Tests after installation - SANS 97

SANS 97: Electric cables-Impregnated paper-insulated metal-sheathed cables for rated voltages 3.3/3.3 kV to 19/33 kV (excluding pressure assisted cables)
Voltage test after laying, jointing and terminating for cables manufactured to this standard  as stipulated in Appendix A.3.3.

Voltage test for cables after laying, jointing and terminating

After cables manufactured in accordance with this standard have been laid, jointed and terminated, they can, if required, be subjected to the appropriate test voltage given in table below. The test voltage should be applied between conductors and between each conductor and metal sheath, which should be held at earth potential. In each case, the voltage should be increased steadily to the stipulated value and maintained at this level for 15 min.
