Description
The release is able to record the last 30 openings of the circuit-breaker (trips) caused by
protection trips.
The openings are correlated by the following information:
• The protection that tripped.
• The progressive number of the opening.
• The date and time of the opening (referring to the internal clock).
• The measurements associated to the trip protection.
NOTE:
• Each opening is associated to a progressive number that is incremented with every
trip.
• If the release has exceeded the threshold of the 30 openings, the oldest ones are
progressively overwritten.
Correlated measurements
