How Transformers work. This module describes how transformers work, and how the design of both the transformer coils, and the core on which they are wound affects the efficiency of the transformer. Detailed descriptions of many types of transformer are also given together with typical applications. Isolation Transformers can allow separate circuits to be physically isolated from each other

The vault-type transformer (Fig. 15.5) may be installed in a vault under a sidewalk or in a building. They are often used in underground electric network areas. Submersible single-phase distribution transformers (Fig. 15.6) are used in some under-ground systems installed in residential areas, as described in Chap. 34. Corrosion problems and the high cost of installation have minimized the use

Distribution Transformer Construction. Two types of construction are the core type and the shell type. In the core type, the core is in the form of a rectangular frame with the coils placed on the two vertical sides (Fig. 15.8). The coils are cylindrical and relatively long. They are divided, part of each primary and secondary being on each of the two vertical legs. In the shell type (Fig. 15

A novel diagnosis technology based on transistor operating point analysis is presented. This technology is the way to detect penetration current net result from fault, replace the net with impedance net, calculate voltage value of each node of the impedance net by OHM’s low, and then sequentially trace the fault logic propagation.
