Airborne Ultrasonic Testing

for Electrical Systems

Detect Electrical Defects or Damages Quickly and Economically

The goal of every airborne ultrasonic inspection for electrical equipment is to survey designated electrical equipment in order to pinpoint defective/damaged components within your power distribution system. If unfound or untreated these issues can cause potential fire, explosion, or electrical service interruption threats. These conditions are typically caused by unbalanced or overloaded electrical circuits, loose connections, or broken/damaged equipment and are not visible to the naked eye.

Airborne Ultrasonic Electrical Inspection Services


Airborne Ultrasonic testing for electrical system is a non-contact test that uses ultrasound technology to detect high frequency sounds related to electrical discharges resulting from the ionization of arcing, tracking and corona. Together with thermographic infrared inspections, airborne ultrasonic scanning provides significant insurance against an unscheduled outage, equipment damage or a fire.

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.

Performing an Airborne Ultrasonic Inspection will help you:

  1. Maintain the integrity of your facility’s electrical system
  2. Reduces electrical fire hazards
  3. Provide uninterrupted power to tenants/clients/employees
  4. Detect faulty connections/overloaded circuits
  5. Provide a snapshot in time of the condition of your mechanical systems, motors, bearings, etc.
  6. Preventative or predictive maintenance programs save money by reducing:
    • pre-mature equipment failure
    • emergency overtime
    • overnight shipment of parts
    • insurance premiums (many insurance companies give discounts for performing regular infrared inspections)
    • loss of revenue due to downtime

Work Process

Ultrasound inspections may be performed on both open access and enclosed electrical equipment at all voltages (low, medium, and high).

Our certified ultrasonic inspectors quickly and non-destructively pinpoint electrical and mechanical problems that can not be seen with the naked eye, such as loose connections, faulty breakers, disconnects, overloaded circuits, imbalanced loads, weak motor windings and bearings, and much more.

Detection and recording of noise problems are completed by the ultrasonic technician.

During the electrical infrared survey, our team will generally inspect the following equipment but can provide inspection and imaging on any electrical or mechanical components according to your specification.

  • Switch Gear
  • Transformers
  • Service Disconnects
  • Transfer Switches
  • Bus Runs
  • Motors / Pumps / Bearings
  • Lighting / Heating Contactors
  • Motor Control Centers
  • Breaker Panels
  • Starters
  • UPS Equipment
  • Chillers and Roof Top HVAC Equipment
  • VFDs
