a start is restored without an operate event, the start duration shows the protection
function that has started first.
Start duration that has the value of 100% indicates that a protection function has
operated during the fault. If the protection functions has not operated, though another
function might have operated during this period, Start duration always shows values
less than 100%.
The Fault recorded data Protection and Start duration is from the same protection
function. The Fault recorded data operate time shows the time of the actual fault
period. This value is the time difference between the activation of the internal start and
operate signals. The actual operate time also includes the starting time and the delay
of the output relay. The Fault recorded data Breaker clear time is the time difference
between internal operate signal and activation of CB_CLRD input.
If some functions in relay application are sensitive to start frequently
it might be advisable to set the setting parameter Trig mode to "From
operate". Then only faults that cause an operate event trigger a new
fault recording.
The fault-related current, voltage, frequency, angle values, shot pointer and the active
setting group number are taken from the moment of the operate event, or from the
beginning of the fault if only a start event occurs during the fault. The maximum
current value collects the maximum fault currents during the fault. In case frequency
cannot be measured, nominal frequency is used for frequency and zero for Frequency
gradient and validity is set accordingly.
Measuring mode for phase current and residual current values can be selected with the
Measurement mode setting parameter.
