T&D How recently posted a video sponsored by Burns & McDonnell called Stray Voltage Sniffing. It features Eversource Energy patrolling the streets at night to detect stray voltage from streetlight poles.

To watch, click here or on the image.

 

Mike Holt's comment: I hate it that they call this Stray Voltage. It's Contact or Fault Voltage, not Stray Voltage.

  • Please, if anyone knows of a commercial or scientific device That can pick up electrical potential difference between two points from that distance I sure would like to know about it.The implication is that this device can determine if there is an alternating electrical potential difference between the pole and the earth whose cause could only be a failure in the prescribed fault carrying conductor. The on board screens show a typical signature one would get from the wide frequency band of an arcing circuit.
