知装置。 In a device that detects the internal pressure of an electrical device sealed with an insulating fluid and compares the detected data with a predetermined reference value to detect an abnormality in the electrical device, the detected value of the internal pressure is integrated over a certain period of time. An abnormality detection device for electrical equipment, characterized in that data obtained from the integrated value is compared with a predetermined reference value.
