On-line impedance analysis allows impedances of devices and power lines to be determined for the optimum design of PLC systems. By measuring changes in impedance of devices such as transformers, motors or power lines, impending failures may also be detected. This paper discusses software for the control, signal processing and calibration of the Inductive Shunt On-Line Impedance Analyzer. The paper...
Negative sequence current monitoring is a well-known application that capable of identifying stator faults in induction motor using a simple measurement technique. However, the technique is sensitive to other asymmetrical sources of negative sequence, faults or disturbances. This paper addresses the issues on negative sequence condition monitoring based on such sources. The paper provides a comprehensive...
