Center tap capacity of a center tapped delta secondary
Applies to Transformers by SquareD/Schneider Electric
Center tap capacity must be calculated from the overall kVA capacity of the Transformer
The capacity of a delta - delta center tapped Tansformer`s center tap is simply 5% of the Transformer`s nameplate kVA capacity. For example, if the Transformer is an EE75T6HCT, which is a 75kVA device, the center tap capacity is 5% of 75kVA, or 3.75kVA. 3.75kVA at 120V calculates to 31.25 amps. However, newer design Transformers by SquareD/Schneider Electric, such as an EE75T151HCT can have a center tap capacity of up to 30%, or 22.5kVA. 22.5kVA at 120V calculates to 187.5A.
