Our Response - Use ofResistive Temperature

Much debate and misinformation has been published in various technical journals and in the marketplace on the use of Resistive Temperature Deteetor (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 Blectrica1 Insulation is made. I. INTRODUCTION Four new case studies are presented. to once again substantiate the use of this technology. One case study compares signals from an RID that is installed. in the same slot as a Stator Slot Coupler (SSC). A point by point response to the paper referenced in the abstract is not made, however, the conclusions of the 2006 paper are analyzed, and appropriate responses given.
