Safely Inspect Your Electrical Assets in an Energized State
Ultrasound inspection using sound ports and handheld testing devices plays a critical role when used in asset inspection and management programs. Anomalies in equipment or components of equipment may create ultrasound waves that, when detected, could alert the maintenance team that a component needs to be further assessed for deterioration. The goal is to find the anomaly, determine the health of the equipment, and fix it if needed before that equipment fails. Condition Based Maintenance programs allow teams to proactively detect and fix defects before costly repairs or full replacements are needed.

Frequently asked questions about IRISS Ultrasound
What is ultrasound inspection in electrical systems?
Ultrasound inspection involves the use of an ultrasound detector to listen for sound that could identify faults in electrical equipment. The sounds emitted by electrical equipment are not normally audible to the human ear, but with specialized equipment from IRISS the ultrasonic audio can be detected, trended, and acted upon.
How does ultrasound inspection work?
Ultrasound inspection works by using a sensor to capture high-frequency sound waves produced by electrical or mechanical faults. The instrument converts those signals into sounds or data the inspector can interpret. This makes it possible to identify issues that are hidden, early-stage, or not yet producing heat.
Why is ultrasound important for electrical maintenance?
Ultrasound is an important addition to the list of reliability inspection technologies because it is complementary to visual and IR inspection. Where there may be no visible damage yet or if it’s too early for the fault to develop a heat signature, ultrasound can detect sound produced by faults at the earliest stage of development.
What are the benefits of ultrasound inspection for asset reliability?
It improves asset reliability by helping teams find faults earlier. It helps the plan maintenance more effectively and avoid unexpected failures. It supports faster diagnosis of electrical and mechanical issues, reducing reactive work and adding another layer of condition data that strengthens long-term reliability.
What is airborne ultrasound and how is it used?
Airborne ultrasound is a form of ultrasound that detects high-frequency sound traveling through the air. In electrical systems and compressed air lines, it means faults can be detected at the earliest stage.
How does ultrasound inspection detect electrical faults?
Ultrasound inspection detects electrical faults by picking up the high-frequency sound energy created when electricity behaves abnormally. Faults like arcing, tracking, and corona generate distinctive ultrasonic signatures that inspection tools can capture, even when the problem is hidden inside enclosed equipment or not yet producing visible damage.
Can ultrasound detect arcing, tracking, and corona discharge?
Yes, ultrasound inspection can detect arcing, tracking, and corona discharge by identifying the ultrasonic sound patterns each fault produces. These electrical issues often begin before heat builds up, which makes ultrasound especially useful for early detection and for locating problems that may not yet appear in thermography results.
How early can ultrasound detect electrical failures?
Ultrasound inspection can detect electrical failure conditions very early, often before a fault creates enough heat to be seen with other methods. Because ultrasound responds to sound generated by electrical discharge, it helps maintenance teams identify developing problems sooner and take corrective action before major damage occurs.
How does ultrasound compare to infrared thermography?
Ultrasound inspection detects sound from faults such as arcing, tracking, and corona, while thermography detects heat. Ultrasound often finds problems earlier, before a thermal pattern appears. Thermography is valuable for confirming temperature-related issues, so the two technologies work best together.
How does ultrasound support condition-based maintenance (CBM)?
Ultrasound inspection supports condition-based maintenance by giving teams real condition data on developing faults instead of relying only on fixed maintenance intervals. By identifying abnormal sound signatures tied to equipment condition, ultrasound helps maintenance teams decide when action is actually needed and avoid unnecessary or delayed intervention.
How does ultrasound help reduce downtime and equipment failure?
Ultrasound inspection helps reduce downtime and equipment failure by catching faults early, before they escalate into breakdowns or forced outages. That gives maintenance teams time to investigate, schedule repairs, and address the root issue in a controlled way, instead of reacting after the equipment has already failed.
What role does ultrasound play in predictive maintenance programs?
Ultrasound works to support PdM by providing substantial data for maintenance teams to record, track, and trend to uncover faults that have yet to produce heat.
What are ultrasound ports and how do they work?
Ultrasound ports are access points on electrical equipment that allow inspectors to safely capture ultrasonic signals without opening the enclosure.
Can ultrasound inspections be performed on energized equipment?
Yes, ultrasound inspection can be performed on energized equipment when proper tools, procedures, and safety protocols are followed. In fact, it is especially valuable in these situations because most electrical faults only appear under operating conditions. Inspection windows and ports help make that process safer and more practical.
What types of electrical equipment can be inspected using ultrasound?
Ultrasound inspection can be used on many types of electrical equipment, including switchgear, motor control centers, transformers, substations, panelboards, disconnects, and distribution systems. Any equipment where arcing, tracking, or corona may develop can benefit from ultrasound, especially when early fault detection is a priority.
How is airborne ultrasound used in electrical inspections?
Airborne ultrasound is used in electrical inspections to detect high-frequency sound emitted by discharge faults such as arcing, tracking, and corona. The inspector scans the equipment with a handheld instrument and listens for abnormal signals or reviews the data. This helps identify hidden electrical problems quickly and safely.
How does ultrasound detect compressed air and gas leaks?
Ultrasound inspection detects compressed air and gas leaks by capturing the high-frequency turbulent sound created as pressurized gas escapes through a small opening. Even leaks that are too small to hear can produce a clear ultrasonic signal.
