TR-BH Low Voltage Split Core Current Transformer Manufacturer for Measurement And Protection

Low-voltage current transformer(lv current transformer), with their accurate and reliable current measurement capabilities, are widely used in a variety of fields, including industry, construction, and healthcare, and are key components for circuit monitoring, control, and safety. In the industrial field, they are used for precise control and protection of electric motors, as well as for operation monitoring and energy management of facilities such as sewage pumping stations. Monitor the status of power distribution systems (especially low-voltage circuits) and provide data support for energy-saving control in buildings. In the medical field, to ensure the safe and stable operation of power circuits for medical equipment. For scenarios where current fluctuates drastically (e.g. new residential areas, rail transportation, manufacturing companies, etc.), wide-range low-voltage current transformers can accurately measure currents over a wide span of time by virtue of their excellent linearity and wide dynamic range, effectively avoiding saturation and precision degradation, and ensuring the accuracy of measurements and the safety of the system.
