Apparatus and method for monitoring performance of power line filter

Abstract

An apparatus and method for monitoring the performance of a power line filter. The apparatus for monitoring the performance of a power line filter includes a performance degradation monitoring unit for monitoring performance degradation of individual components constituting a power line filter, and then generating performance degradation information, a frequency characteristic measurement unit for measuring frequency characteristics of the power line filter, and a performance monitoring unit for determining at least one of an operating state and performance of the power line filter based on the performance degradation information of the individual components and information on the frequency characteristics of the power line filter.
