Bobines & transformateurs en Français
Electrical transformers in theory and practice. A transformer generally consists of one or more coils (winding) of conducting wire, wound on a former (bobbin) that surrounds the centre limb (sometimes all limbs) of a circuit of magnetic material (core). The winding wires are insulated and the core is made from thin sheet steel plates known as laminations (this reduces 'eddy current' losses)

Transformers A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors — the transformer's coils. A varying current in the first or primary winding creates a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or "voltage" in the "secondary" winding. This effect is called mutual induction
Transformers Magnetism and Inductors, Magnetic Core Terminology, How a Transformer Works
Transformers a transformer is a device in which two circuits are coupled by a magnetic field that is linked to both. There is no conductive connection between the circuits, which may be at arbitrary constant potentials. Only changes in one circuit affect the other

Short circuit and open circuit tests of a transformer The equivalent circuit model for the non-ideal transformer, An ideal transformer with resistors and inductors in parallel and series replaces the non-ideal transformer. This model is called the high side equivalent circuit model because all parameters have been moved to the primary side of the ideal transformer

Time-delay relay reduces inrush current a transformer switching onto a line can sometimes cause a circuit breaker to trip or a fuse to blow. This phenomenon occurs even if the transformer presents no load, such as when the secondary is open. The problem arises because of the heavy magnetizing inrush current in the transformer
