17.1.1 The requirements for testing are given in Pt 6, Ch 2, 21.1 Testing of the Rules for Ships, which are to be complied
with where applicable. Additions or amendments to these requirements are given in
the following paragraph(s) of this sub-Section.
17.1.2 For equipment operating at voltages above 15 kV a.c. testing should be in
accordance with relevant International or National Standards acceptable to LR and is
to be based on approved test schedules.
NOTES
- For high voltage cables up to 36 kV a.c., high voltage testing
may be carried out in accordance with IEC 60502 (all parts), Power cables
with extruded insulation and their accessories for rated voltages from 1
kV (Um = 1,2 kV) up to 30 kV (Um = 36 kV).
- For high voltage cables up to 69 kV a.c., high voltage testing
may be carried out in accordance with IEEE Std. 400.2, IEEE Guide for
Field Testing of Shielded Power Cable Systems Using Very Low Frequency
(VLF) (less than 1 Hz).
17.1.4 When it is desired to make additional high voltage tests on equipment
which has already passed its tests, the voltage of such additional tests is to be 80
per cent of the test voltage the equipment has already passed. It is to be ensured
that the test voltage is above the operation voltage.
