Current transformer 100/5A Ø22, class 0.2s TI-100-5-02S

Current transformer for precise measurements

This single-phase current transformer with a closed core is a reliable tool for converting high currents into safe and readable values for measuring devices. Designed for use in both industrial installations and energy consumption monitoring systems, it ensures accuracy and safety of measurements. The TI-100-5-02S model is distinguished by its accuracy class of 0.2S confirmed by a calibration certificate from an accredited laboratory, which guarantees the reliability of readings.

Construction and application

The current transformer finds wide application in measurement circuits where it is necessary to monitor large current intensities. Its construction based on a closed core ensures stability and precision of measurements. The current-carrying conductor flows through the transformer aperture, inducing a secondary current proportional to the primary current. This transformed signal is then transmitted to control and measuring devices, enabling accurate reading and data analysis. This transformer is particularly useful in overvoltage protection systems and in applications requiring precise load monitoring.
