Q. What will happen if the polarities are reversed for each of the CT?
A. The Polaris only considers the absolute value of the current and disregards the
direction; thus, the current and energy values can only be positive. However, we
still recommended that the CTs be connected with the correct wiring orientation.
Q.
What does Polaris message “cht-01” mean?
A. It means that the circuit currently being measured has a power factor that is less
than 0.5. This is not normal behavior and could be caused by having the phases
reversed (voltage and current phases are not properly matched), or there may be
some run-down equipment that are in need of repair or replacement. Check to
make sure that the voltage and current inputs are matched properly, if they are,
they check the condition of equipment on the circuit being measured.
Q. I have checked and followed all the troubleshooting guidelines but my
problem is still not resolved; what should I do?
A. Contact our technical support by phone or email before concluding that the unit is
faulty and removing it. Our technical support team will help to diagnose your
problem and provide advice on potential fixes. Please see Section 7,
Supplementary Information , for our contact info.
