- Highest stability is case of external faults, also in case of transformer saturation through stabilization with flowing currents
- Operate curve with freely adjustable characteristic-curve sections
- Additional operate curve with increased sensitivity for low current faults, for example in resistance-grounded networks

- 3 interdependent methods of measurement make possible the shortest tripping times in case of busbar faults and ensure maximum stability in case of large flowing short circuit currents
- The integrated circuit-breaker failure protection recognizes circuit-breaker faults in case of busbar short-circuits and generates a tripping signal for the circuit breaker at the remote line end. In case of a failure of a coupler circuit breaker, the adjacent busbar is tripped.
- (Available in the bay unit!)
- Comprehensive monitoring of the current circuits, the measured-value processing and trip circuits prevent over-functions and under-functions of the protection and reduce the effort for routine checks

53.Analysis software of all protection fault records SIGRA
It is of crucial importance after a line fault that the fault is quickly and fully analyzed so that the proper measures can be immediately derived from the evaluation of the cause. As a result, the original line condition can be quickly restored and the downtime reduced to an absolute minimum. lt is possible with the analysis software 4 to display records from digital protection units and fault recorders in various views and measure them, as required, depending on the relevant task.
In addition to the usual time-signal display of the measured variables record, it is also designed to display vector diagrams, circle diagrams, bar charts for indicating the harmonics and data tables. From the measured values which have been recorded in the fault records, it calculates further values, such as: absent quantities in the three-wire system, impedances, outputs, symmetrical components, etc. By means of two measuring cursors, it is possible to evaluate the fault trace simply and conveniently. With SIGRA, however, you can add additional
fault records. The signals of another fault record (e.g. from the opposite end of the line) are added to the current signal pattern by means of Drag & Drop.
The analysis software offers the possibility to display signals from various fault records in one diagram and
fully automatically synchronize these signals to a common time base. In addition to finding out the details of the line fault, the localization of the fault is of special interest.
A precise determination of the fault location will save time that can be used for the on-site inspection of the fault. This aspect is also supported with its “offline fault localization” feature.It can be used for all fault records using the COMTRADE file format.
- Features
- 6 types of diagrams: time signal representation (usual), circle diagram (e.g. for R/X), vector diagram (reading of angles), bar charts (e.g. for visualization of harmonics), table (lists values of several signals at the same instant) and fault locator (shows the location of a fault)

- Powerful zoom function
- User-friendly configuration via drag & drop
- Innovative signal configuration in a clearly-structured matrix
