Область применения

This Guide addresses the application of transformers in the presence of oscillatory switchingtransients. These oscillatory transients are typically produced by the interaction of theswitching device, transformer, load, and system. This Guide defines operating conditions thatmay produce switching voltages damaging to the transformer insulation system. It discussesthe electrical characteristics of the system source, switching device, transformer, and load andthe nature of their transient interaction. It outlines several mitigation methods. Two examplesare included.This Guide recognizes that many devices and/or system operations can produceoscillatory transient waveforms. The focus of this Guide is on the interaction between atransformer, the system, and a switching device as a result of several reports of transformerinternal winding failures.This Guide focuses only on mechanical switching devices and does not cover semiconductorswitching devices. Transformers that are inductively loaded (reactors, or stalled or acceleratingmotors) are not covered by this document but are addressed by several other referenced publications.
