ETAP - Protection Time-Current Curves - Current offset error
ETAP - Protection Time-Current Curves - Current offset error
(OP)
When I assign a fuse or relay from the ETAP library to the one-line diagram symbol of an existing ETAP model, ETAP plots the time-current curve offset to the right by a current factor of 1.17.
When I assign the same fuse or relay from the ETAP library to the one-line diagram in a new ETAP model, ETAP correctly plots the time-current curve without the current offset.
Have any ETAP users encountered this problem, and how is it resolved ?

RE: ETAP - Protection Time-Current Curves - Current offset error
I don't know much about ETAP, but the 1.17 is suspiciously close to the actual factor of 1.15 to make me think it is probably related to this.
RE: ETAP - Protection Time-Current Curves - Current offset error
However the "shift factor" is set to 1.00
I have found that by deleting the fuse or relay and re-assigning the identical fuse or relay, the software plots correctly without the shift. This not a satisfactory solution.
