If you are receiving an Admittance value of 0.00 mS during testing with a Tx Auditor, it may be caused by higher resistance in the CT itself.  This is most often caused by "high-accuracy CT's".  While an Admittance value of 0.00mS typically indicates an open circuit, the Tx Auditor has a resolution of two decimal places and may not always appear to have a valid test when measuring high accuracy CT's.

If you are receiving intermittent software errors when using the TX Auditor, please follow the steps below:
  1. Close out of the Tx Auditor Software by pressing the "X" in the top right corner of the software.
  2. Open a Windows File Explorer
  3. Navigate to C:\Program Files\Radian\RPS
  4. Locate the "TransRatio.db" file.
  5. Move (Cut then Paste) the "TransRatio.db" file to a different location (Desktop or external flash drive).
  6. Re-run the Tx Auditor software.
Please contact technicalsupport@radianresearch.com if you have further questions about this process.  Thanks!

If you would like to obtain more precise readings with the rope primary current probes (AEMC Ampflex), try double-wrapping the probe around the CT.  This will cut down on the amount of noise being read by the probe (due to a smaller radius).  Because of this, you will have to modify what the Tx Auditor software is expecting for current readings.  Navigate to System Info -> IP1 mV/Amp.  Change this value from 1.0 to 2.0 if you have the probe double-wrapped around the CT.  The software will then make corrections for the probe and calculate the ratios accordingly.

I found that I got better results hand positioning the flex at 90 deg. with one pass and squeezing the flex down smaller until each side is touching one another, this further reduces noise by having effectively a smaller circle.

Thanks for the feedback Jim. That is another great option to help reduce testing error when using a flex probe for CT ratio/phase error.
Some people are not aware that there are different sizes of the flex probe as well. If you are consistently having to double wrap then maybe using a smaller diameter probe would help, Instead of using a 48" or 36" probe and double wrapping, get a 24" probe and use Jim's suggestion above. Thanks again Jim!
