Temporary DI Fault
Faults due to current variations can also be indicated by the rate of change of the phase current (di/dt) and it is
termed as DI fault.
SICAM FSI detects the rate of change of current (di/dt) typically in 2 cycles ± 1 cycle, depending on current
magnitude.
The device indicates the temporary DI fault via LEDs with a flashing pattern of 2 flash of 50 ms every 2 s or 6 s
depending on the device variant selected.
