6.3 D.C. High voltage test shall be made after installation on the<br />
following:-<br />
1) All 1000 Volts grade cables in which straight through joints have<br />
been made.<br />
2) All cables above 1100 V grade. For record purposes test data shall<br />
include the measure values of leakage current verses time.<br />
The D.C. High voltage test shall be performed as detailed below in<br />
the presence of the Engineer-in-charge or his authorized<br />
representative only.<br />
Cables shall be installed in final position with all the straight<br />
through joints complete. Terminations shall be kept unfinished so<br />
that motors, switchgears, transformers etc. are not subjected to<br />
