Parallel bridges on the tap selector connection contacts are then mandatory if the tap winding has been wound in two or more branches and each of these branch taps is connected to the contacts of the tap selector. This measure reliably prevents the following: ▪ Introduction of circulating currents into the current paths of tap selector and diverter switch ▪ Commutating arc on movable tap selector contact bridges ▪ Overvoltage between adjacent tap selector connection contacts con- nected in parallel 3.2 On-load tap-changer combination VACUTAP® VRC I/VR II / VRF I/VRF II for delta connection The on-load tap-changers VRC II 402, VRF II 1302 and VRG II 1302 can al- so be used with the single-pole on-load tap-changers VRC I 401, VRF I 1301 and VRG I 1301 as two-column on-load tap-changer combinations VRC I 401/VRC II 402, VRF I 1301/VRF II 1302 and VRG I 1301/ VRG II 1302 to set the voltage for transformer windings in delta connections (the same is true with VRC I 551/VRC II 552 und VRC I 701/VRC II 702).
