The invention relates to an access point transient characteristic identification method, device and equipment. The method comprises the following steps: acquiring recording time of each transient event recorded by each power quality monitoring device; fusing the transient events and the transient events with the same transient event type based on the recording time; establishing a space-time frequency matrix corresponding to the fused transient events; analyzing the space-time frequency matrix to obtain monitoring points with strong correlation; acquiring event feature sets and event frequencies of transient events corresponding to the monitoring points with strong correlation; and judging whether the monitoring points with strong correlation can construct the sensitive user access points or not based on the event feature set and the event frequency, thereby realizing screening of the sensitive user access points. 一种接入点暂态特征识别方法、装置和设备，包括获取各个电能质量监测装置记录的各个暂态事件的记录时间；基于记录时间对各个暂态事件及暂态事件类型相同的暂态事件进行融合；建立融合后的暂态事件对应的时空
