Digsi 4

One Software for all SIPROTEC Protection Relays



DIGSI 4 stands for easy-to-use and user-friendly parameterization and setting of all SIPROTEC protection relays, whatever the version. The PC program runs under MS Windows 95, MS Windows 98, MS Windows NT, MS Windows 2000, MS Windows ME and Windows XP PRO (excepted MS Windows XP home edition). Like its predecessors, DIGSI 4 supports the communication at the rear device interface by means of the IEC 60870-5-103 protocol. In addition to this, this new version allows to connect various field busses such as PROFIBUS, MODBUS, DNS, provided that the devices are equipped with the corresponding communication modules. Because of its modular structure, DIGSI can be used cost-optimized for the requirements in hand. For example, for many standard tasks, the basic program is sufficient, but it can be expanded with optional components to meet requirements immediately or later on. Basic version DIGSI 4 Basis already covers most standard tasks. These include:

  • Setting parameters and routing
  • Human machine interface
  • Commissioning, controlling and checking
  • Communication via a direct connection, via PROFIBUS FMS or other bus system

The complete version DIGSI 4 Professional has a greater functional scope than the basic version with the following additional modules:

  • Display Editor - for creating and modifying default displays and control displays
  • SIGRA - for visualizing and evaluating fault records
  • DIGSI Remote - for remote controlling of SIPROTEC 4 relays via a modem connection
  • CFC - for creating new functionality or for changing the predefined interlock conditions

By the way: If you are already working with the engineering tool SICAM plusTOOLS, you can integrate the functionality of DIGSI 4 seamlessly into the SIMATIC Manager. You can use DIGSI 4 in conjunction with SICAM on the station control level without any problem, too.

Sigra 4

Powerful Analysis of all Protection Fault Records


By means of SIGRA 4, it is possible to analyze fault records, such as those that are recorded by fault recorders when there are disturbances in substations and electrical power stations, in a simple, rapid and convenient manner. The product was designed by practical persons who have experience in the evaluation of faults. Accordingly, in addition to the usual time-signal display of the measured variables recorded, 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, SIGRA 4 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 record simply and conveniently. Additional fault records, e.g. from the opposite end of a line, can be added to the existing fault record. The fault records can be synchronized to a common time basis by means of a synchronizing function, thus improving considerably the quality in fault analysis. SIGRA 4 can be used for all fault records that are available in the COMTRADE file format. The software product is easily and conveniently installed from a CD-ROM, it offers a comprehensive guiding system with demonstration, and an easily readable, practice-orientated manual describes the typical steps involved when using SIGRA. However, the functional features and advantages of SIGRA 4 can, only be shown optimally on the product itself. For this reason, it is possible to test SIGRA 4 for 30 days with the trial version.
