TLDR
The instrumentation setup for wireless condition monitoring of induction machine in a laboratory environment, where four parameters, viz., stator voltage, current, body temperature, and rotor speed were sensed and fed to a dedicated hardware unit.Abstract:
In this paper, we describe the instrumentation setup for wireless condition monitoring of induction machine in a laboratory environment. Four parameters, viz., stator voltage, current, body temperature, and rotor speed were sensed and fed to a dedicated hardware unit (DHU). This DHU was operated using commands from a desktop computer, acting as an operator station. An Arduino Uno board was used as the data collection unit of the DHU and interfacing to the ZigBee module. Data packets with all four sensed parameters of 5 s duration was continuously collected and transferred to the operator station for real-line display in a graphical user interface. All parameters had less than 1% error in their measurements.read more

Wind turbine condition monitoring by the approach of SCADA data analysis
TL;DR: In this article, the authors developed an effective method for processing raw SCADA data, and proposed an alternative condition monitoring technique based on investigating the correlations among relevant SCADA and realized the quantitative assessment of the health condition of a turbine under varying operational conditions, which has a potential powerful capability in detecting incipient wind turbine blade and drive train faults, but also exhibits an amazing ability in tracing their further deterioration.
