The Design Office of Transconverter developed the concept of high-voltage DC power supply for cathodic protection stations.

Due to application of high-voltage booster devices this concept reduces the required voltage level of the power transmission line. It allows to reduce the cost of high-voltage converters by given values of gas or oil pipeline length, mains cable section, the number and the output power of the cathodic protection station. The booster devices are part of the high-voltage converter which was based on the batch-produced converter HBU100 Y2.
