Acoustic Imaging
Enhance operations and safety with cutting-edge Acoustic Imaging technology. Our services provide companies with precise, real-time insights into system performance, helping to detect leaks, identify structural weaknesses, and optimize maintenance schedules before costly failures occur. With unparalleled accuracy and non-invasive techniques, we ensure uninterrupted service while reducing downtime and operational risks.
Acoustic imaging is an advanced technology that uses ultrasound to create visual representations of disturbances, allowing us to detect and locate issues like gas leaks or mechanical faults. It works by converting sound waves into images, helping us to quickly and accurately identify problems that are otherwise undetectable.
Corona is a luminous, audible discharge that occurs when there is an excessive localized electric field gradient upon an object that causes the ionization and possible electrical breakdown of the air adjacent to this point. Corona is characterized by a colored glow frequently visible in a darkened environment.
One of the significant yet largely invisible threats to power systems is corona partial discharge (Corona PD). Corona PD is both an indicator of malfunction and an active destructive factor that should be eliminated. Over time, the discharges cause damage to the electrical components, eventually leading to system failures.
Detecting corona PD early is crucial to ensure the health of the power system. Accurate and timely detection allows for proactive identification and rectification of potential equipment failures, thus preventing costly, disruptive power outages.
The Precision of Pinpointing: In detecting corona discharges, precisely locating the origin of PD is essential. Accurate localization aids in assessing a fault’s severity and distinguishing between multiple coexisting faults. This differentiation is vital for targeted maintenance efforts.
What is Acoustic Imaging, and
how does it
work?
Acoustic Imaging uses advanced sound wave technology to detect and map anomalies in equipment, like leaks, structural weaknesses, or inefficient operations. It provides a detailed acoustic “map” for real time insights.
How is this different from traditional inspections?
Traditional methods often require equipment shutdowns or manual checks. Acoustic Imaging is non-invasive, works in real time,
and delivers highly accurate results without disrupting operations.
Why is this important for companies?
Companies rely on uninterrupted operations. Acoustic Imaging helps preemptively identify issues, preventing costly failures and ensuring a consistent energy supply.
What kind of ROI
can companies expect?
Companies typically see a reduction in downtime and maintenance costs by 20-30%, along with extended equipment lifespan and better compliance with safety standards.

|
Ultraviolet Technology

Ultrasonic Technology
|
|---|---|---|
|
How it Works
|
Detects corona PD by capturing the ultraviolet photons emitted during the ionization process. The UV camera visualizes these emissions, overlaying them on a visible light image to pinpoint the exact location of the discharge source.
|
Identifies corona PD by capturing the acoustic waves they produce. Using an array of ultrasonic microphones, the technology estimates the source location of the PD by interpolating the sound waves' origins.
|
|
Sensitivity
|
Laboratory-tested and certified sensitivity to PD.
|
Sensitive to acoustic waves caused by PD.
|
|
Imaging
|
Displays an overlay of the UV image atop a visible image, pinpointing corona on components.
|
Offers wide fields of view but lacks detailed pinpointing of the PD source.
|
|
Reliability
|
Minimal false results, reliable and repeatable outcomes.
|
Prone to false positives due to environmental noises and noise reflections.
|
|
Multiple Sources Detection
|
Can easily detect and distinguish multiple sources, without limitation on the number of sources in the field of view.
|
Faces challenges in detecting and distinguishing several sources. Two nearby PD sources often get combined, making precise localization difficult. When in multi- source mode, the probability for false results is high.
|
|
Ease of Use
|
Intuitive "point and shoot" operation, with zooming capabilities on both channels.
|
Requires adjustments and frequent re-positioning during inspection.
|
|
Applications
|
Versatile in use, from handheld devices, vehicle mounted to airborne applications.
|
Handheld use primarily, with requirements to stand still during inspection.
