Stator Core Measurement Upgrade Option CPC 100 upgrade option for electromagnetic imperfection testing on rotating electrical machines Our Stator Core Measurement Upgrade Option is used together with our CPC 100 multi-functional testing device. Together they perform time-saving and highly reliable electromagnetic imperfection testing (also known as stray flux measurements) on stator cores of rotating electrical machines, including hydro and turbo generators, as well as motors. The importance of stator core testing Electromagnetic imperfection testing is performed to detect stator core interlamination faults that can cause overheating and damage in rotating machines during operation. During the measurement, the stator core is energized with a small percentage of nominal flux and the stray flux on the surface is measured by a Chattock coil. Any change in the stray flux is an indication of a potential fault between two or more layers. To avoid down times, regular measurements are recommended to compare and evaluate the insulation integrity between stator core layers over time. Efficient, user-friendly solution The measurement sensor is mounted on a rail and automatically moves across the stator core to scan the surface. After one slot is finished, the rail is manually moved to the next slot. The entire stator core is semi-automatically scanned using this approach. This ensures efficient and highly reproducible measurements. The user-friendly Primary Test Manager (PTM) software provides users with a guided workflow throughout the test and enables a real-time graphical analysis of the results. A heat map with adjustable limits provides you with a visual overview of hot spots in the stator.
