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

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

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

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)

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

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

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
After installation test
TenneT is de eerste grensoverschrijdende
elektriciteitstransporteur van Europa
Met 20000 kilometer aan hoogspannings-
verbindingen en 36 miljoen eindgebruikers
in Nederland en Duitsland behoren we tot
de top 5 elektriciteitstransporteurs van Europa
Onze focus is gericht op de ontwikkeling
van een Noordwest-Europese energiemarkt
en op de integratie van duurzame energie

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

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

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)
