When facing the secondary side of a subtractive polarity transformer, which bushings are on the same side?

In a subtractive polarity transformer, the bushings are designated to indicate their connections and functions. The primary side is typically labeled with 'H' for high voltage, while the secondary side has 'X' for low voltage. In this case, when facing the secondary side of the transformer, the bushings x1 and x2 are the low voltage connections, while H1 is a high voltage connection on the primary side.

The correct pairing of bushings on the secondary side that are on the same side relates specifically to how they are connected. H1 and x1 are paired together because they correspond to the same phase on the transformer. They are configured to work together when considering the electrical flow and winding arrangement.

Additionally, keeping in mind the transformer connection setup, each bushing has its designated position and function. H1 being on the side of the primary winding and x1 being on the secondary winding indicates a strong alignment in terms of phase and voltage. This understanding is critical in ensuring the correct functioning of the transformer while preventing incorrect phasing which could lead to operational issues.
