Photoelectric light curves of eight single-line spectrum eclipsing binaries, generally regarded in the literature as sd-systems, have been reanalyzed by means of Wood's model in order to obtain homogeneous photometric elements. TW And, Y Cam, SW Cyg, WW Cyg, Y Psc, XZ Pup and X Tri are confirmed to be normal sd-systems. On the contrary, the new photometric solutions indicate that AI Dra should be classified as an sd-d system.
