In Memory

Our beloved colleague, Conrad R. St. Pierre, of Rotterdam, NY passed away on August 10, 2014. Born in Bath, Maine, Conrad received his Bachelors and Masters degrees from the University of Maine, later earning his second Masters degree from Union College. Conrad owned and operated his own business, Electrical Power Consultants, from 1996 until present. Previously he worked as managing electrical engineer at the General Electric Company for 26 years. Conrad also worked for Power Technologies, Inc (PTI)  for several years.

At the General Electric Company. Mr. St. Pierre’s work included design and application engineering for GE’s Medium Voltage Switchgear Department. This work involved the application, selection, and design of relay control circuits for switchgear to industrial and utility customers. Mr. St. Pierre joined the Industrial Power Systems Engineering Operation and worked in the field of conceptual design and system analysis of power systems for industries. He performed electrical power system studies for plants in the steel, chemical, automotive, paper, and aircraft industries, as well as commercial buildings, hospitals, and electric utilities. His particular emphasis was on short circuit, load flow, motor starting, harmonics, impact loading, stability, and load shedding analysis of electric power systems. He wrote and updated many computer programs used by GE on the above subjects. In 1986 he became Manager of IPSEO where he directed the activity of other engineers and was an instructor in the field of power system engineering. While at GE, he received several managerial and customer service awards, including the Industrial and Power System Engineering Award for Outstanding Technical Contribution to GE Industry Sales and Service.

Mr. St. Pierre joined Power Technologies, Inc (PTI) in 1991 as Manager of Industrial Power Systems performing similar analytical studies as he have done with GE. In addition, he increased PTI’s exposure and sales to the industrial market.

He was a member of IEEE and of several subcommittees, and was the Chairman of the Violet Book Working Group which deals with short circuit calculations. Mr. St. Pierre was a member of the U.S. National Committee of the International Electrotechnical Commission Technical Advisory Group for TC73/WG1 and WG2 concerning short circuit currents and calculation methods.

In 1997, Mr. St. Pierre formed his own analytical business known as Electric Power Consultants, LLC that provides analytical engineering services to his clients and clients of GE, ABB, PTI, Hanson Engineers, and ANNA, Inc.
