This guide discusses both on-line and off-line partial discharge (PD) measurements on complete windings of any type, as well as measurements on individual form-wound coils and bars. Measurements selected from…
This standard sets terms, test methods, test circuits, measurement procedures and preferred result values for silicon thyristor-based surge protective components used for overvoltage or overcurrent or both protection in low-voltage…
Guidance for technical requirements for the design, fabrication, testing, and installation of indoor gas-insulated substations (GIS) 1 kV up to 52 kV is provided in this standard. Parameters to be…
An electric penetration assembly is an assembly of insulated electric conductors, conductor seals, module seals (if any), and aperture seals that provides the passage of the electric conductors through a…
It is required that Class 1E motors, with their interfaces, meet or exceed the specified performance requirements throughout their service life. This is accomplished through a program that includes, but…
This document provides quantity definitions for designing and using instrumentation for the measurement of electric power quantities under sinusoidal, nonsinusoidal, balanced, and unbalanced conditions.
Metal-clad (MC) medium-voltage switchgear that contains drawout electrically operated circuit breakers is covered. MC switchgear is compartmentalized to isolate components such as instrumentation, main bus, and both incoming and outgoing…
This Guide provides guidance for measuring the electric-field 1 strength, ion-current density, conductivity, monopolar space-charge density, and net space-charge density in the vicinity of HVDC power lines, in converter substations,…
Provides guidance for determining the hottest-spot temperature in distribution and power transformers built in accordance with IEEE Std C57.12.00-2000. Describes the important criteria to be evaluated by a thermal model…
