Line matching unit ULS

         Line matching unit “ULS”

         (tunning device)

          Function

          Line matching unit  (“ULS”) is designed for galvanic isolation of high-frequency signals transmitted via high voltage power lines and subscriber equipment.

          “ULS” is designed to work with coupling capacitors, as well as with capacitive voltage transformers along power lines with voltage from 35 to 750 kV and through ground-wire line.

 

          "ULS" is able to solve the same problems that coupling device types of FP, FPM, FPU, FPMU, FPMR and others of similar purpose solve.

           It is manufactured on a modern technical basis, with tendency development and the needs of the energy industry.

           The transformers that are part of the device are manufactured on modern high-quality ferrite cores.

           Line matching unit are designed for high-frequency power of ?200 W
