Ultra-high frequency partial discharge array sensor apparatus for high-voltage power apparatus

摘要

Provided is an ultra-high frequency partial discharge array sensor apparatus for detecting an electromagnetic wave partial discharge signal generated due to an internal defect of a high-voltage power apparatus such as a gas insulated switchgear, a power transformer, a reactor, or a high voltage rotating machine. A plurality of array sensors (120a-d) are disposed at regular intervals integrated as one body, thus measuring the position of an internal defect while detecting a discharge signal.
