ABSTRACT:
Apparatus for performing a variety of tests, including phase matching, detection of open phases and energized
ot energized verification, on primary distribution cables. The apparatus is operable from a location which is physically remote from the primary distribution cables under test and does not require an ohmic contact to such lines, thereby substantially enhancing the safety of such testing.
