You also should place a set of a set of
Block
for setting [
ZCSR-VTFBlk
] because the operation
of the ZCSR should stop when the VTF is detected. Conversely, you should place a set of
Non
for the setting were you to require the ZCSR operation keeping in the VTF detection.
Make sure that the ZCSF does not supply the offset feature while the ZCSR supplies the offset
feature. The settings for the offset element are fixed at 7.5 Ω for 1 A rating or 1.5 Ω for 5 A
rating. The fix offset makes the ZCSR operate constantly even when the three-phase fault
appears close in the reverse side. However, the ZCSF blocks its operation in the three-phase
fault because the ZCSR runs together with the ZCSF. As a result, the command protection can
avoid improper operations.
