Classification of transformer state.

Level	Relative degree of degradation	Meaning
Normal	[0, 0.2]	Normal equipment: the transformer can run stably and healthily
Attention	(0.2, 0.4]	Suspicious equipment state: the transformer can continue to run under the premise of enhanced monitoring
Abnormal	(0.4, 0.7]	The equipment is in a poor condition or has minor defects
Serious	(0.7, 1]	Equipment has a serious failure and needs to arrange overhaul as soon as possible
