On-Site Testing of 66 kV Subsea Array Cables for Off-Shore Windfarms

Abstract

Off-shore windfarms with extruded XLPE inter array cables with ratings up to 66 kV will be more and more common. IEC is anticipating the situation with a new standard IEC 63026 (under development) to guide manufacturers, test service providers and operators is under development. This paper discusses the kind of application of this standard and the practical implication in the field. A test system to cover the requirements is proposed and the test methodology analyzed and discussed in depth.
