Current Transformer on Incorrect Phase

  1. Locate the CT on the Meter page in the Device Setup interface in Tesla One.
  2. Determine which phase the CT should be measuring.
    • Backup Gateway 2 with Tesla 100 A CTs:
      CT1Line 1
      CT2Line 2
      CT3Defaults to Line 1 but can be configured as Line 2 during device setup in Tesla One
  3. Verify the CT is measuring the correct phase.
