WebNov 4, 2024 · The KVA rating of Autotransformer is more than two winding transformers. For two-winding transformer, turns ratio a = V 1 − V 2 V 2 = N 1 − N 2 N 2. For Autotransformer, turns ratio a ′ = V 1 V 2 = N 1 N 2. Where N 1 = Number of primary turns of autotransformer. N 2 = number of secondary turns of autotransformer. Now, WebThe KVA transformed in the series winding equals the KVA transformed in the common winding. The capacity multiplication effect stems from the fact that the metallic … cytoband information
