C37.111-2013 - IEEE/IEC 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.
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.
