Abstract
Disclosed are an apparatus and a method for diagnosing a failure of an electromagnetic-inductive power supply apparatus, which diagnoses whether a power-generation CT has failed by comparing the values detected in a sensor CT and the power-generation CT, thereby preventing the generating efficiency from being reduced. The disclosed apparatus for diagnosing the failure of the electromagnetic-inductive power supply apparatus detects detection values of a power-generation CT and a sensor CT, converts detection values into converted value by scaling detection values, and diagnoses whether the current transformer has failed and whether the power-outage has occurred based on converted values.
