Recommendations for testing DC extruded cable systems for power transmission at a rated voltage up to 500 kV (this TB replaces TB 219)

In 2003, TB 219 was issued to give recommendations for testing HVDC extruded cables up to 250 kV. The trend for higher voltage levels in DC extruded cables systems resulted in a need for new test recommendations covering the highest voltage levels. Based on same principles as TB 219, this new Technical Brochure provides recommendations for the following tests on extruded cables for DC power transmission systems up to 500 kV : development test, prequalification test, type test, routine test, sample test and after installation test.
