          New IEEE Standard - Inactive-Reserved.<br />\n
          Electronic devices that develop or utilize analog signals are not presently covered by standards. This Standard provides interface connectivity of modern power-system signal transducers based on electronics, such as magneto-optic current transducers, and electronic relays. The existing standardized levels from familiar magnetic current and voltage transformers are not readily generated by new types of electronic signal transducers.<br />\n
          \t\t\t\t<br />\n
          This standard defines the interface between voltage or current transducer systems or sensing systems with analog electronic outputs, and suitably designed protective relays or other substation measuring equipment. These transducer systems reproduce the power system waveforms as scaled values.<br />\n
          This standard also defines requirements for optional intermediate summing or ratio-adjusting amplifiers required to add or subtract the outputs of more than one sensing system for measurement by a single relay or measuring device.<br />\n
          The standardized measurement signal between the transducer system and the relay systems is characterized as an analog electrical signal of ±11.3 V peak, at a maximum power of 3.2 mW. A prime example of a sensing system with analog electronic output is an optical voltage or current sensing system with an optical-to-electronic interface. Figure 1 shows the typical configuration of system elements for an optical current sensing system in a high-voltage station. In this case the optical sensing systems are located on the bus at high potential. In other cases the sensing systems may be embedded inside power apparatus or insulators. The optical signal is transmitted through fiber-optic cables to the ground level before being converted to electrical signals scaled and formatted for use by protective relays and other intelligent electronic devices (IEDs). The optical-to-electrical conversion module is usually located in the control house, but may also be located near IEDs in the switchyard. This standard specifies the electrical signals between the optical-to-electrical conversion module and the relays or other IEDs using these signals.<br />\n
          The interaction between the optical sensing system and the conversion module is a proprietary scheme of a particular manufacturer's sensing design, not subject to standardization. It is the output of the conversion module, and therefore, the input of relays and other measuring functions, that is to be standardized here for interoperability. The marked section of Figure 1 shows the location of the interface defined in this standard.

          New IEEE Standard - Inactive-Reserved.<br />\n
          Electronic devices that develop or utilize analog signals are not presently covered by standards. This Standard provides interface connectivity of modern power-system signal transducers based on electronics, such as magneto-optic current transducers, and electronic relays. The existing standardized levels from familiar magnetic current and voltage transformers are not readily generated by new types of electronic signal transducers.<br />\n
          \t\t\t\t<br />\n
          This standard defines the interface between voltage or current transducer systems or sensing systems with analog electronic outputs, and suitably designed protective relays or other substation measuring equipment. These transducer systems reproduce the power system waveforms as scaled values.<br />\n
          This standard also defines requirements for optional intermediate summing or ratio-adjusting amplifiers required to add or subtract the outputs of more than one sensing system for measurement by a single relay or measuring device.<br />\n
          The standardized measurement signal between the transducer system and the relay systems is characterized as an analog electrical signal of ±11.3 V peak, at a maximum power of 3.2 mW. A prime example of a sensing system with analog electronic output is an optical voltage or current sensing system with an optical-to-electronic interface. Figure 1 shows the typical configuration of system elements for an optical current sensing system in a high-voltage station. In this case the optical sensing systems are located on the bus at high potential. In other cases the sensing systems may be embedded inside power apparatus or insulators. The optical signal is transmitted through fiber-optic cables to the ground level before being converted to electrical signals scaled and formatted for use by protective relays and other intelligent electronic devices (IEDs). The optical-to-electrical conversion module is usually located in the control house, but may also be located near IEDs in the switchyard. This standard specifies the electrical signals between the optical-to-electrical conversion module and the relays or other IEDs using these signals.<br />\n
          The interaction between the optical sensing system and the conversion module is a proprietary scheme of a particular manufacturer's sensing design, not subject to standardization. It is the output of the conversion module, and therefore, the input of relays and other measuring functions, that is to be standardized here for interoperability. The marked section of Figure 1 shows the location of the interface defined in this standard.

The existing standardized levels from familiar magnetic current and voltage transformers are not readily generated by new types of electronic signal transducers.<br />\n

          This standard specifies requirements for analog signals, emanating from electronic voltage and current transducers, that are inputted to protective relays. These requirements include signal level, frequency bandwidth, and dynamic range. The standard recognizes that other substation electronic devices utilizing voltage and current waveform measurements may connect to the same transducers.<br />\n
          The standardized measurement signal between the transducer system and the relay systems is characterized as an analog electrical signal of +/-11.3 V peak, at a maximum power of 3.2 mW.<br />\n
          A prime example of a sensing system with analog electronic output is an optical voltage or current sensing system with an optical-to-electronic interface. Figure 1 shows the typical configuration of system elements for an optical current sensing system in a high-voltage station. In this case the optical sensing systems are located on the bus at high potential. In other cases the sensing systems may be embedded inside power apparatus or insulators. The optical signal is transmitted through fiber-optic cables to the ground level before being converted to electrical signals scaled and formatted for use by protective relays and other intelligent electronic devices (IEDs). The optical-to-electrical conversion module is usually located in the control house, but may also be located near IEDs in the switchyard. This standard specifies the electrical signals between the optical-to-electrical conversion module and the relays or other IEDs using these signals.<br />\n
          The interaction between the optical sensing system and the conversion module is a proprietary scheme of a particular manufacturer's sensing design, not subject to standardization. It is the output of the conversion module, and therefore, the input of relays and other measuring functions, that is to be standardized here for interoperability. The marked section of Figure 1 shows the location of the interface defined in this standard.

          The standardized measurement signal between the transducer system and the relay systems is characterized as an analog electrical signal of +/-11.3 V peak, at a maximum power of 3.2 mW.<br />\n
          A prime example of a sensing system with analog electronic output is an optical voltage or current sensing system with an optical-to-electronic interface. Figure 1 shows the typical configuration of system elements for an optical current sensing system in a high-voltage station. In this case the optical sensing systems are located on the bus at high potential. In other cases the sensing systems may be embedded inside power apparatus or insulators. The optical signal is transmitted through fiber-optic cables to the ground level before being converted to electrical signals scaled and formatted for use by protective relays and other intelligent electronic devices (IEDs). The optical-to-electrical conversion module is usually located in the control house, but may also be located near IEDs in the switchyard. This standard specifies the electrical signals between the optical-to-electrical conversion module and the relays or other IEDs using these signals.<br />\n
          The interaction between the optical sensing system and the conversion module is a proprietary scheme of a particular manufacturer's sensing design, not subject to standardization. It is the output of the conversion module, and therefore, the input of relays and other measuring functions, that is to be standardized here for interoperability. The marked section of Figure 1 shows the location of the interface defined in this standard.

          The application guide for relay protection of squirrel-cage and wound-rotor induction motors presents a review of the generally accepted forms of motor protection and summarizes the use of relays and devices, singly and in combination, to enable the reader to properly select the necessary equipment to obtain adequate motor protection. The Guide is prepared primarily for the protection of three-phase integral-horsepower motors and refers to single- or two-phase motors only in special instances and only where specifically indicated. It is especially useful where the motor installation is sufficiently important, due to either its size or the consequences of motor malfunction, to justify specific design of the protective system. It also provides the information necessary to judge whether there are safety or economic reasons for such a specific design. This Guide is not a Standard and does not purport to detail the protective requirements of all motors in every situation. Its recommendation is of a general nature designed to cover the usual or typical motor installation. Sufficient background of material on objectives, application, and setting philosophy is presented, however, to enable the reader to evaluate the need for various forms of protection and to select and properly apply suitable protective equipment for most situations.

          This document has been developed as a guide for the design, installation, and protection of wire and cable systems in substations with the objective of minimizing cable failures and their consequences. This guide is not intended for use in the design of wire and cable systems in generating stations, which is adequately covered in IEEE Std 422-1986 and IEEE Std 690-1984. Guidance for wire and cable design for gas-insulated substations (GIS) is available in IEEE Std C37.122-1983 .<br />\n
          The purpose of this guide is to give guidance to the substation engineer in established practices for the application and installation of metallic and optical cables in electric power transmission and distribution substations. This guide emphasizes reliable electrical service during the design life of the substation. Solutions presented in this guide may not represent the only acceptable practices for resolutions of problems. This guide should not be referred to or used as an industry standard. It is being presented to aid in the development of wire and cable system installations and should not be taken as a compliance standard.

          This document has been developed as a guide for the design, installation, and protection of wire and cable systems in substations with the objective of minimizing cable failures and their consequences. This guide is not intended for use in the design of wire and cable systems in generating stations, which is adequately covered in IEEE Std 422-1986 and IEEE Std 690-1984. Guidance for wire and cable design for gas-insulated substations (GIS) is available in IEEE Std C37.122-1983 .<br />\n
          The purpose of this guide is to give guidance to the substation engineer in established practices for the application and installation of metallic and optical cables in electric power transmission and distribution substations. This guide emphasizes reliable electrical service during the design life of the substation. Solutions presented in this guide may not represent the only acceptable practices for resolutions of problems. This guide should not be referred to or used as an industry standard. It is being presented to aid in the development of wire and cable system installations and should not be taken as a compliance standard.
