14/05741 HiPot AC/PD tests for cable systems 2015-2016
Energinet.dk intends to contract an independent, 3rd party to perform AC HiPot & PD commissioning testing on cable systems planned to be installed and commissioned in 2015, 2016 (and 2017).
The tests to be performed are AC HiPot tests executed in accordance with IEC 62 067 / IEC 60 840 at a voltage level of up to 1.7 x U0, for minimum one hour, or up to the time it takes to complete the number of cycles equal to 60 min at 50 Hz (180000 cycles).
The voltage applied shall be sinusoidal and have a frequency between 20 Hz and 300 Hz.
During AC HiPot test, Partial Discharge (PD) measurements shall be performed continuously at:
— The terminations on all cable systems to be tested.
— Joints of selected cable systems of particular strategic importance to the Danish transmission system.
PD testing of joints shall be performed on each joint using a daisy chained broadband PD system. Non-invasive partial discharge sensors must be delivered and permanently installed on the cable system.
The supplier shall come with the necessary equipment, including generator and resonance equipment to perform the tests described. The supplier shall furthermore perform the necessary analysis of the PD-measurements.
