This test procedure applies to the detection and measurement by the wide-band apparent charge method of partial discharges occurring in liquid-filled power transformers and shunt reactors during dielectric test where…
The detection and measurement by the wide-band apparent charge method of partial discharges occurring in liquid-filled power transformers and shunt reactors during dielectric tests are covered. This standard covers the…
IEEE C57.114-1990, IEEE Seismic Guide for Power Transformers and Reactors, specifies recommendations for the design and installation of power transformers and reactors to withstand the effects of earthquakes.
The guide covers modern power transformers rated above 100 MVA, three-phase equivalent and 65 °C rise. The general approach is tutorial. Four different types of loading, that is, normal life…
The selection, application, and specification considerations for the unit transformer and unit auxiliaries transformers are described, taking into account their connections, voltage and kilovoltampere ratings, and excitation and through-fault capabilities…
Conformance test requirements are provided for current and inductively-coupled voltage transformers used for measurement and control functions in unit substations at primary system voltages above 600 V, but not exceeding…
Superseded by IEEE Std C57.13.3-2005 General and specific recommendations for grounding current and voltage transformer secondary circuits and cases of connected equipment are provided. The practices recommended apply to all…
This IEEE Standards product is part of the C57 family on Power Distribution and Regulating Transformers. Electrical, mechanical, and safety requirements are set forth for step-voltage and induction-voltage regulators, single-phase…
