Anotation

New IEEE Standard - Active - Draft.
Power transformers are vital equipment in power systems. Winding deformation being the main cause for the decrease of short-circuit withstand and mechanical stability for transformers is shown by statistics and research. The vibration test involves the measurement and analysis of the vibration signals on the transformer tank surface, which is a method to detect, monitor, and evaluate the winding deformation of energized transformers. The execution and evaluation methodology of vibration tests, applicable for oil-immersed power transformers rated above 66 kV, are described by this guide.
