Pre-Qualification Test of HVDC and HVAC Cables

STRI has two indoor test facilities for prequalification testing according to Cigré TB 496, IEC 60840 and IEC 62067. The tests can be performed either in a test hall or in an underground test facility, both with controlled environment.

Different media such as water, soil etc. can be introduced in the test circuit. Requirements such as snaking and ducts can also be introducted into the test circuit. Maximum test voltages are 650 kV AC and 1050 kV DC. Heating with either AC or DC current is available.
