Content of a Fault Record
The information given in a fault record can essentially be divided into 3 parts:
Part 1: Common Information (independent of protection function)
Date and Time
Date and Time of the Fault
Fault No.
This counter will be incremented with each fault (»Prot . Pickup«)
Act Set
The active parameter set
Fault duration
Time period from the rising edge of the General Pickup (»Prot . Pickup«)
signal up to the falling edge of the General Pickup Signal. Please note that
General Pickup is an or-connection (disjunction) of all Pickup signals.
General Trip (»Prot . Trip«) is an OR-connection of all Trips.
Time to trip
The time between pickup and trip. Please note: No time to trip will be
shown if the first pickup and the first trip are issued by different protection
modules.
Pickup
Name of the module that picked up first.
Trip
Name of the module that tripped first.
Active AdaptSet
In case that adaptive sets are used, the number of the active set will be
displayed.
Part 2: Information specific to the protection function that detected the fault
e. g. Fault type
The bits of information given in this part depend on the protection
module.
For example, in case of phase-selective protection functions, there is also
data about the single phases.
