The present invention relates to a partial discharge determination device with a noise removing function and a method thereof. The partial discharge determination device disclosed in the present invention includes: a sensor unit which senses an electromagnetic signal from a power device; an RF signal processing unit which filters the sensed electromagnetic signal and converts the filtered electromagnetic signal into a digital signal; a power frequency synchronization signal detection unit which removes the power frequency synchronization signal included in the digital signal and generates a first filtering signal; a mobile phone signal detection unit which removes the mobile phone signal included in the first filtering signal and generates a second filtering signal; other external signal detection unit which removes other external signals included in the second filtering signal and generates a third filtering signal; and a communication unit which transmits the third filtering signal to a server which determines the partial discharge.
