You download the Manual for SIPROTEC Relays from here : SIPROTEC 4 Downloads You will find all the explanations in the Manual for 7SJ62. Hope this helps Cheers Navnag

Diagnosis is: what happened was overcurrent for a period in phases L1 (115 ms) and L3 (84 ms), and in the case; as the time to trip signal has not reached the relay did not trigger tripping signal to the circuit breaker, this is thought correct?? I appreciate if you can post comments.

That the message doesn't mean a trip, but a pickup? if yes, then it is correct what happened was overcurrent for a period in phases L1 (115 ms) and L3 (84 ms), you didn't write about L3, about L1 it is correct as the time to trip signal has not reached the relay did not trigger tripping signal to the circuit breaker, better described would be: as the pickup time didn't reach the timer for the overcurrent, the protection was not activated and therefore no trip Signal was sent. if you have configured Definite Time, check in Siprotec what is the timer for the Ip. If you have one of the curves (inverse, extreme-inverse etc) than the time depends on the current intensity and this should also be in the trip log I appreciate if you can post comments.
