Description

High-Tech Specifications for Reliable Performance

The LST Three-Phase Integrated Current Transformer possesses a wide bandwidth and high accuracy, supporting precise measurement of current in a large frequency range with a standard operating frequency of 50 Hz. It can have multiple rated current ratios, including 5/5A, 10/5A, 20/5A, 50/5A, 100/5A, and 200/5A, meeting various system requirements. The accuracy classes are 0.2, 0.5, and 1.0, offered by the transformer for precise measurement for protection and also metering needs. With a rated burden ranging from 1 VA to 5 VA, it delivers performance across a broad spectrum of loads. In addition, the LST transformer comes with an insulation grade of 0.72/3 kV, short-time thermal current of 60 times the rated primary current (60 Ipr), and a rated dynamic current of 2.5 times the thermal current (2.5 Ith) for protection and stability when faults occur. They ensure compliance with IEC 61869 standards and hence provide engineers with a secure tool for system monitoring.

Versatile Applications in Power Distribution Systems

LST Three-Phase Integrated Current Transformer is specifically made for installation on three-phase bushings of ring main units (RMUs) and primary switches and is therefore an essential device in urban and industrial power grid distribution systems. It has good performance in the measurement of three-phase currents and zero-sequence currents and gives robust protection against ground faults in multi-cable circuits. This versatility makes it appropriate for application in renewable energy systems where accurate current data is necessary to facilitate grid synchronization and in traditional power grids where fault detection and system stability are required.

Key Benefits for Enhanced System Efficiency

The compact design of the LST transformer minimizes the installation space required and is well-suited for both new installations and retrofit installations in current systems where space constraints exist. The high degree of accuracy and wide bandwidth of the LST transformer enable system diagnostics, allowing engineers to identify future issues before they result in costly failures. Its nanocrystalline cores based on iron reduce energy losses, which improves efficiency overall, and the durability of the transformer ensures a longer service life in spite of any harsh conditions like high temperatures or changing loads, ultimately lowering maintenance costs and downtime.
