ADAPTIVE SAFETY DIAGNOSIS POWER METER

摘要

According to an embodiment of the present invention, an active power meter for measuring power transferred through an external power line comprises an input contact part which is an input terminal of the power line, an output contact part which is an output terminal of the power line, a measurement part which is mounted on the power line to detect a power factor of the power by sensing a value of the transferred current or analyzing a power signal, temperature sensing parts which are respectively mounted in the input contact part and the output contact part to sense the temperature, a control part for determining whether or not there is a leakage current from the current value measured by the measurement part and determining whether or not there is an overheat from the temperature values measured by the temperature sensing parts, and a display part for displaying whether or not there are the leakage current and the overheat of the power meter according to the control of the control part, wherein the control part transmits information corresponding to the sensed values to a user when determining an abnormal operation from the values sensed by the measurement part and the temperature sensing parts.
