Hand guards are standard on phasing testers with Cat. No. 514500-1, and
514500-2. Cat. No. 514500-3 and 514500-4 testers have universal spline
fittings for attachment to hot line poles.
These phasing testers are designed for outdoor testing of grounded and
ungrounded systems. Applications for these instruments include checking
high-voltage fuses, testing for correct phase connections, and testing for
absence of high voltage on de-energized lines or apparatus. Note that the
movement of the pointer over the calibrated scale is only an indication of
the presence of voltage in the range indicated. Phasing testers are not to be
used for determining the exact voltage on the line or apparatus being tested.
The accuracy of the kilovolt indication is such that the nominal system
voltage shown by the indicator needle can be identified (either phase to
phase or phase to ground). The bandwidth covers the approximate spread
of system voltages in that range. Under most circumstances the needle will
fall within the appropriate band for the system under test; however, an
indication outside of the bands should not necessarily be construed as a
false reading. The difference between a phase-to-phase and a phase-to-ground
indication is easily discernible.
