ISA Protective relay testing
TFS 2100E . Travelling wave fault locator system
- TDU 100E: the device installed at substations.
- TAS 2100E: the software installed into the Master Unit. Main features:
- The all-in-one solution for the HV network fault location
- Accuracy: location error less than ± 50m (less than one tower)
- Fast: the fault is located in few milliseconds
- Unaffected by fault resistance
- The GPS synchronization is embedded into TDU 100E
- Suitable for all kind of power lines AC and DC
- Automatic distance to fault calculation
- The Wide area fault location collects data from the whole network
- The location is performed directly on the network map
- Unlimited number of monitored lines
- Reduce overhead lines outage time
- Non intrusive installation and easy to set up
- Master Station software for distance to fault calculation and analysis
- Connection types available: INTERNET, MODEM and POINT TO POINT
- Substation connection also via the IEC61850-8 interface.
