Ultrasonic testing uses ultrasound technology to detect high frequency sounds related to electrical discharges resulting from the ionization of arcing, tracking and corona. Gettle’s ultrasonic testing specialists provide full-service testing solutions that can identify electrical system issues before they lead to disruptions, downtime and in server cases, failure or safety issues.
How Does It Work?
The ultrasonic probe is used to identify any unusual electrical noise such as arcing, tracking and corona within the equipment, which produce ionization and disturb the surrounding air molecules. An ultrasonic probe detects high frequency sounds produced by these emissions and translates them down into the audible ranges. The specific sound quality of each type of emission is heard in headphones while the intensity of the signal is observed on a display panel. These sounds may be recorded and analyzed through highly-specialized ultrasound software for a more accurate diagnosis. Normally, electrical equipment should be silent, although some equipment such as transformers may produce a constant hum, or some steady mechanical noises. These should not be confused with the erratic, sizzling frying, uneven and popping sound of an electrical discharge.
As part of a comprehensive electrical preventative maintenance program or as a stand-alone service, ultrasound inspections may be performed on both open access and enclosed electrical equipment at all voltages (low, medium, and high). Ultrasound technology can be implemented by itself or in conjunction with existing systems such as infrared and vibration analysis for better condition based monitoring results.
Ultrasonic scans deliver a powerful tool to detect system issues and monitor component condition. Contact the Gettle team to learn more about how this technology can deliver critical insight for your business.
