C37.90.1-2002 - IEEE Standard Surge Withstand Capability (SWC) Tests for Relays and Relay Systems Associated with Electric Power Apparatus
Two types of design tests for relays and relay systems that relate to the immunity of this equipment to repetitive electrical transients are specified. Test generator characteristics, test wave-forms, selection of equipment terminals on which tests are to be conducted, test procedures, criteria for acceptance, and documentation of test results are described. This standard has been harmonized with IEC standards where consensus could be reached.
62843-2013 - Standard for N times 64 kilobit per second optical fiber interfaces between teleprotection and multiplexer equipment
An optical interface for use between teleprotection and digital multiplexer equipment that can operate at a data rate of N times 64 kilobit per second where N = 1, 2?12 is described. Requirements for both physical connection and the communications timing are also included.
This standard applies to a line trap inserted into a power circuit to minimize carrier-frequency signal losses. The standard covers line traps in which the main coil is designed as a single phase, air-cooled inductor of the dry type.
