Sequence of events, fault reports and waveform capture records 164
9
Once current is above a relative pickup level for the specified duration, the relay will alarm and
trigger waveform capture. Waveforms are captured per the settings in “Waveforms” tab of
“Metering & Waveforms” screen
(See section 9.2.1) .
If waveform capture option is not enabled or the maximum number of waveforms has been
reached, the High Current Trigger Relay will no longer record waveforms but still log alarm
events.
NOTE: If the High Current Trigger relay operates (in the same half cycle) at more than one
breaker, each generates an event but only one waveform is captured.
Events
This relay logs the following events:
“Alarm Pickup High Current Trigger” - logged when current at the breaker goes above the
pickup level
“Alarm Dropout High Current Trigger” - logged when current at the breaker goes below the
dropout level
“Alarm High Current Trigger” - logged when function operated (i.e. current stayed above
pickup level for the duration of the set time delay)
“HCTR Waveforms Max Count Reached” - logged when maximum set number of waveforms
has been triggered by the function
“HCTR Waveforms Counter Reset” - logged when user resets waveform count
Alarms
“High Current Trigger - Any”
“High Current Trigger - Breaker X” - where X stands for breaker number from 1 thru 30
9.3.1 Configuration
The High Current Trigger relay is associated to a specific breaker. From the User Setting
sub-menu, click on Relay Protection, select the appropriate breaker and click on the HC Trigger
button.
