HDE's TAG-5000 Wireless Phaser is designed to perform many of the existing functions of conventional voltmeter/phaser devices. However, the TAG-5000 uses state-of-the-art technology to eliminate the cord and lighten the weight of this important testing device. The TAG-5000 can be used for all overhead and underground phasing applications with appropriate underground probes and is ideal for use at higher voltages - up to 230kV - where safety and ease of use are prime considerations.
