Types and Construction of Power and Distribution …

Dry-type transformers operate in air or gas rather than being liquid filled. Just like with liquid transformers, the air or gas serves as an insulating medium and also to dissipate heat from the windings. The two general types of construction are the open or ventilated dry-type transformer and the sealed or closed-tank type.

power transformer construction - the core

Power Transformer Construction - The Core

There are two basic types of core construction used in power transformers: core form and shell form. In core-form construction,there is a single path for the magnetic circuit. Figure 1 shows a schematic of a single-phase core, with the arrows showing the magnetic path.

classification of transformers family

Classification of Transformers Family

The transformer types could be classified according to their power rating, voltage, current, weight, type of cooling etc., but such approach would have a limited applicability. Probably the simplest and the clearest transformer classification is according to the number of phases in:

potential transformer (pt) - circuit globe

Potential Transformer (PT) - Circuit Globe

The potential transformer is mainly classified into two types, i.e., the conventional wound types (electromagnetic types) and the capacitor voltage potential transformers. The potential transformer may be defined as an instrument transformer used for the transformation of voltage from a higher value to the lower value.
