Preface
C22.3 No. 6 sets forth methods of electrical coordination between pipelines and overhead AC electricity supply lines having line-to-ground voltages greater than 35 kV installed as follows:
(a) a pipeline located on a power line right-of-way, and vice versa;
(b) a pipeline right-of-way located parallel to a power line right-of-way, where the adjacent boundaries are at or within 100 m of each other, and vice versa; and
(c) laterals and extensions to the pipelines described in Item (a) or (b) above.
This Standard describes mutual interference effects and specifies methods that, when used in the design, construction, operation, and maintenance of piplelines and powerlines, will reduce these effects.
Scope
1.1
This Standard sets forth methods of electrical coordination between pipelines and alternating current (ac) supply lines having line-to-ground voltages greater than 35 kV, simultaneously or separately installed as follows:
(a) a pipeline located on a power line right-of-way, and vice versa;
(b) a pipeline right-of-way located parallel to a power line right-of-way, where the adjacent boundaries are at or within 100 m of each other, and vice versa; and
(c) laterals and extensions to the pipelines described in Item (a) or (b) above.
Hereinafter referred to as power line.
1.2
This Standard describes mutual interference effects and specifies methods that, when used in the design, construction, operation, and maintenance of either facility, will reduce these effects.
1.3
This Standard prescribes acceptable interference levels and minimum required separation between facilities.
1.4
The requirements of this Standard may also be applied to piping in refineries, tank farms, compressor and metering stations, and similar facilities.
1.5
This Standard contains requirements supplementary to the requirements of CSA Standards Z183, Z184, CAN/CSA-C22.3 No. 1, and C22.3 No. 4.
