The Schneider Electric TeSys LT6 protection relay is a versatile solution designed to safeguard against various electrical anomalies. From thermal overloads to phase imbalance and earth leakage current, this relay offers comprehensive protection, ensuring the safety and reliability of electrical systems. The front panel features a 7-segment display unit for viewing protection faults, along with intuitive controls such as test and reset pushbuttons, DIP switch, and serial interface, enhancing operational convenience. Additionally, it offers fault and alarm indication via a remote display unit, enhancing monitoring and control capabilities. With communication via bus using Uni-Telway and Jbus/Modbus protocols, it facilitates seamless integration and data exchange, including measurements, logs, and configuration parameters. To complement this system, the LT6CT2001 current transformer, with a 200:1 ratio and class 5P accuracy, ensures precise and reliable current measurement, further enhancing the functionality of the TeSys LT6 protection relay.
