Standard Details

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.

Existing Standards	Superseded C37.90.1-2002 - IEEE Standard Surge Withstand Capability (SWC) Tests for Relays and Relay Systems Associated with Electric Power Apparatus Two types of design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.
	Superseded -2012 - IEEE Power Systems Relays Standards Collection: VuSpec Power System Relays Standards concentrate on the application, design, construction and operation of protective, regulating, monitoring, reclosing, synch-check, synchronizing and auxiliary relays. This includes items used in the operation of relays and relaying systems in the transmission, generation, distribution and utilization of electrical energy and their effect on system operation. This indispensable collection of standards is ideal for electrical and electronics, power, high-voltage, insulation, electrical-power, transmission and distribution, and industrial engineers; and power system researchers and technicians.

	Active 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.
	Active C93.3-1995 - American National Standard--Requirements for Power-Line Carrier Line Traps 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.
