As we are dealing with high voltage it is critical that the
correct procedure is used. 1/ A switching sheet should be
used to ensure that both sides of the test point is
isolated locked and tagged, 2/ A Modiwak (HV sensor) should
then be tested on a known live source first then the
isolated point should be tested and the Modiwak should then
be retested on the known live source, this ensures that the
Modiwak is functional, 3/ Then dressed in the correct PPE
earths may be installed, making sure the the earths are of
a size for the fault level at that point.
All the previous answers are partly correct but to prevent
accidents it is esential that a strict procedure is used.
