The ST500PGN puts a high magnitude pulse between the neutral/hot leg or hot leg/hot leg for any secondary service (120V, 208, 277, 480V). It cannot be fooled by telephone and cable television bonding often missed by continuous loading devices.
  • Identify bad conductor(s) from the transformer to the meter base
  • Indicate integrity of neutral conductor to prevent excessive house ground currents
  • Locate both hot legs and neutral at the pedestal and/or transformer blocks.
  • Locate bad connectors on overhead spans
  • Identify de-energized URD Primary cable in a manhole or ditch
