NEW TFS 2100E - THE MOST ACCURATE TRAVELLING WAVE FAULT LOCATOR SYSTEM> may 2014
The new ISA TFS 2100E system is the most accurate and easy to install travelling wave fault locator system. The all-in-one solution for the HV network fault location, the system is made of:
- TDU 100E: the device installed at substations.
- TAS 2100E: the software installed into the Master Unit.
It applies to any type of network: AC or DC and thanks to its automatic calculation of the fault distance, fastness as the fault is located in few milliseconds and accuracy, providing the location of the error in less than 150 m, TFS 2100E minimizes the line outage time.

Last, the steady voltage output power is increased from 30 VA to 50 VA.
The test set is also available as 15 Hz model: it has two current outputs to test differential relay and, in addition to that, high power is available at 15 Hz. This allows testing old railway and generator protection relays. This model does not have the DC battery simulator.
TD 1000 Plus is available in 4 different models:
- D 1000 Plus – 220 V
- TD 1000 Plus – 115 V
- TD 1000 Plus 15 Hz – 220 V
- TD 1000 Plus 15 Hz – 115 V
