When comparing current transformers (CT) and potential transformers (PT), the CT PT difference becomes clear through their transformation ratios and winding structures. Both transformers serve essential roles in electrical measurement but differ significantly in design and functionality.
Transformation Ratio: The Core Difference
The most noticeable CT PT difference is the transformation ratio. In a current transformer, the transformation ratio is high, as it is designed to reduce high currents to a manageable level for accurate measurement. This allows the CT to handle large currents safely. On the other hand, potential transformers have a low transformation ratio. They are designed to step down high voltage levels to a much lower value, suitable for measurement. This difference in transformation ratios is critical in determining the application of each transformer in electrical systems.
Primary and Secondary Windings: Key Structural Differences
Another major CT PT difference lies in the structure of the primary and secondary windings. In current transformers, the primary winding has fewer turns and carries the current that needs to be measured. The secondary winding, however, has many turns to step down the current, making it safe and measurable for instruments. In contrast, potential transformers have a primary winding with more turns to carry the high voltage. The secondary winding in PTs, with fewer turns, is connected to the measurement instruments for voltage reading. This structural difference ensures that both transformers fulfill their unique roles effectively.
