measure voltages by connecting a voltmeter between the two sides. If the lines are in
Figure 5-2. Phasing Check Using Hot-Stick Phasing Testers
Check phases A,B,C,1,2,3
individually by moving
contact hook to ensure
each phase is energized
and reaches appropriate
Jumper the hotsticks across
the open switch and check
each phase, A-1, B-2, and C-3.
If circuits are in phase, the
voltmeter will register zero.
Connect all phases as necessary
for all connections to register zero.
Line Fault Locators. Use line fault locators on underground lines up to 34.5
kilovolts to determine the location of line faults.
