Title:
APPARATUS AND METHOD FOR DIAGNOSING FAILURE OF ELECTROMAGNETIC-INDUCTIVE POWER SUPPLY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/070777
Kind Code:
A1
Abstract:
Disclosed are an apparatus and a method for diagnosing a failure of an electromagnetic-inductive power supply apparatus, whereby a failure or not of a power-generation current transformer is diagnosed by comparing values (i.e., of a current, a voltage, power) detected by a sensor current transformer and the power-generation current transformer, and thus the generating efficiency of an electromagnetic-inductive-type power supply apparatus is prevented from being reduced. The disclosed apparatus for diagnosing a failure of an electromagnetic-inductive power supply apparatus detects electrical properties of a power-generation current transformer and a sensor current transformer, scales at least one of a power-generation CT detection value and a sensor CT detection value, and converts same into a power-generation CT converted value and a sensor CT converted value, and diagnoses a current transformer failure or not and power outage or not on the basis of the converted power-generation CT converted value and sensor CT converted value.
