If standing on the high-voltage side of a three-phase transformer, where will the H1 bushing be positioned?

When discussing the orientation of transformer bushings, particularly in a three-phase transformer, it's essential to understand the standard configurations used in power systems. The H1 bushing is typically designated as the high-voltage connection point and is conventionally positioned to facilitate the proper electrical phase arrangement.

In a three-phase transformer, the H1 bushing is generally located on the right side. This position allows for clear designation and ensures that the high-voltage output aligns with the correct phase sequence when connected to other equipment in the system. The right-side placement of the H1 bushing is part of the universal standard, which helps in maintaining consistency and safety during installation and maintenance procedures.

Understanding this configuration is crucial for personnel involved in substation maintenance, as it ensures proper connections and reduces the risk of confusion that might arise from non-standard arrangements.
