This specification applies to those parts of Network Rail's 25 kV a.c., 50 Hz electrified railway infrastructure, which includes the use of traction return conductors and booster transformers. It mandates the requirements for the operation of Network Rail's 25 kV a.c., 50 Hz electrified...
Electric Power Transformer Engineering, Third Edition expounds the latest information and developments to engineers who are familiar with basic principles and applications, perhaps including a hands-on working knowledge of power transformers. Targeting all from the merely curious to...
Foreword (This Foreword is not part of Amencan National Standard C57.12.55-1987.) The High Voltage Apparatus Coordinating Committee (HVACC) was established July 24, 1972 by the Electrical and Electronic Technical Advisory Board (now superseded by the Electrical and Electronic Standards Management...
The recommendations presented in this guide apply to the inspection, installation, and maintenance of liquidimmersed power transformers rated 501 kVA and above with secondary voltages of 1000 V and above. This guide covers the entire range of power transformers, including extra...
Introduction The recommendations presented in this guide apply primarily to modern large oilimmersed power transformers with high-voltage windings rated 345 kV and above. This guide is a supplement to ANSI/IEEE C57.12.11- 1980, Guide for Installation of Oil-Immersed...
This standard covers conformance tests and requirements for liquid-filled transformers. Such transformers may be remotely or integrally associated with either primary and secondary switchgear or substations, or both, and rated not greater than 2500 kVA, with voltages not exceeding 38...
Scope and Introduction The recommendations presented in this guide primarily apply to new large oil-immersed power transformers with high-voltage windings rated 69-287 kV inclusive. However, appropriate sections of the guide may be applied to lower voltage transformers when similar...
This recommended practice covers general recommendations for the application, installation, operation, and maintenance of all single and polyphase ventilated, non-ventilated, and sealed dry-type distribution and power transformers or autotransformers, including those with solid-cast...
