KONCAR-Institute-Rotor Winding Fault Detection Sensor
The document provides a detailed specification of the Rotor Winding Fault Detection Sensor (RWFDS) developed by KONČAR – Electrical Engineering Institute Inc. This sensor is designed for detecting inter-coil short circuits in rotor excitation winding using the differential magnetic field measurement method (DMFM).
The RWFDS features a one-channel acquisition unit with a real-time controller, with options for multiple channels upon request.
The system includes a voltage input for magnetic field sensors and a digital output for alarms and warnings.
Communication is facilitated through RS-232, with wireless options available on request.
LED indicators are used for power supply and digital outputs, and data is logged using flash memory.
The device operates on a power supply of 24 ± 10% VDC, consuming 50 mA.
The operational temperature range is from -25°C to +85°C.
The RWFDS complies with EMC immunity/emission standards (EN 61000-6-4) and vibration/shock resistance standards (EN 60068-2-6/EN 60068-2-27/29).
The sensor is designed to be installed on machine housing.
The RWFDS offers on-line analysis, digital output for alarms, and waveform extraction for detailed analysis. It uses two magnetic field sensors embedded on the stator within the machine air gap to enhance detection accuracy and cost-effectiveness compared to similar systems.

ROTOR WINDING FAULT DETECTION SENSOR RWFDS represents a new concept in rotor winding fault detection. This smart sensor enables detection of inter coil short circuits in rotor excitation winding based on the differential magnetic field measurement method (DMFM) inside the machine air gap. The DMFM method eliminates the contribution of the magnetic field present in the symmetric machine from the measuring signal and in that way the output signal depends only on the magnetic field produced by the fault. By using two magnetic field sensors embedded on the stator, inside the machine air gap, RWFDS...
