ARCHI 9000 is a high-end digital fault recorder system designed for recording disturbances and events occurring in substations.
The device performs digital recording of analog signals and binary inputs with a sampling rate ranging from 0.5 to 20 kHz* for fast-changing recordings, and 0.1 to 120 seconds for slow-changing (vector) recordings.
It is a fully scalable system, supporting up to 128 analog channels, up to 32 channels for frequency recording and up to 720 binary inputs within a single substation.
With the free SAZ2000 software, users can analyze recorded data and build centralized fault recording systems covering large-scale power grids.
*) As of early 2025, new versions of ARCHI LGU have entered production; featuring new, 10 times faster processor, twice as much RAM 8MB and increased sampling rate.
The Digital Fault Recorder System allows for recording fast-changing disturbances by digitizing analog signals, currents and voltages, and binary signals supplied from selected station circuits. Records all data occurring before, during and after the disturbance. An unlimited number of ARCHI 9000 systems can be installed on one energy facility. The system operates with synchronized clocks and with synchronized sampling of the 1PPS and GPS signals.
The SAZ2000 program allows for simultaneous analysis of many registration systems located in any geographical area.
The disturbance recording system includes the following basic parts:
