这是一个可搜索的PDF。1.范围和概述本标准的规定体现了适用于在供电或通信系统运营机构之间进行电气协调的原则和实践，这些机构的网络之间存在或预计存在干扰。该标准为经验丰富的人员提供电力和通信系统的影响和敏感性指导。本标准旨在帮助解决不同公司之间出现的协调问题。本标准并不旨在约束拥有和运营可能相互干扰的电力和通信设施的单个公司。 不包括与电气化铁路（CSA标准C22.3第8号）和管道（CSA标准C22.3第6号）相关的电气协调。在多个省份运营的加拿大铁路属于加拿大议会的立法权限，并受《铁路安全法》的约束，该法由加拿大运输部管理。根据《铁路安全法》以及加拿大运输部的命令、法规和判决，联邦管辖下的铁路需要建设、运营和维护其设施。本标准阐述了由于两个系统之间的电、磁和导电耦合（包括相互连接和接地），在直流至17 kHz的频率范围内对电力系统的影响。 （虽然本标准涵盖的频率高达17 kHz，但目前关于超过3 kHz的频率的信息很少。）包括电力系统的正常运行，包括电源相位不平衡，以及异常或故障情况。（CSA标准C22.3第5.1号规定了电力和通信设施之间的物理接触。）讨论了架空和地下电力设施以及电力系统终端设备对干扰的影响。特别排除在使用电压（低于750 V）下运行的电力线，以及建筑物或商业和工业厂房内遇到的干扰。 通信设施包括所有电线和电缆配置（同轴电缆、双绞线、屏蔽电缆、带金属组件的光纤电缆、开放式电线等），单个电路以模拟或数字模式运行。实现电力、电信和铁路公司之间的最佳电气协调，可以显著降低解决相互之间的电气干扰问题的总体成本。目前，各个电力和通信公司之间存在解决电气协调问题的各种行政和技术安排，但仅限于其共同管辖范围内。 这些协议通常基于当地和传统的设计参数值，通过长期应用，这些参数值已被接受为操作目标或标准。在许多情况下，通过遵循此处包含的指南，这些双边协议可以得到显著改进。本标准允许对现有或拟建电力和通信设施的以下数量进行解释:（a）基波、谐波和其他非谐波频率下的功率影响；（b） 纵向噪声或对地噪声；（c） 电力和通信线路之间的相互耦合；（d） 纵向感应60赫兹电压； （e） 金属或正常模式噪声；（f） 电缆平衡；和（g）地电位升高（GPE），包括任何直流偏移。本标准总结了与电气协调相关的技术问题，并提出了一些典型问题的解决方案。详细讨论了相关电气参数的协调级别和应用说明，并提出了一种方法，旨在促进电力公司和通信公司在其共同管辖范围内实现最佳电气协调。在存在干扰或预计会发生干扰的情况下，在启动任何预防或联合缓解行动之前，干扰应超出既定的可容忍目标或协调水平。 如果需要缓解，则提供反映技术和管理问题的指南，以实现最佳总体解决方案。

This is a searchable PDF.1. Scope and OverviewThe provisions of this Standard embody the principles and practices applicable for the purpose of effecting electrical coordination between organizations that operate electric supply or communications systems, where interference exists or is expected to exist between their networks. The Standard provides experienced personnel with influence and susceptibility guidance for power and communications systems. This Standard has been developed to help resolve coordination problems that arise between different companies. The Standard is not intended to constrain an individual company that owns and operates both power and communication facilities that may interfere with each other. Electrical coordination associated with electrified railways (CSA Standard C22.3 No. 8) and pipelines (CSA Standard C22.3 No. 6) is not included.Railways in Canada operating in more than one province come within the legislative authority of the Parliament of Canada and are subject to the Railway Safety Act, which is administered by Transport Canada. Railways under federal jurisdiction are required to construct, operate, and maintain their facilities in accordance with the Railway Safety Act and the orders, regulations, and judgements of Transport Canada.This Standard addresses power system influence over the frequency range from dc to 17 kHz, due to electric, magnetic, and conductive coupling between the two systems, including mutual bonding and grounding. (While this Standard covers frequencies up to 17 kHz, little information is currently available for values over 3 kHz.) Normal power system operation, including power phase unbalances, is covered, as well as abnormal or fault conditions. (Physical contact between power and communication facilities is addressed in CSA Standard C22.3 No. 5. 1.) Interference due to overhead and underground power facilities is addressed, as well as power system terminal equipment, to the extent that this equipment can affect the interference.Power lines operating at utilization voltages (below 750 V) are specifically excluded, along with interference experienced inside buildings or commercial and industrial plants. Communication facilities include all wire and cable configurations (coaxial cables, twisted pair, shielded cables, fibre-optic cables with metallic components, open wire, etc) with individual circuits operating in either an analog or digital mode.The achievement of optimum electrical coordination between power, telecommunication, and railway companies may significantly reduce the overall costs of solving their mutual problems of electrical interference.Various administrative and technical arrangements addressing electrical coordination issues currently exist between individual power and communication companies, but only within their common jurisdictional boundaries. These agreements are generally based on local and traditional design parameter values that have become accepted as operational objectives or standards, through their long-term application. In many cases, these bilateral agreements could be significantly improved by following the guidelines included here.This Standard will permit the interpretation of the following quantities, for existing or proposed power and communication facilities: (a) power influence, at the fundamental, harmonic, and other nonharmonic frequencies; (b) longitudinal noise or noise-to-ground; (c) mutual coupling between power and communication lines; (d) longitudinally induced 60 Hz voltage; (e) metallic, or normal mode, noise; (f) cable balance; and (g) ground potential rise (GPE), including any dc offset.This Standard summarizes the technical issues associated with electrical coordination and presents some solutions for typical problems. Coordination levels for the relevant electrical parameters, with application notes, are discussed in detail, and an approach is presented that is intended to facilitate the development of optimal electrical coordination between a power utility and a communication company within the boundaries of their joint jurisdiction. In cases where interference exists, or is expected to occur, it should be beyond the established tolerable objective or coordination levels before any preventive or joint mitigative action is initiated. If mitigation is required, guidelines reflecting both technical and administrative issues are provided for achieving the optimum overall solution.
