In a large majority of cases, the typical slip can be set at around 20 to 40 mHz. This is the situation for
short lines.
In lines with short “dead times”, that is, immediate reclosing in the remote end, with very similar
operation in case of internal faults in both circuit breakers and channel transmission times less than 25
ms, the slip setting may be set at 200 to 250 mHz.
In any case, the order and operating times of the different elements involved should be observed;
these are the elements with which the synchronism check relay must be coordinated, and whose
typical magnitudes are shown on the following page.
