WebJan 30, 2024 · It’s a dual-winding transformer. The primary winding has a branching head used to change the arc ignition voltage. Also, a tap button is used to change the secondary side’s no-load voltage. The primary and secondary windings are connected separately to the two iron core legs. In this way, the transformer will have a larger leakage reactor. http://www.stocktonca.gov/bfDocs/UW21010_Attachment%20B%20-%20Specification%20Section%20261113.pdf WebMulti tap transformers can be single phase or three phase. These transformers can provide voltage regulation and compensate for the line voltage drop. Each tap means different turns in the winding and different current transformation ratios. So, multi tap transformers are flexible for numerous applications. eicher motors ltd share
