Abstract

The present invention relates to a handheld device (10) for detecting a partial discharge event, the device comprising: • a first probe (12) having a first partial discharge sensor (14) disposed within; and • a second probe (20) having a second partial discharge sensor (26) disposed within, the second probe being electrically connected to the first probe by a connecting cable (24); • wherein the first and second probes comprise means for measuring a difference in time of arrival of a detected partial discharge event.
