Ideal For
Not Recommended For
For single-phase power transformers, follow IEC 60076 terminal markings. Primary terminals: A and B for 10kV or 6kV input. Secondary terminals: 1a and 1n for control output. Ground the secondary winding at one point. Never short-circuit the secondary while energized. Ensure proper fusing on primary side.
