T-IED 23kV
T-IED 23kV has total functions for metering, monitoring, control,
protection, and interlock, which are needed for substation automation
based on IEC61850.
It’s available to be various and flexible engineering with high speed PLC
functions for the protective functions .
For DI/DO point, it’s possible to check more conditions and control output
By choosing the expanded structure.
T-IED23kV is the next generation power monitoring and protection device
to manage the power system much more conveniently
by embedding IEC61850 communication, PLC logic and other functions.
Main Functions
- Substation automation IED
- Saved accident waveform
- Changeable logic(PLC)
- Supported IEC61850 protocol
- Various measurement
- Control the circuit breaker
- Embedded digital filter(DFT)
- Various monitoring functions
- Real time analysis for Vector
- Analysis for Event |
