The Rotor Health Monitor from Accumetrics Associates Inc., Schenectady, NY, allows operators of brushless AC motors and generators to continuously monitor ground fault resistance, rotor temperatures, field winding resistance, and average winding temperature. The monitor provides quantitative ground fault resistance values for trending or alarms, ground fault location indication, RTD sensor measurements for up to 12 RTDs at specific locations, average winding temperature computed from field resistance (calculated from live measurements of field voltage and current), PC display and data storage capability, and alarm relay contact outputs.
