Systems and methods for detecting partial discharge in electrical components

摘要

A system for detecting partial discharge in electrical components may include a control system that may operate a drive in an industrial automation system. The industrial automation system may include the electrical components being analyzed for partial discharge. The system may also include one or more acoustic sensors that may detect one or more acoustic waveforms generated within at least one of the electrical components. The system may also include a monitoring system that may receive the acoustic waveforms from the acoustic sensors and determine whether the one electrical component is experiencing partial discharge based on the acoustic waveforms. The monitoring system may then send a notification to the control system when the one electrical component is determined to be experiencing partial discharge, such that the notification indicates that the one electrical component is experiencing partial discharge.

1. A system, comprising:
a control system configured to operate a drive in an industrial automation system, wherein the industrial automation system comprises one or more electrical components electrically coupled to the drive, and wherein the drive comprises a rectifier configured to convert an alternating current (AC) voltage into a direct current (DC) voltage and an inverter configured to convert the DC voltage into a controllable AC voltage; one or more acoustic sensors configured to detect one or more acoustic waveforms generated within at least one of the electrical components; a monitoring system configured to:
receive the acoustic waveforms from the acoustic sensors while the drive produces the controllable AC voltage;determine whether the at least one of the electrical components is experiencing partial discharge based on the acoustic waveforms; andsend a notification to the control system when the at least one of the electrical components is determined to be experiencing partial discharge, wherein the notification indicates that the at least one of the electrical components is experiencing partial discharge.
