REhase shift in auto-transformer

Hi,

I will like to know whether is there any phase shift betwween primary and secondary side of autotransformer. When a voltage transducer is connected to the secondary side of the autotransformer, will it able to detect the phase shift?

I seem to have some prob in detecting the zero-crossing of the secondary side of transformer.
 

Hello

To detect the zero cross you ca use an comparator and two diodes and 2 resistor to detect zero
