Network Connection Type Diagram Zigzag

5 the zigzag connection.

Network connection type diagram zigzag. Therefore this type of transformer or in some cases an auto transformer lends itself very well for establishing a neutral for an ungrounded 3 phase system. Many times this type of transformer or auto transformer will carry a fairly large rating yet physically be relatively small. We can see that both the ends are con nected together. Zig zag connection is sometimes desired as the disadvantages in star and delta connection can be overcome by the use of zig zag connection of transformer.

A zigzag transformer is a special purpose transformer with a zigzag or interconnected star winding connection such that each output is the vector sum of two 2 phases offset by 120. The zigzag connection is also called the interconnected star connection. See the diagram how connections are done to achieve a zigzag connection in the secondary. If you need to use dialup service you ll need a dialup modem and a telephone line.

Delta connection is indicated by d or d. Delta connection in the case of delta connection the ends of the windings are connected together as shown in the diagram. The zigzag transformer contains six coils on three cores. The first coil on each core is connected contrariwise to the second coil.

Many times this type of transformer or auto transformer will carry a fairly large rating yet physically be relatively small. With the zigzag connection the currents in the two halves of the windings on each leg of the transformer flow in opposite directions avoiding saturation. This connection has some of the features of the y and the connections combining the advantages of both. It is used as a grounding transformer creating a missing neutral connection from an ungrounded 3 phase system to permit the grounding of that neutral to an earth reference point.

Some computers have a built in dialup modem sometimes called a telephony modem. A broadband connection such as cable or dsl requires a broadband modem designed for that type of service and a cable tv or telephone line. The provider will usually rent you a modem so you don t have to buy it. 2 parallel zig zag attached to this post are two pictures one which show the 6 stators and 12 wires on the generator each wire labeled from 1 through 12 and the other which shows the wiring configurations for both options mentioned above.

The neutral formed by the zigzag connection is very stable. This connection type is used mainly for high rated cur rents and low voltages. To perform harmonic. The neutral formed by the zigzag connection is very stable.

We rarely use zigzag configurations for typical industrial or commercial use because they are more expensive to construct than conventional wye connected transformers.
