This standard applies only to relays and relay systems used to control power switchgear. It does not cover relays of types designed primarily for industrial control, for switching of communication…
Superseded by IEEE Std C37.90-2005. This standard applies to relay systems that protect and control apparatus that generate, and distribute and use electric power. This standard defines service conditions and…
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 waveforms, selection…
Superseded by IEEE C37.90.1-2002. Design tests intended for protective relays and relay systems, including those incorporating digital processors, are specified. The tests are intended to be applied to a complete…
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…
A design test to evaluate the susceptibility of protective relays to single-frequency electromagnetic fields in the radio frequency domain, such as those generated by portable or mobile radio transceivers is…
Reaffirmed March 2012. This standard describes test procedure, test point selection, test level, and acceptance criteria for repeatable electrostatic discharge immunity evaluations for tabletop and floor-standing protective relay equipment. Simulator…
The protection of power transformers is covered;various electrical protection schemes are explored;and guidelines are given for the application of these schemes to transformers. Alternative detection methods including mechanical,thermal,and gas analysis…
