Information on the concepts of protection of ac transmission lines is presented in this guide. Applications of the concepts to accepted transmission line-protection schemes are also presented. Many important issues,…
This part of IEC 62271 applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages…
Small power transformers have become a significant element in distribution systems supplying large commercial customers like major resort hotels and site-specific industrial customers that desire the local utility to own,…
A basis for the electronic reporting of transformer test data on liquid immersed distribution transformers, as defined in the IEEE C57.12.2X, C57.12.3X, and C57.12.4X standards series, is provided in this…
This standard applies to devices used for the purpose of controlling the ground current or the potentials to ground of an alternating current system. These devices are: grounding transformers, ground-fault…
Methodologies for determination of the steady-state winding hottest-spot temperature in dry-type distribution and power transformers with ventilated, sealed, solid cast, and encapsulated windings built in accordance with IEEE Std C57.12.01(TM)…
The test procedures covered by this standard apply to the thermal endurance of solid insulating materials, including processed compositions of raw materials, before they are fabricated into insulating structures identified…
Errors detected in the definition of the characteristic impedance of a transmission line and in the definition of image impedance of a two-part network are corrected.
The purpose of this guide and subsequent revisions to IEEE Std 143-1954 [8]1 is to present some basic considerations for the selection of neutral grounding parameters that will provide for…
