Our response — use of Resistive Temperature Detector as partial discharge sensors in rotating equipment

Much debate and misinformation has been published in various technical journals and in the marketplace on the use of resistive temperature detector (RTDs) as a sensor of partial discharges (PD) in motors and generators. The authors have more experience in this field of technology than any other company in the world. With hundreds of applications working in operating facilities and thousands of data records, this technology is well proven. This paper addresses the concerns in using RTDs as a PD sensor through sound technical analysis and case studies. Specific response to the paper titled "investigations into the use of temperature detectors as stator winding partial discharge detectors" presented at the 2006 IEEE International Symposium on Electrical Insulation is made.
