PwrTrans-TapChgr - Power Transformers - Tap Changers
|IEEE Program Manager|
Electrical and mechanical performance and test requirements for load tap changers installed in power transformers and voltage regulating transformers of all voltage and kVA ratings are covered.
This standard covers electrical and mechanical performance and test requirements for tap changers installed in voltage regulating power and distribution transformers of all voltage and kVA ratings. It covers load tap changers (LTCs), also known as on-load tap changers (OLTCs), which can change taps while the transformer is energized and carrying load; and it covers de-energized tap changers (DETCs), also known as off-circuit tap changers, which may be operated only while the transformer is not energized. For load tap changers, this standard covers both resistor and reactor types. It also covers certain aspects of the attendant tap changer motor-drive mechanism. It does not cover the tap changer control system (manual or automatic).
60214-2-2019 - IEEE/IEC Approved Draft International Standard for Tap-Changers - Part 2: Application Guide
This part of IEC 60214 is intended to assist in the selection of tap-changers designed in accordance with IEC 60214-1 or IEEE Std. C57.131 for use in conjunction with the tapped windings of transformers or reactors. It is also intended to assist in understanding the various types of tap-changers and their associated equipment available. The application guide covers on-load tap-changers (resistor and reactor types) and de-energized tap-changers.
