The inverse-time characteristics of overcurrent relays are defined in this standard. Operating equations and allowances are provided in the standard. The standard defines an integral equation for microprocessor relays that…
This newly developed guide compiles information on the application considerations of protective relays to ac transmission lines. The guide describes accepted transmission line protection schemes and the different electrical system…
Electrical faults on transmission and distribution lines are detected and isolated by system protective devices. Once the fault has been cleared, outage times can be reduced if the location of…
The application of protective relays on transmission-line series capacitor banks is covered. The purpose of this guide is to provide the reader with ample discussion of the protection and control…
Information on the application of under frequency load shedding and restoration to ac power systems is compiled in this guide. Various system conditions that may require the use of under…
Superseded by C37.122-1993.. The technical requirements for the design, fabrication, testing, and installation of a gasinsulated substation (GIS) are covered. The parameters to be supplied by the purchaser are set,…
Guidelines for the application of automatic reclosing facilities to circuit breakers are established. Decisions concerning the use of such facilities in specific cases are left to the user.
This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. The basic principles, requirements, and methods for qualifying Class 1E protective relays and auxiliaries,…
