The Polarity Phasing Device ( P.P.D.) is a Low voltage cable phasing system for use on de-energized conductors. The Polarity Phasing Device eliminates the confusion and errors in phasing when using headsets or other makeshift techniques. The POLARITY PHASING DEVICE uses 6 volt battery power to to establish a low voltage "polarized" detecting source on a cable conductor and uses an LED system to receive the polarized source.
