<p>The present invention relates to a discharge detection device. A technical problem to be solved is estimating a discharge position and a discharge quantity in real time by the voltage value measured by a first electrical field sensor set arranged on one side of a measurement space for the discharge detection and a second electrical field sensor set arranged on the opposite side of the one side. The detection device comprises: multiple electrical field sensors arranged in the measurement space for the discharge detection; an input signal preprocessor filtering noise after receiving the voltage and a displacement current measured by a plurality of the electrical field sensor; a data process and analysis system estimating the discharge position and the discharge quantity by receiving a plurality of the voltage value and the current value filtered noise by the input signal preprocessor.</p> |
