Transformer terminals marked x1 and x2 are indicative of which terminals?

The terminals marked x1 and x2 on a transformer are indicative of the secondary terminals. This designation is standard in transformer schematics, where primary terminals are often denoted as p1 and p2, while secondary terminals are labeled x1 and x2. The secondary side is where the transformer delivers its output voltage to the load, transforming the electrical energy from the primary winding into a different voltage level according to the turns ratio.

In typical transformer operation, the primary winding is connected to the input source, and the secondary winding supplies power, often at a different voltage suitable for the application. Knowing this distinction is vital for linemen and electrical workers when connecting or troubleshooting transformer systems, ensuring proper voltage management and safety procedures.
