ECN Forum Forums Code Related Discussion NEC & other Code issues Static Line as Grounding conductor

Explain myself a bit better,
4160 & 13.8 Y sysyems Impedance (NGR) grounded Systems.
Start off underground 3 phases & Ground from equipment.
Then hit a pole Line go up pole Ground wire ties to Static Line runs lenght of pole line.
Drops back down to Ductbank ties back into 3 phases & ground wire.
Static line Grounded to ground rod at each pole.
CAN a static line be used for this Purpose????
This is all Feeders Owners Equipment.

I miss anything??

Yoop:

As I understand your question, IMHO, as long as the AWG of the 'static line' is compliant with the OCP, I see no reasoning why you can't use it. It is NOT a neutral.

Text from what I believe is the relevant Article (2011)
"250.186 Impedance Grounded Neutral Systems. Impedance
grounded neutral systems in which a grounding impedance,
usually a resistor, limits the ground-fault current
shall be permitted where all of the following conditions are
met:
(1) The conditions of maintenance and supervision ensure
that only qualified persons service the installation.
(2) Ground detectors are installed on the system.
(3) Line-to-neutral loads are not served.
Impedance grounded neutral systems shall comply with
the provisions of 250.186(A) through (D).
(A) Location. The grounding impedance shall be inserted
in the grounding electrode conductor between the grounding
electrode of the supply system and the neutral point of
the supply transformer or generator.
(B) Identified and Insulated. The neutral conductor of an
impedance grounded neutral system shall be identified, as
well as fully insulated with the same insulation as the phase
conductors.
(C) System Neutral Conductor Connection. The system
neutral conductor shall not be connected to ground, except
through the neutral grounding impedance.
(D) Equipment Grounding Conductors. Equipment
grounding conductors shall be permitted to be bare and
shall be electrically connected to the ground bus and
grounding electrode conductor.

Back to Question:
Can a Static Line Be used as A equipment Grounding conductor????
Remember on prints its noted as a STATIC Conductor.
Not a Equipment grounding conductor.
Might be OK I'd just like to see where thats Stated.

(Thanks for all the imput)

Yoop:

I did a quick search in the '08 handbook (CD) and got zero hits on static line. You (us) may have to dig into the NESC for this one. As I said above, I see no reason you can't use it as of now.

Theres different Definations for a Satic line & an Equipment Equipment grounding conductor.
Neither refers to the other.
The NEC is behind in the High Voltage Area.
Then throw in that its an Impeadence Grounding System.
That makes it even more interesting.
If you come up with anything conrete let me know John .

Yoop:

Have you looked thru the 2011 NEC, or the NESC?

I have NESC at work, time permitting tommorrow.....

'11 is in my car, maybe reading materials tonite.
