IEEE 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.
IEEE/IEC C37.111-2013 - IEEE/IEC International Standard - Measuring relays and protection equipment ? Part 24: Common format for transient data exchange (COMTRADE) for power systems
Also known as IEC 60255-24 Ed.2, this standard defines a format for files containing transient waveform and event data collected from power systems or power system models. The format is intended to provide an easily interpretable form for use in exchanging data. The standard is for files stored on currently used physical media such as portable external hard drives, USB drives, flash drives, CD, DVD. It is not a standard for transferring data files over communication networks.
IEEE/IEC 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.
