EUROPE-WIDE AWARDING OF THE SUPPLY OF DEMARCATION UNITS FOR THE PROTECTION OF RAW POWER SYSTEMS AGAINST EXCESSIVE CONTACT VOLTAGES IN THE NEGOTIATED PROCEDURE ACCORDING TO SEKTVO

terranets-bw GmbH operates a large gas pipeline network and wants this pipeline system

effectively protect against excessive contact voltages. The high

Contact voltages result from the inductive coupling of the sections

parallel running 110kV / 220kV / 380kV (50Hz) high voltage and 110kV

16.7 Hz traction current and 15kV traction power lines. To protect the gas pipes.
