JWG 31 - TC 18/JWG 31

IEC/IEEE 61886-2:2025 is applicable to three-phase and single-phase liquid immersed subsea power transformers (including auto-transformers) with at least one winding with rated voltages in the range 3,6 ≤ Um ≤ 245 kV and with rated power in the range 50 kVA to 300 MVA. The intention is to specify additional requirements that are not covered by the IEC 60076 series and IEEE Std C57.12TM series.
