Abstract
A partial discharge measurement device includes: an impulse voltage application unit; a measurement control unit; and first and second partial discharge detection unit. The measurement control unit includes: a first and a second detector level partial discharge counting unit; and a partial discharge resistance evaluation unit. Each of the first and the second detector level partial discharge counting units outputs a first or second detection signal when the first or second detection signal exceeds a predetermined specified value. The partial discharge resistance evaluation unit counts the number of occurrences of partial discharge based on an output from the first and second detector level partial discharge counting unit, and regards the impulse voltage value at which the count value has reached a predetermined value as a partial discharge inception voltage under the repeated impulse voltage application.
