Problem Description Probable Cause Suggested Solution

When running the excitation test, the Vx voltage is always zero. The excitation current can be raised during a test.

  • The EZCT-2000A X cables are driving a short circuit.
  • Check CT shorting screws

  • Check X lead connections.

When running the excitation test, the Vx voltage can be raised but the excitation current is always zero during a test.

  • The EZCT-2000A X cable is driving an opened circuit.
  • Check the CT terminal connection.
