5. Equipment categories For equipment containing powerline communications (PLC) or broadband communications (BPL) capability, PLC and BPL modems should be considered as a separate part of the equipment. This subpart of the smart grid communications device should be tested according to national regulations. In the absence of such regulations, the device should be tested in accordance with IEEE Std 1775. 1 1 F 11 5.1 1 6 B In-premises communications equipment This class includes stationary equipment in weatherprotected environments. In-premises equipment may be connected sensors and couplers connected to low or medium-voltage lines. In addition to communications equipment, such equipment may include auxiliary equipment such as listed in 5.4. 5.2 1 7 B Distribution line communications equipment This class includes stationary equipment in non-weatherprotected environments. In addition to communications equipment, such equipment may include auxiliary equipment such as listed in 5.4. 5.3 1 8 B Generation, transmission, and substation communications equipment This class includes stationary equipment in non-weatherprotected environments subject to elevated levels of electromagnetic fields. The manufacturer should specify whether the equipment is rated for that standard’s surge withstand capability (SWC) tests as Class 1 or Class 2 per Annex A of IEEE Std 1613.1. During the period that the SWC tests are applied, Class 1 equipment may experience communications disruptions or errors, while for Class 2 equipment, the communications should not be disrupted nor experience errors. Electric utilities should select equipment that conforms to a class that is appropriate for each application.
5.4.3 Communications couplers These include capacitive and inductive couplers for use on all voltage levels. 5.4.4 Partial discharge couplers These include capacitive, inductive, acoustic, and other couplers and sensors for use on all voltage levels. 6. Performance criteria This section provides guidelines for selecting clearly defined performance criteria in order to determine if the equipment under test (EUT) is affected by various tests during testing. The manufacturer specification may include appropriate performance criteria of the EUT, such as:  Bit rate  Block error rate  Throughput  Rate of re-transmissions The EUT should operate without protocol failure, loss of link, or degradation of any other functions relevant to the end user. Degradation in performance of the EUT is defined relative to the manufacturer’s performance specification. When the EUT contains substantial system performance and functional criteria beyond this basic list, the testing organization may need to consider the application of additional software testing standards such as IEEE Std 1012 or ISO/IEC/IEEE 29119. The following performance criteria are taken from EN 61000-6-1.
