2、6110-82 2Term Definition 1 . G E N E R A L C O N C E P T S 1.1. Transformer Static electromagnetic device having two or more inductively coupled windings. This device is designed for conversion of one or several a

3、c (alternating current) systems into one or several other ac systems by means of electromagnetic induction. 1.2. Power transformer The transformer designed for conversion of electric power in electric networks and i

4、n installations that are used for reception and consumption of electric power. N o t e . Three-phase and poly-phase transformers with power no less than 6.3 kV·A and the single- phase transformers with power no

5、less than 5 kV·A shall be defined as power transformers. 1.3. Power transformer unit The device that contains two or more power transformers united in one structure. 1.4. Poly-phase transformer group The group o

6、f single-phase transformers with windings connected in the way to create an ac system within each winding of this group. The number of phases of the system shall be equal to the number of transformers. N o t e . Poly

7、-phase transformer group that contains three single-phase transformers shall be defined as the three-phase transformer group. 1.5. Magnetic field of the transformer Magnetic field that is created in the transformer

8、 by means of magnetomotive forces caused by all its windings and by other parts with ac current. N o t e . Magnetic field of the transformer may be conditionally divided into interdependent components: the main f

9、ield, the winding leakage field, the field of zero-sequence currents, etc. This division may be used for calculation, for determination of parameters and for carrying out a research. 1.6. Winding leakage field

10、 The component of magnetic field of the transformer created only by the part of magnetomotive forces caused by all its main windings: the vector sum of these forces shall be equal to zero within each winding ph
