high potential test carried between line-line, line-
neurtal,line and neutral to graund on any control panelto
check insulation between live conductors and enclosure body
at hv like 1.5kv and onward depands on system voltage and
local standard, it is carried out also on control wiring too
e.g. from 300 to 600v it need 2.7kv test for 1 second and
2.4kv for 1 minuts,note when this test have to do test job
must disconnected from line voltage,it is most likely
megeer test, after testing it need to discharge tested line
to graund
