Customer Question

After the power source (13.2K volts AC) has been removed, what properties does the residual voltage left in each of the 3 phase conductors, type 1/C (one conductor /phase), size 2 AWG with XLPE insulation, and a length of 700 feet through EMT Conduit, still have?
Is this a capacitance charge or static electric?
Since there is no source is it now DC? Is that why the ticker do not show voltage present? How can it be measured or just ground it out?
If there enough of a charge to sustain a shock that can disrupt a person's heart if the current travels the correct path though the body?

I am not a lineman, but what I can tell you is this. Ground it out when its shut down. There is enough of a static charge to kill you. You want all three phases grounded out to eachother and ground before doing any work on this.

Can voltage be measurered? What PPE level would it be? How does instuated wire act like a capacitor?

I suggest posting these questions individually. But to answer your final question, by definition a capacitor is two conductor separated by a dielectric (insulator), which is exactly what you have when you have more than one wire in a metal raceway!
