Generatortech is the world’s leading authority on field winding shorted turns detection.

Generatortech, Inc. was established in 1989 by Mr. Donald R. Albright, who originally developed and refined methods for acquiring and analyzing air-gap flux probe data during his time at General Electric in the early 1970s.

At GE, Mr. Albright recognized that assessing rotors for shorted turns was tremendously important for generator owners. Initial flux probe tests were done off-line, but with the rotor at rated speed and the stator windings short-circuited. Realizing that on-line testing would be more useful to the industry, Mr. Albright developed testing techniques that could detect single shorts in each rotor coil while the generator load was varied. This testing identified the locations of each coil with shorted turns (Pole and Coil), as well as determining the number of shorts in each affected coil.

Upon retirement, Mr. Albright returned to GE as a consultant to develop GE’s competency to provide and install flux probes and train their technical staff how to analyze the results.

After a few years consulting to GE, Mr. Albright wanted to more aggressively market the flux probes. Recognizing that the use of air-gap flux probes was a critical need for the power industry, he formed Generatortech, Inc., dealing exclusively in the use of air-gap flux probes for assessing generator rotor shorted turn conditions. 

We continue to refine and improve the technology, software, and hardware. Throughout the world (more than 65 countries), the name Generatortech has become synonymous with air-gap flux probes and shorted turn detection.
