IEC TR3 61334-1-2:1997 采用配电线载波系统的配电自动化 第1-2部分:一般考虑 规范的指南

This technical report of type 3 is intended to offer useful information to design a distribution automation system (DAS) using distribution line carrier (DLC) systems for a specific application. For the sake of clarity, the information, useful to design a DAS using DLC systems for a specific application, has been subdivided into three main steps: - the first step concerns the strategic choices determining the architecture of the DAS (clause 3); - the second step deals with the specification of the application processes and the related operational parameters (clause 4); - the third step refers to the facilities that both processing and transmission equipment have to provide in order to cope with the application needs (clause 5). Clause 6 is dedicated to a general valuation of different coupling methods. Clause 7 is instead dedicated to the quality assurance procedures in order to meet the application needs included in a DLC system. Moreover, this technical report contains two annexes: - annex A containing the comparison and evaluation of two different modulation techniques (narrow-band FSK modulation and wide-band modulation); - annex B containing the general outline of a quality plan.

DIN EN 61334-3-21:1997 配电线路载波系统的配电自动化.第3部分:电力线信号要求.第21节:MV 两线之间的专用的电容耦合装置

The document applies only to MV phase-to-phase isolated capacitive coupling devices for MV (medium voltage) distribution line carrier (DLC) systems. The coupling devices ensures: a) the efficient transmission/reception of carrier-frequency signals between the DLC-transceiver and the power line; b) the safety of personnel and the protection of the low-voltage parts of the installation against the effects of the power-frequency voltage and transient overvoltages.

CSA T510-1995(R2007) 带环路信令的电话机的性能和兼容性要求

1. Scope 1.1 Purpose This Standard provides performance and compatibility requirements for telephone sets intended for direct tip and ring connection to central office (CO) or private branch exchange (PBX) lines. The requirements are based on present telecommunications plant characteristics at the telephone set interface. These requirements should ensure satisfactory voice-grade service to the user in a high percentage of installations, both initially and over a period of time. However, owing to the wide range of switching equipment, customer apparatus, and loop plant (eg, some subscriber carrier systems), conformance with this Standard does not guarantee acceptable performance or interface compatibility under all possible operating conditions. In general, where two levels of acceptability are specified (desirable and mandatory), compliance with the criteria in the desirable category implies a higher probability of acceptable performance or compatibility. 1.2 Application 1.2.1 These requirements apply to a telephone set intended for single-party service; however, at any one location, one or more telephone sets may be connected to the line. When multiple telephone sets are connected to a line it is assumed that only one set is off-hook at a time. If more than one telephone set is off-hook at a time, the resulting service over the network may not be satisfactory in all respects. These requirements apply also to a telephone set intended for connection to the standard station interface on a PBX as specified in CSA Standard T512 and EIA/TIA-464A. 1.2.2 A telephone set complies with this Standard if it meets the requirements when manufactured and can be expected to continue to meet these requirements when properly used and maintained. 1.2.3 This Standard applies to equipment for general application and selected application telephones. The latter may not be suitable in all applications, eg, where such a telephone set is the sole instrument at a particular location. These requirements are not intended to describe specific requirements for the following types of telephones. However, the general transmission, signalling, and impedance requirements are applicable for equipment such as (a) telephones used with data sets; (b) coin telephones; and (c) emergency special purpose telephones, or other public or semipublic telephones (eg, mine, elevator, and public emergency telephones). 1.3 Limitations 1.3.1 Electromagnetic Interference (EMI) This Standard does not include EMI requirements. 1.3.2 User Safety This Standard does not include requirements for user safety. The applicable Standards for user safety of telecommunications terminal equipment can be found in the Canadian Electrical Code, Parts I and II, and UL Standard 1459, Standard for Telephone Equipment. 1.3.3 Network Protection Equipment that meets the requirements of this Standard may not necessarily comply with network protection standards mandated by various levels of government. This Standard is intended to be in conformity with Part 68 of the FCC Rules and CS-03 of Industry Canada, but it is not limited to the scope of those rules.

CAN/CSA-T510-1992 电话机的性能和兼容性要求

1.1 Purpose This Standard provides performance and compatibility requirements for telephone sets intended for direct tip and ring connection to Central Office (CO) or Private Branch Exchange (PBX) lines. The requirements are based on present telecommunications plant characteristics at the telephone set interface. These requirements should ensure satisfactory voice-grade service to the user in a high percentage of installations, both initially and over some period of time. However, owing to the wide range of switching equipment, customer apparatus, and loop plant (eg, some subscriber carrier systems) used in Canada, conformance with this Standard does not guarantee acceptable performance or interface compatibility under all possible operating conditions. 1.2 Application 1.2.1 These requirements apply to a telephone set intended for single-party service; however, at any one location, one or more telephone sets may be connected to the line. When multiple telephone sets are connected to a line it is assumed that only one set is off-hook at a time. If more than one telephone set is off-hook at a time, the resulting service over the network may not be satisfactory in all respects. These requirements apply also to a telephone set intended for connection to the standard station interface on a PBX as defined in CSA Standard T512; however, these requirements do not apply to a proprietary telephone set. 1.2.2 A telephone set complies with this Standard if it meets the requirements when manufactured and can be expected to continue to meet these requirements when properly used and maintained. 1.2.3 This Standard applies to equipment for general application and selected application telephones. The latter may not be suitable in all applications, eg, where such a telephone set is the sole instrument at a particular location. 1.3 Limitations 1.3.1 Electromagnetic Interference (EMI) This Standard does not include EMI requirements. General EMI requirements may be found in CSA Standard C108.8 and are not considered a mandatory prerequisite to this Standard. 1.3.2 User Safety This Standard does not include requirements for user safety. The applicable Standards for user safety of telecommunications terminal equipment can be found in the Canadian Electrical Code, Parts I and II. 1.3.3 Network Protection Equipment that meets the requirements of this Standard may not necessarily comply with network protection standards mandated by various levels of government.
