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.
    • Tesla Remote Energy Meter with Tesla 200 A CTs:
      CT1Line 1
      CT2Line 2
      CT3Line 2
      CT4N/A (CT4 functionality will be available at a later date)
  3. Verify the CT is measuring the correct phase.
