| 20140159754 | ESTIMATION OF RESISTANCE IN ELECTRICAL MACHINES - In an electrical machine which has unidirectional excitation applied to its windings, the mean values of voltage and current can be computed from the instantaneous phase voltage and current by the use of, for example, low-pass filters (in either the analogue or digital domain). The value of winding resistance can then be calculated by dividing the mean voltage by the mean current. This avoids the cost, fragility and potential inaccuracy of conventional temperature sensors, and provides the controller with an ongoing estimate of winding temperature. | 06-12-2014 |

The system can include a processor configured to receive the resistance data and the temperature data. Based on the received data, the processor can determine normalized resistance data accounting for temperature effects on the measured resistance. Normalized resistance data can indicate a predicted value for the insulation resistance measurement had the measurement been performed at a reference temperature. Thus, insulation resistance values normalized to a common temperature can be more accurately and meaningfully analyzed and trended over time. | 05-12-2016 |
