TapBR-SSM: High-Resolution Segmentation and Longitudinal Ellipse-Normalized Contour Analysis of an On-Load Tap-Changer Component

An on-load tap changer (OLTC) regulates transformer voltage under load, while repeated portable imaging provides records of accessible component geometry. This study proposes TapBR-SSM, which combines high-resolution HRNet features, stage-selective Mamba-inspired directional refi...
