluable to the electric power industry in determining product life and avoiding electrical failure. Among Mr. Boone’s major contributions was his development of testing methods to detect water treeing in both aged and new cables. Water treeing can advance degradation and lead to electrical failure in buried or water-immersed high-voltage cables. Mr. Boone’s methods aide utility companies in determining when to replace existing cables. For testing new cables, he created a high-frequency (500 Hz) accelerated method, which reduced the ageing test duration to 4 months compared to approximately 2 years. Mr. Boone has also improved partial discharge detection tools helpful in estimating remaining cable life, and he has been very active in preparing related international user guides and standards within CIGRE, IEC, and ICC.
An IEEE Senior Member, Willem Boone is a senior consultant with KEMA, now called DNV GL, Oosterbeek, The Netherlands.

Michel Duval is an internationally renowned leader in the field of dissolved gas analysis (DGA) for condition monitoring of oil-filled power equipment such as high-voltage transformers. Condition monitoring helps prevent service failures and aids power companies in asset management of critical equipment. One of the most reliable techniques for recognizing abnormal behavior in transformers while the equipment is in operation, DGA’s use as a standard method for condition monitoring is largely due to the efforts of Dr. Duval. The “Duval Triangle” method has become an indispensable tool for DGA and is used by hundreds of power utilities, service laboratories, and manufacturers of on-line gas monitors. Dr. Duval also established the typical levels of gas formation observed in various types of electrical equipment and the probability of equipment failure as a function of in-service gas formation. His gas-in-oil standards have been commercialized since 1999 and are used worldwide.
An IEEE Life Fellow, Dr. Duval is currently a senior research scientist with Hydro Quebec Institute of Research, Quebec, Canada.
Carlos Katz’s vital research on moisture prevention in power cables has extended product life by over 25 years and has saved the utility industry substantial money worldwide. As Extruded cables insulated with cross-linked polyethylene (XLPE) and ethylene propylene rubber (EPR) age, moisture diffuses into their insulation and, in the presence of electric stress, a degradation phenomenon originates. It was Mr. Katz’s research that helped discover and explain the moisture phenomenon (known as “water trees”), and it was his efforts that led to a solution. Mr. Katz developed a method that involved running dielectric liquids through the inter-strand spacing of the aged cables. The liquids diffuse into the insulation to replace the moisture, inhibiting further development of water trees and allowing continued operation.
An IEEE Life Fellow, Mr. Katz is currently the president of Cable Technology Laboratories, Inc. in New Brunswick, NJ, which provides testing services to manufacturers and utility companies to assure cable system reliability.
