Isolation transformer. In classical transformers, there are two electrically separate windings of wire coils around the transformer's core. The advantage of transformer-type over other types of balun is that the electrically separate windings for input and output allow these baluns to connect circuits whose ground-level voltages are subject to ground loops or are otherwise electrically ...
"Balun" is a generic name for any transformer configured specifically to connect between balanced (non-grounded) and unbalanced (grounded) circuits. They can be made using any transformer type, but the actual balance achieved depends on the type; for example, "choke" baluns produce balanced current and autotransformer-type baluns produce ...
A circuit that has the specific purpose of allowing interfacing between balanced and unbalanced circuits is called a balun. A balun could be a transformer with one leg earthed on the unbalanced side as described in the transformer balance section above. Other circuits are possible such as autotransformers or active circuits. [4]
A balun can be implemented as a transformer which also allows for an impedance transformation. This is usually wound on a ferrite toroidal core. The toroid core material must be suitable for the frequency of use, and in a transmitting antenna it must be of sufficient size to avoid saturation. [21] Other balun designs are mentioned below.

Thus 1 = 30°, 2 = 60°, 3 = 90°, 6 = 180° and 12 = 0° or 360°. According to the IEC60076-1 standard, the notation is HV-LV in sequence. For example, a step-up transformer with a delta-connected primary and a wye-connected secondary is still labeled as 'Yd1'. The 1 indicates the LV winding lags the HV by 30 degrees. [1]
