The present invention relates to an integrated management device for partial discharge signals and a method thereof. The device includes: a signal generation unit which generates a signal to a sensor in which partial discharge is to be measured; a sensor signal acquisition unit which acquires signal data outputted from the sensor; a local input terminal signal acquisition unit which acquires signal data outputted from the input terminal of a local unit connected to the sensor; a local output terminal signal acquisition unit which acquires signal data outputted from the output terminal of the local unit connected to the sensor; a signal integrating and management unit which collects the signal data, arranges attenuation of analog signals and digital signals from the sensor, the input terminal of the local unit, and the output terminal of the local unit by frequency and signal intensity, calculates error rates due to the attenuation, and maintains the results in a database; and an integrated signal output unit which outputs signal compensation values for compensating the size and the phase of a pre-stored partial discharge signal based on the error rates.
