: The current power cables IEC standards do not provide adequate recommendations for after-laying testing and diagnosis of offshore export and inter-array power cables. However the standards IEEE 400 and IEEE 400.4 recommend partial discharge monitored testing, e.g., by continuous or damped AC voltages (DAC). Based on the international experiences, as collected in more than 20 years at different power grids, this contribution focuses on the use of DAC for after-laying testing and diagnosis of submarine power cables both the export and inter-array cables. Higher risk of failure, long unavailability, higher repair costs, and maintenance costs imply that advanced quality control is becoming more important. The current state of the existing and drafting international standards are based on onshore experiences and not related to the actual serious problems experienced with failures on export up to 230 kV and inter-array cables up to 66 kV. The application of damped AC as a testing solution in this concern is specially discussed. The advantages of this testing technique, in combination with actual testing examples, show the findings on export and inter-array cables at offshore wind farms.

“…The localization of single defects along a cable has traditionally been done using the observations of the time of arrival (ToA) of the original PD pulse and its subsequent reflections to the sensors, the wave propagation speed and the total length of the cables [19], [20]. This time domain reflectometry (TDR) technique is usually implemented using one-end measurements (single sensor) or two-ends measurements (two sensors) [21], [22]. A combined use of TDR and frequency domain reflectometry (FDR) has also been proposed to improve the localization capabilities of the TDR [23].…”

“…DAC technique has proven to be an efficient tool for on-site PD detection in power cables [25,26]. The basic operation principle of this technique is to charge the cable with a high-voltage (HV) DC source and discharge the cable with an inductor and a solid-state HV switch [27]. The solid-state HV switch is made up of series connected semiconductor devices, usually insulated-gate bipolar transistor (IGBT) or light triggered thyristor (LTT) discrete [28][29][30].…”
