  • Most electrical cabinets are not hermetically sealed. Scan your ultrasound detector around the panel sides and vent holes to detect discharges like arcing, tracking, and corona.
  • Not all electrical discharge faults produce heat. Use ultrasound to hear what your infrared camera cannot see.
  • Electrical discharge activity is amplified by high humidity. When performing ultrasonic scans at substations make note of the date and weather conditions.
  • Ultrasound travels directionally through air compared with audible sound. When scanning from a distance therefore, it is important to inspect electrical systems from all sides.
  • Corona discharge produces no heat on electrical systems below 240 kV so don’t rely entirely on infrared to find problems.
