Device for sensing partial discharge of transformer

Abstract

Provided is a device for sensing a partial discharge of a transformer, the device detecting a partial discharge in a transformer and being capable of measuring the position thereof. The device for sensing a partial discharge of a transformer comprises: a case which is provided in the transformer and which has a hollow portion; an omni-directional first sensor which is disposed at one side in the case and which detects a partial discharge signal of the transformer; and a directional second sensor which is disposed at the other side in the case and which detects the partial discharge signal of the transformer.

Dependencies are inferred from the claim text.
