Abstract:
The present invention improves the accuracy of determining the cause of an abnormality occurring in a power meter. In an external server (30), a receiving unit (33) receives, from a power meter (10), temperature information at a plurality of positions of the power meter (10), and input voltage information and consumption current information of the power meter. A determination processing unit (31) determines the cause of an abnormality occurring in the power meter according to a combination of an input voltage, a consumption current value, and an abnormality-occurring position where a temperature exceeds a temperature threshold.
