About Sumatron

The company was founded by its principal engineer, Tom Baker in 1982, based on patents for revenue metering and is a California State Corporation.  Sumatron is currently engaged in the electrical power engineering support of large nuclear, coal, oil, and gas generating stations with an emphasis on plant and high voltage interconnection protective relay systems.  Baker has reviewed over 35,000 megawatts of large generating station protective relay designs and settings for both new construction and existing plants.  In 2002, Sumatron cooperated in the design of a software program with the founder’s son, John Baker, BS Computer Science, that automates the tedious calculations associated with both generating station protective relay settings, and plant engineering support.   By 2004, the company cooperated with Dr. Isidor Kerszenbaum to develop a test instrument that would detect shorted turns in large generator cylindrical rotor generator field windings that is currently being used in the Americas, Asia, Europe and Africa.

The software performs 132 different calculations and each one has a graphic associated with it that illustrates the circuitry, formulas, and references.  In 2005, it was decided to incorporate the software graphics into a 4-day comprehensive electrical power engineering Power Point training seminar.  By 2006, Sumatron partnered with IEEE to secure continuing educational credit for seminar attendees.  Since then, the training program continues to be enhanced with Baker’s 2011 CRC Press book entitled “Electrical Calculations and Guidelines for Generating Stations and Industrial Plants” and an IEEE paper “Improving BES Reliability at Large Generating Station Locations” that was presented at the 2014 Texas A&M University Conference for Protective Relay Engineers.  In 2017 the 2nd edition of Baker’s CRC Press book was published. Sumatron is currently working on the 2nd version of the EE Helper Power Engineering software program which will automate the computations for more than 200 calculations.
