Passive ultrasonic listening detects high-frequency sound waves above the range of human hearing to conduct electrical and mechanical inspections. This non-contact, non-destructive form of inspection locates specific sounds, even in areas with considerable ambient noise. Our experts at ATS analyze the resulting waveform for any irregularities indicative of potential faults. Ultrasonic listening assesses on-line equipment, often before vibration analysis is a viable diagnostic option. This method’s detection speed and ease-of-use on the shop floor make it a versatile option for equipment evaluation.
Passive ultrasonics can supplement infrared thermography (IR) in potentially hazardous situations, especially in medium- or high-voltage enclosures. Our ultrasonic inspections benefit clients in both long-term, result trending applications, as well as short-term troubleshooting. Our knowledgeable technicians operate ultrasonic technology to our clients’ greatest benefit.
Detecting Electrical and Mechanical Faults
Passive ultrasonics can identify several types of mechanical problems. Friction between moving components, such as couplings or gear mesh, creates ultrasonic waves. Ultrasonic listening picks up these wavelengths, allowing technicians to identify flaws such as bearing anomalies, steam traps, and flow issues. This technology can also identify leaks in pressurized or vacuum vessels by detecting the turbulent flow of the gas or liquid from the pressurized to the depressurized environment. Detecting large and small leaks saves clients from costly energy expenses.
Ultrasonic technology also benefits electric condition monitoring practices by detecting events before flashover (arc flash) incidents occur. Ultrasonic listening can also locate most electrical anomalies, such as arcing, tracking, and corona. Passive ultrasonics consistently finds corona and tracking in circumstances where IR usually cannot. This technique even detects electrical anomalies in enclosed cabinets, whereas IR generally will not without access to a port.
