Guidance for the use and application of Rogowski coils (RCs) (air-core current sensors) for protective relaying in electric power systems is described and provided in this guide. The selection and…
Guidance for the application of ac high-voltage circuit breakers for shunt reactor switching is provided. Overvoltage generation for the three cases of shunt reactors being directly grounded, ungrounded, or grounded…
Specifications for high-voltage (above 1000 V) distribution class enclosed single-pole air switches and associated accessories with rated voltages from 1 kV through 8.3 kV are established. All of these devices…
Design and production tests and requirements for the integrity of submersible electrical equipment intended for installation in submerged or partially submerged environments are covered in this standard. These enclosures contain…
A uniform method is established for determining the temperature classification for the insulation systems for dry-type power and distribution transformers by testing rather than by chemical composition. These insulation systems…
Terminology and indices for reporting and analyzing outage occurrences of transmission facilities are defined in this standard. Outage definitions and indices are given for two general types of facilities: units…
General recommendations for measuring voltage transients in dry-type distribution and power transformers are provided. Recurrent surge voltage generator circuitry, instrumentation, test sample, test point location, mounting the test coil, conducting…
