Partial Discharge Detection in High Voltage Rotating Machines Capacitive coupler. Stator slot coupler. A comparison of these sensors is described in the following. Table 1 comparisons of various electrical PD detection sensors. LATEST PD DETECTORS IN MARKET. Given below is the list of manufactures of PD detection equipment: IRIS Power Engineering (North America) ADWEL International Limited (Canada) Jurnal Teknologi Full paper - core.ac.uk in stator winding of a generator is an on line partial discharge monitoring system. This system will sense deterioration of winding insulation in the form of voltage sensed by Stator Slot Coupler (SSC) that is installed in the generator2. However, there might be interference signals that will distort Short-Slot Hybrid Coupler in Gap Waveguides at 38 GHz short-slot hybrid coupler in rectangular waveguides. Chapter 3 mainly concerns the theoretical and analytical approach behind gap waveguides technology. It shows the required designing techniques and similarities with conventional technologies. Most of the text and figures are taken from the research papers assesment of stator winding insulation - part 1 final ...
connected a chamber comprising a pipe-like extension ll of the horn, a metallic iris diaphragm interposed in a transverse conductor although there are a variety of other absorber structures that may be used equally well.
The operating bandwidth of Stator Slot Couplers is 10-1000 MHz at the 3 dB cut-off; The Stator Slot Coupler is designed with a dual output to distinguish slot partial discharges from endwinding partial discharges; The Stator Slot Coupler is 2.0 mm thick with a width that is manufactured to the generator specification for slot width and length.
