The L10P005D15 is a current transformer (CT) designed for the protection and monitoring of electrical systems. It is a robust and reliable 4-terminal device that provides reliable measurements of AC currents with a library of integrated features. The transformer provides high accuracy current measurements up to 100A in a wide range of applications. The L10P005D15 is a class A current transformer, meaning it meets the accuracy requirements of IEC 61850, the global standard for communication systems in power grids.

The four terminals of the CT provide isolated connections for the primary current output, secondary current output (or inputs), and two reference/ground points. The transformer provides a variety of input and output ranges, offering flexibility for measurements in different systems. As a current transformer, the L10P005D15 is able to accurately measure AC currents in switchgear and protection systems, as well as current levels in frequent heavy-duty communications systems. Additionally, the low-noise design of the CT helps reduce common power-supply and differential noise.

To power the transformer, a common-mode DC voltage is applied to the second and fourth terminals. This enables the measuring device to work with non-grounded line configuration, saving setup time and eliminating the need for additional clamps. Internally, the L10P005D15 features a high-resolution core with high saturation, which provides precise measurements even in high-loaded systems. The performance of the transformer is further improved by its anti-aliasing filter which limits the effect of harmonics.

The L10P005D15 provides integrated data outputs with high accuracy. The open-loop voltage and power signals of the transformer are transmitted through isolated outputs to a detection device, such as a power meter, for further analysis. The transformer also provides a variety of common features, including linearity, temperature compensation, and protection against short-circuits. Furthermore, the device has a built-in device temperature sensing (DTS) module that ensures safety and stability of the transformer.

The L10P005D15 is a well-designed current transformer that offers reliable measurement and high accuracy for switchgear, communications systems, and power systems. The transformer is easy to install and offers a library of features that make it suitable for demanding applications. Furthermore, its high saturation core and integrated features provide accurate readings in busy operations. With its low-noise design, the transformer is an ideal choice for protection and monitoring applications in power systems.
