three-circuit transformer
1Transformer — This article is about the electrical device. For the toy line franchise, see Transformers. For other uses, see Transformer (disambiguation). Pole mounted distribution transformer with center tapped secondary winding. This type of transformer is… …
2Three-phase electric power — This article deals with where, how and why three phase is used. For information on the basic mathematics and principles of three phase, see three phase. Three phase electric power is a common method of alternating current electric power… …
3Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the …
4Three-phase — This article deals with the basic mathematics and principles of three phase electricity. For information on where, how and why three phase is used, see three phase electric power. In electrical engineering, three phase electric power systems have …
5Delta-wye transformer — Not to be confused with Y Δ transform. A delta wye (Δ Y) transformer is a transformer that converts three phase electric power without a neutral wire into 3 phase power with a neutral wire. It can be a single three phase transformer, or built… …
6Current transformer — A CT for operation on a 110 kV grid In electrical engineering, a current transformer (CT) is used for measurement of electric currents. Current transformers, together with voltage transformers (VT) (potential transformers (PT)), are known as …
7Scott-T transformer — A Scott T Transformer (also called a Scott Connection) is a type of circuit used to derive two phase (2 φ) current from a three phase (3 φ) source or vice versa. The Scott connection evenly distributes a balanced load between the phases of the… …
8Phantom circuit — In telecommunication and electrical engineering, a phantom circuit is an electrical circuit derived from suitably arranged wires with one or more conductive paths being a circuit in itself and at the same time acting as one conductor of another… …
9Magnetic circuit — Magnetic Circuits Conventional Magnetic Circuits Magnetomotive force Magnetic flux Φ Magnetic reluctance Phasor Magnetic Circuits Complex reluctance Zμ …
10Variable frequency transformer — A variable frequency transformer is used to transmit electricity between two asynchronous alternating current domains. The VFT is a relatively recent development (first deployed in 2004). Most grid interties use high voltage direct current… …
