Reclamation Information Sharing Environment (RISE)

In previous research, a method of slow-roll testing that could map partial discharge activity in large diameter rotating machines was shown to be feasible and a prototype was built. In other work, the Electromagnetic Rotor Turner (EMRT) was developed as a prototypical device for electrically turning rotating machines offline for routine maintenance and slow-roll testing. The subject research, along with one other research project, extended the EMRT capability to a more functional system called the Rotor Turning Test Suite (RTTS). The RTTS is designed to incorporate all types of slow-roll testing, including the method described here: rotor installed partial discharge mapping of large diameter hydro generators. This project builds on this concept by acquiring dedicated equipment for partial discharge mapping and developing an efficient path forward for adoption of this technology throughout Reclamation.
