Current Transformers

Packet Power products are calibrated for use with certain CTs. It is important that you use the meter with the CTs that it is calibrated for. Pay particular attention to CT orientation! The direction that the CT faces on the conductor matters. CTs installed backwards will produce negative power readings and may need to be reinstalled.

CT specification sheets, including important information on correct CT orientation, can be found below.

If you would like information on additional CT options, please contact support@packetpower.com..
