Description
Fault Current Indicator Assembly – Technical Description
The fault current indicator assembly generates a fault signal when the preset fault current threshold continues for the detection time defined by the user. When a fault occurs, the user is informed via the internal signal LED, LCD display, and an external signal lamp. Fault information can be transmitted to SCADA or other auxiliary systems through dry contact(s) on the device.
Signal and Reset Dynamics
- LED Indicators: The signal LEDs blink every 2 seconds during the first half of the reset period and every 4 seconds during the second half. The phase or earth current symbol on the main screen also blinks at the same interval as the LED to alert the user.
- Automatic Reset: The device automatically resets 3 seconds after the fault is cleared.
- Manual / Remote Reset: The user can reset the device via the interface or through an optically isolated digital input (remote reset).
- Event Log: The last 20 faults are listed on the “Events” page together with current value, faulty phase, date, and time information.
