Transformer contact TSRD
The TSRD is an electronic device developed to minimize or prevent inrush currents in three-phase transformers. It enables a smooth switch-on by gradually increasing the supply voltage. The TSRD is primarily used in industrial plants, power distribution systems and switchgear where three-phase transformers are used. By using the TSRD, inrush currents can be reduced, which improves the efficiency and service life of the transformers and stabilizes the electrical system.
