              Revision Standard - Superseded - Draft.<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 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.

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.

              Revision Standard - Superseded - Draft.<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 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.

              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 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.
