ARC FLASH CHAPTER 6: METERING
CTS SYM QUOTIENT
Range: 0.00 to 1.00 in steps of 0.01
Default: 0.00
This value is the quotient (I
min
/I
max
) from the symmetry check in the CT Supervision
element.
CTS DIFF CURRENT
Range: 0.000 to 120000.000 A in steps of 0.001
Default: 0.000 A
This value is the differential current magnitude between the calculated 3I0 and the
measured ground current
The CTS Diff. Current reflects the quantity obtained based on the Diff. IG Polarity setting
in the differential check section of the CT Supervision element.
