                TFS 2100E - TRAVELLING WAVE FAULT LOCATOR SYSTEM     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. 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.

This testing and maintaining battery system allows to perform measurement of battery voltage, discharging current test and testing of battery capacity. BTS 200 can be connected with external load unit ELU 200. High power battery capacity test system Discharging current up to 1300A with external loads (up to 9) Graphical display showing test parameters, curves and results Internal memory Light and easy to carry, with handles and wheels Shunt or clamp metering of an additional current Suitable for all battery types.

• CODESFRA 5000

SFRA 5000 is a standalone sweep frequency response analyzer for the high accuracy transformer analysis and integrates the STS and TD 5000 family test sets. The SFRA 5000 offers both high precision and portability in a single package, providing all the accessories required for fast, easy to use, reliable and repeatable measurements. Without the need for a PC to compare transformer fingerprints, the SFRA 5000 decreases test time enabling the engineer to complete testing in a much shorter period of time than previously possible. SFRA 5000 is provided with its own embedded software, giving the possibility to the engineer to zoom into a portion of the sweep in order to inspect any differences in the plot in more detail during or after a sweep. This enables diagnosis of transformer faults early on in a transformer sweep, without the need for a PC.

• Max DC voltage output300 V

This protective relay test set is designed to give the commissioning engineers a multitasking and highly reliable testing equipment. Test results and settings saved into local memory TD 1000 Plus model with two current outputs and high power at 15 Hz.
