CAN/CSA-C22.3 NO. 8-M91 (R2003)
Railway Electrification Guidelines
Product Details
Preface
This is the second edition of No. 8 in a Series of Standards issued under Part III of the Canadian Electrical Code. It supersedes the first edition, published as a Preliminary Standard in 1986.
Development of these guidelines was initiated by Transport Canada's Transportation Development Centre and by the Railway Association of Canada in anticipation of the need to electrify long distance rail lines.
This Standard contains guidelines on the power supply and overhead distribution system as well as on grounding and interference with communications and signalling systems. It is recognized that this edition does not cover all aspects and that some of the quantitative values included must be taken as preliminary, being still under consideration nationally and internationally. The Committee believed that making the guidelines available with these deficiencies was preferable to waiting for resolution of the outstanding issues. The Committee continues to encourage comment and further work towards resolution of the guidelines.
Appendix A is not a mandatory part of the guidelines, but provides a bibliography of papers that were referred to by the Committee.
This Standard was prepared by the Technical Committee on Railway Electrification Guidelines under the jurisdiction of the Standards Steering Committee on the CE Code, Part III, and was formally approved by these Committees. It has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
1.1
This Standard applies to the overhead contact system and traction power supply to the locomotive, using a single-phase alternating supply at 25 or 50 kV nominal voltage, 60 Hz.
1.2
This Standard has been written primarily for use in the development of conventional railway freight and passenger services. However, the use of the Standard is recommended for development of special services, such as rapid transit, wherever possible.
1.3
This Standard covers design considerations in the following selected areas of railway electrification:
(a) insulation coordination and electrical clearance;
(b) vertical and horizontal clearances;
(c) overhead contact systems;
(d) interference with railway signalling circuits;
(e) interference with communication circuits;
(f) utility interface-unbalance and harmonics; and
(g) grounding and bonding.
It is not intended to be a complete guideline on railway electrification.
1.4
The recommendations and comments contained in this Standard do not constitute complete design or construction specifications and are for guidance only.
1.5
Conditions not covered by this Standard may be governed by the appropriate requirements or other documents in common use or as required by constituted authority.
1.6
In addition to the reference publications listed in Clause 2.3, the standards and guidelines of the American Railway Engineering Association (AREA), the Association of American Railroads (AAR), the International Electrotechnical Commission (IEC), and the Union International des Chemins de Fer (UIC) may be used in areas not included in this Standard.
