Lange HVAC kabels werken beperkend bij het aansluiting van windparken

Met integraal ontwerp tussen windturbine kabel en net is een lange HVAC

kabel toch mogelijk

bull Today IEC 62067 and ICEA S-108-720 stipulates 20 ndash 300 Hz for After

Installation Test

o hellip but new edition of IEC 600603 stipulates 10 ndash 500 Hz for onsite testing

bull AC resonant equipment (ACRF) has been used below 20 Hz

bull Longer lengths (high C) and EHV (high U) need some degree of freedom

regarding frequency range WG B127 longer time duration at lower

voltages for factory acceptance and after installation tests compared to

IEC 62067 may be agreed

bull VLF-testing is not considered mature for HV and EHV

bull WG B127 recommends 10-500 Hz for routine factory acceptance and

tests after installation

bull The lower frequency limit of 10 Hz is important for testing of ldquolongrdquo

lengths

10 Hz 20

Hz

IEC 62067 prescribes 20 Hz as lower frequency limit for AC resonant

tests IEC 600603 prescribes 10 Hz The new lower frequency limit in

TB490 is set to 10 Hz giving insignificant change in breakdown strength

but a 4 times higher load capacity



17

Sample tests - In Electra 189 described as Special tests

When routine tests are not possible

Frequency of tests according to IEC except

If PD-test is not possible on rdquolong lengthrdquo (as defined by the WG) impulse and PD-tests

shall be performed on samples taken out from startstop of each extrusion run



18

For long submarine cables the water penetration tests are divided into three

tests

Conductor water penetration test LWPa

Metal sheath water penetration test LWPb

Radial water penetration test of joints RWP



19

Mechanical and thermal preconditioning

simulate actual installation conditions

Water propagation distance is not fixed

B127 recommendation lt 30 m

LWPa - conductor

Water ingress in the conductor during a cable fault at the

deepest part

LWPb - metal sheath

Water ingress under the metal sheath (reference is made to lead) at the near shore area

where the water pressure does not increase the ability to stop water penetration ( 30 m water

head)



20

Test on new installations are made when the installation has been

completed

If the complete installed length is too long a reduced test voltage with a

longer duration may be agreed Alternatively a voltage of Uo may be

applied for 24 hours

Time Domain Reflectometry (TDR) give a ldquofingerprintrdquo of the cable system

to be used if needed during the cable life
