  1. Aseptic Substation High Voltage In feed Lines 12-15-06 Humidity 38% Temp 68 Degrees Wind 0-2 MPH Sea Level 385’ Clear conditions Tools Used CTRL UL 101 Receiver Power Beam 300 Parabolic reflector A & B Phases are noisy. C phase is silent. Please click on the speaker icons to hear the ultrasonic emissions. Pressing escape once will turn off recording All main transformer high voltage in-feed insulator tops are as noisy as the A Phase in feed line seen here. Zero or near zero ultrasonic emissions were heard from low voltage components feeding the plant. B Phase A Phase

  2. Only the bottom line produces any sound. Norton substation appears to be quiet as well. The ultrasonic emission appears to be coming from the splice as seen in the photo.
